The Importance of An Eye Exam

Why You Need An Eye Exam

The end of the year is fast approaching – when was the last time you had an eye exam? Was it a comprehensive eye exam?
eye exam
To keep your eyes healthy and maintain your vision, the American Optometric Association (AOA) recommends a comprehensive eye exam every two years for adults ages 18 to 60, and annual exams for people age 61 and older. However, if you have a family history of eye disease (glaucoma, macular degeneration, etc.), diabetes or high blood pressure, or have had an eye injury or surgery, you should have a comprehensive exam every year, unless otherwise indicated by your doctor.
Also, adults who wear contact lenses should have annual eye exams.

An important part of the comprehensive eye exam is the dilated eye exam to look inside your eye. Drops are placed in each eye to widen the pupil and allow more light to enter the eye. This gives your doctor a clear view of important tissues at the back of the eye, including the retina, the macula, and the optic nerve. This allows for early diagnosis of sight-threatening eye diseases like age-related macular degeneration, diabetic retinopathy, glaucoma, etc.

To better understand the importance of the dilated eye exam, here is a video from the National Eye Institute (NE) that explains what to expect.

At the end of your comprehensive eye exam your doctor should raise any concerns he has with you. But it is up to you to be prepared to react and ask questions for peace of mind and to help save your vision.

Questions To Ask After Your Eye Exam

It is always important to know if anything about your eyes have changed since your last visit. If the doctor says no, then the only thing you need to know is when they want to see you again.

If the doctor says the have been some minor changes, you need to know what questions to ask, such as:

  • Is my condition stable, or can I lose more sight?
  • What new symptoms should I watch out for?
  • Is there anything I can do to improve or help my vision?
  • When is the next time you want to see me?

If the doctor sees a marked change in your vision or give you a diagnosis of eye disease, you would want to ask:

  • Are there treatments for my eye disease?
  • When should I start treatment and how long will it last?
  • What are the benefits of this treatment and how successful is it?
  • What are the risks and possible side effects associated with this treatment?
  • Are there any foods, medications, or activities I should avoid while I am undergoing this treatment?
  • If I need to take medication, what should I do if I miss a dose or have a reaction?
  • Are there any other treatments available?
  • Will I need more tests necessary later?
  • How often should I schedule follow-up visits? Should I be monitored on a regular basis?
  • Am I still safe to drive?

Your vision is a terrible thing to lose, but with proper diet, exercise and no smoking, along with regularly scheduled eye exams, you improve your chances of maintaining your sight.

Best’s Disease

In 1905, Friedrich Best presented a detailed pedigree of an inherited retinal condition referred to as vitelliform dystrophy, or Best’s disease. Best’s disease is an inherited dystrophy of the macula that primarily involves cells known as retinal pigment epithelium (RPE).

best's disease
Friedrich Best

Best’s typically affects both eyes and presents itself either in childhood or early adulthood. Visual acuity is usually minimally affected early on in the course. As the condition progresses, the vision can slowly begin to deteriorate. The rate of progression or the overall amount of progression is difficult to predict. The rate of progression may be also be asymmetric, with one eye progressing at a different rate than the other. Some patients may notice the development of scotoma, or “blind spot”, in their central vision as the condition progresses. Other patients may not progress to later stages or experience vision loss. Loss of peripheral, or side vision, is not expected with Best’s.

Best's disease
Best’s disease
The diagnosis of Best’s disease is primarily based on a careful clinical exam. Taking a careful family history is also important as Best’s is typically inherited in an autosomal dominant pattern. This means that an affected individual has a 50 percent chance of passing the gene to their offspring. It should be noted though that there is highly variable expression, which means there may be some affected individuals in whom the changes are so mild that they never notice any visual disturbance. The causative gene is located on chromosome 11 and has been labeled BEST1 (VMD2). This encodes for a protein known as bestrophin 1, which is located on the membrane of RPE cells. It is believed that this protein is involved in RPE metabolism through its control of chloride channels, although the details are still being elucidated. Thus far, there have been over 200 mutations of the BEST1 gene that have been described.

The classic exam finding in Best’s is a circular yellow lesion in the macula. This lesion resembles an “egg-yolk”, and is often referred to as such by ophthalmologists. As the condition progresses, the yellow material begins to break up and the pigmentation of the macula attains a more mottled appearance. This is often referred to as a “scrambled egg” appearance. After many years, there may be evidence of cell loss in the macula, which can negatively impact the visual acuity. In a relatively small proportion of cases, a complication can occur in which abnormal blood vessels grow underneath the macula and begin to leak fluid and/or blood into the macula. This is known as choroidal neovascularization (CNV), and can be vision threatening. Fortunately , CNV can be treated effectively with medications that are injected into the eye as part of a straightforward and low-risk office procedure. Typical signs of CNV would include distortion or blurring of the vision, and it is important to notify your doctor of any sudden changes in vision.

Diagnostic testing is sometimes used to confirm the diagnosis. The electro-oculogram (EOG) is universally abnormal in Best’s, and can be a valuable confirmatory test. Fluorescein angiography and optical coherence tomography can be valuable tests to better evaluate the macula and to also look for the development of CNV. Genetic testing for Best’s is now possible as well.

There is no established medical or surgical management for Best’s disease. In patients who develop CNV as a secondary complication, existing treatment options are effective. Future avenues of therapy hold significant promise, but are in their early stages of development. Stem cell based therapies, for example, have the potential to help restore healthy cells that may have been lost during the disease progression.

Increased Awareness for Saving Vision

The following is a survey done by Essilor (a French company that produces ophthalmic lenses along with ophthalmic optical equipment) and a large marketing research firm in the UK, YouGov. While the focus in on people living in the UK, the results would probably be similar to the US population. Even with increased access to the Internet, many people are still not aware of the risks associated with eye disease and what they can do to help retain their vision. Increased awareness of informational resources are important for saving vision.
saving vision
There are a number of websites with easy to understand information about taking care of your vision that I have listed under Resources to Help Save Vision at the bottom of this article. And while there are eye diseases that are hereditary, you can slow the onset and progression by making good lifestyle choices about smoking, diet and exercise. Your eye care specialist is also an excellent source of information about what you can to do reduce your risk of vision loss, at any age.

Increased Awareness for Saving Vision

A YouGov poll conducted with Essilor reveals that most Britons are unaware of damage to their eyes by surrounding objects, activities, and devices. This widespread lack of awareness means fewer people seeking methods of prevention and avoidance, and for those that are aware of risks, most are not informed of existing preventative measures.

The poll has shown* that many British people remain uninformed about the various ways in which eyes are damaged by common daily factors, despite evidence that eye health is affected by blue light, UV rays (reflected from common surfaces), diet, obesity, and smoking.
Of the 2,096 people polled, the percentage of respondents aware of the link between known factors affecting and eye health were:

  • Poor diet – 59%
  • Obesity – 35%
  • Smoking tobacco – 36%
  • UV light, not just direct from the sun but reflected off shiny surfaces – 54%
  • Blue light from low energy lightbulbs and electronic screens – 29%

More than one in ten people were completely unaware that any of these factors could affect your eyesight at all.
saving vision
72% of respondents own or wear prescription glasses but only 28% knew that there were lenses available (for both prescription and non-prescription glasses) to protect against some of these factors; specifically, blue light from electronic devices and low energy light bulbs, and UV light from direct sunlight and reflective surfaces.

76% admitted they haven’t heard of E-SPF ratings – the grade given to lenses to show the level of protection they offer against UV.

Just 13% have lenses with protection from direct and reflected UV light, and only 2% have protection from blue light (from screens, devices, and low energy bulbs).

Poll results showed that younger people were most aware of the dangers of UV and blue light, yet least aware of how smoking tobacco and obesity can affect your eye health. Within economic sectors, middle to high income people are more aware of the effects of smoking & obesity on eyesight than those with low income –

  • 39% of people with middle to high income compared to 33% of people with low income are aware of the impact of smoking tobacco.
  • 38% of people with middle to high income compared to 31% of people with low income are aware of the impact of obesity.

Awareness of the impacts of smoking and obesity on eye health is significantly higher in Scotland (47% & 49% respectively) than anywhere else in the UK (35% & 33% in England and 40% & 38% in Wales).
Essilor’s Professional Relations Manager, Andy Hepworth, has commented: “The lack of awareness about these common risks to people’s eyes is concerning. Not only would many more glasses wearers be better protected, but also many people who do not wear glasses would likely take precautions too, if made aware of the dangers and the existence of non-prescription protective lenses.”

To see the full results of the poll, please visit the Essilor website.

For more information on the protection offered from blue light and UV through specialist lens coatings, for both prescriptions and non-prescription glasses, please see here for UV & Blue Light Protection options.

*All figures, unless otherwise stated, are from YouGov Plc. Total sample size was 2,096 adults. Fieldwork was undertaken between 21st and 24th August 2015. The survey was carried out online. The figures have been weighted and are representative of all GB adults (aged 18+).

Retinal Vascular Occlusions

Just like any other organ in the body, the retina needs a healthy blood supply to function properly. When a blood vessel in the retina becomes blocked, sudden loss of vision can occur. Such blockages, known as retinal vascular occlusions, often occur in older adults. Because there are effective treatments available, seeing a specialist promptly can prevent further problems or even restore vision.

Retinal arterial occlusions

Arteries are the vessels that bring fresh blood containing oxygen and nutrients to different parts of the body. The artery that supplies the retina is known as the central retinal artery. After it enters the eye, the central retinal artery splits up into branch retinal arteries that serve different areas of the retina.

Symptoms
The symptoms of a central retinal artery occlusion include a sudden, painless loss of vision in one eye. Because the circulation to the entire retina is disrupted, the vision loss is profound and encompasses the entire field of vision. In contrast, a branch retinal artery occlusion only leads to loss of vision in a part of the field of vision. This is because only part of the retinal circulation in compromised. Similar to a central retinal artery occlusion, a branch retinal artery occlusion is also typically sudden and painless.

Evaluation
Retinal arterial occlusions can usually be diagnosed simply by examining the retina. Often, the retina is whitened in the area of the occlusion due to the lack of blood flow. Most arterial occlusions occur in patients with diseases such as high blood pressure or diabetes. On occasion, fragments of cholesterol or blood clots can be cause of the occlusion. Therefore, the treating physician will usually order tests looking for the source of these deposits in the carotid arteries or the heart. Another important cause of central retinal artery occlusions is a condition known as temporal arteritis. Temporal arteritis is an inflammatory disorder that can also produce fever, pain, or weight loss. Blood tests are ordered if temporal arteritis is suspected.

Retinal vascular occlusions
Figure 1. Whitening of the retina due to a central retinal artery occlusion
Treatment
Unfortunately, there is no proven, reliable treatment for retinal arterial occlusions at this time. Various methods including hyperbaric oxygen, ocular massage, and anterior chamber paracentesis may or may not be effective if the occlusion is treated right away. However, if the occlusion is due to temporal arteritis, treatment with corticosteroids is effective at preventing loss of vision in the other eye. An unwanted, late complication of retinal arterial occlusions is neovascularization. Neovascularization refers to the growth of new, abnormal blood vessels in different parts of the eye that can result in bleeding, detachment of the retina, or glaucoma. Neovascularization is treated with laser or injections of anti-neovascular medications into the eye.

Retinal venous occlusions

After blood has passed into the eye through the retinal arteries, it leaves through the retinal veins. Blood travels first through the smaller, branch retinal veins and then enters the central retinal vein.

Symptoms
A central retinal vein occlusion usually causes sudden, painless vision loss in one eye. Unlike a central retinal artery occlusion, which causes profound vision loss, the visual deficit in a central retinal vein occlusion can range from mild to severe. More severe occlusions cause more severe deprivation of vital oxygen to retinal tissue. In addition, a central retinal occlusion can result in macular edema, swelling of the retina that also leads to blurred vision. A branch retinal vein occlusion usually leads to blurring of vision in only part of one eye. Like central retinal vein occlusions, branch retinal vein occlusions can vary in severity, but often result in macular edema as well.

Evaluation
Retinal venous occlusions are also diagnosed by examining the retina. The blocked vein will appear dilated and engorged. In addition, the area of the retina served by that vein will contain hemorrhages or become swollen. To assess the amount of oxygen deprivation to the retina, a specialist will often recommend a fluorescein angiogram. The angiogram involves the injection of a yellow dye known as fluorescein intravenously. Subsequent photos allow visualization of the abnormal blood flow within the retina. In addition, optical coherence tomography is often performed to determine the amount of swelling within the retina.

Figure 2. A retinal vein occlusion with hemorrhages seen as the red spots in the bottom half of the image.
Figure 2. A retinal vein occlusion with hemorrhages seen as the red spots in the bottom half of the image.
Treatment
Treatment of retinal venous occlusions is largely aimed at decreasing swelling in the macula in hopes of improving vision. Currently, the most effective treatments involve injections of medication into the eye. FDA approved medications such as Lucentis and Eylea, that target abnormal levels of growth factors in the eye, can result in significant gains in vision in approximately two thirds of patients with branch retinal vein occlusions and half of patients with central vein occlusions. In addition, injectable steroid medications such as Ozurdex can also be effective, with approximately one third of patients having a significant visual gain. Laser can also be used to treat macular edema due to branch retinal vein occlusions. Keep in mind that these treatments likely need to be repeated on a routine basis or used in combination to achieve maximum benefits. If neovascularization occurs, it is treated as previously described in the section about retinal arterial occlusions.

In conclusion, occlusions of either retinal arteries or veins can cause significant visual impairment. Prompt evaluation and ongoing treatment with a retinal specialist can often improve and maintain vision.

Which Eye Care Specialist Do You Need?

It’s time to get your eyes checked – do you go to an ophthalmologist, optometrist or optician? Your optometrist sees the beginnings of age-related macular degeneration, but is sending you to see and ophthalmologist, why?

One of the most confusing things about taking care of your eyes can be differentiating between an ophthalmologist, optometrist and optician. Each eye care specialist has a very important part to play in the health of your eyes and here is a quick synopsis of what each does so you can choose the best one for your vision issues and treatment.

Ophthalmologist
These specialists are fully trained medical doctors that have completed the eight years of training beyond a bachelor’s degree. Their training has included a full spectrum of eye care, from prescribing glasses and contact lenses and giving eye injections, to carrying out intricate eye surgeries. Many doctors may also be involved eye research to better understand vision, improve eye disease treatments or potentially find a cure. They are easily identified by the MD following their name.

Optometrist
These medical professionals have completed a four-year program at an accredited school of optometry. They have been trained to prescribe and fit glasses and contact lenses, as well as diagnose and treat various eye diseases. They provide treatments through topical therapeutic agents and oral drugs, and are licensed to perform certain types of laser surgery, such as Lasik. They are easily identified by the OD following their name.

Optician
These eye care professionals are not licensed to perform eye exams, medical tests or treat patients. Their purpose is to take the prescription from the ophthalmologist or optometrist and work with you to determine which glasses or contact lenses work best for you. If you suffer from an eye disease like keratoconus, these specialists can make the difference between a relatively normal life, or one that is dictated short periods of vision because of contact lens pain. These eye care professionals may hold and associate optician degree or have apprenticed fore required number of hours.

While each one of these eye specialists has their own area of expertise, they can form a team whose only concerns are your eye health and the ability to see as clearly as possible.

Your Comprehensive Eye Exam

Your Comprehensive Eye Exam

Being able to see clearly is important to all of us. But it is also something we have a tendency to take for granted until we notice changes in our vision. The point of the yearly comprehensive exam is to monitor your eyes before any problems arise, and address any concerns that could affect your vision later. Here is what to expect at your next comprehensive eye exam.

An eye exam involves an external examination of your eyes followed by a series of tests designed to evaluate your vision and check for eye diseases. Each test evaluates a different aspect of your vision and includes specific tests for visual acuity, pupil function, muscle function, visual fields, eye pressure and viewing the back of the eye through a dilated pupil.
cross section of eye - eye exam
External Exam
The external examination consists of inspecting the eyelids, surrounding tissues and the eyeball including the sclera (white part of the eye), iris and cornea.

Visual Acuity & Fields
Visual acuity is your eye’s ability to detect fine details and see an in-focus image at a certain distance. A Snellen chart and a phoropter are used. The standard definition of normal visual acuity is 20/20. The term 20/20 comes from even sized objects that can be seen by a “person of normal vision” atvisual acuity eye exam the specified distance. For example, if a person can see at a distance of 20 feet an object that normally can be seen at 20 feet, then they have 20/20 vision. If they can see at 20 feet what a normal person can see at 40 feet, then they have 20/40 vision. For the visual acuity test each eye is tested separately to gauge your side or peripheral vision.

Pupil Functionpupil function eye exam
An examination of the pupil begins with inspecting your pupils for equal size, regular shape, reaction to light, and direct and consensual reaction (meaning the pupil of one eye constricts when the other eye is exposed to light).

Eye Muscle Function
Eye movement is assessed two ways. First by having you move your eye quickly to a target at the far right, left, top and bottom. Then by slow tracking which uses the ‘follow my finger’ test, which tests all the muscles that move your eye.

tonometer eye examEye Pressure Measurement
Intraocular pressure, or IOP, is measured using a tonometer to determine the fluid pressure inside your eye. This test provides information regarding your potential for glaucoma.

Viewing the Back of the Eyedilated eye - eye exam
Increasing the size of your pupil with eye drops (known as dilating your eyes) allows the doctor to have a larger view of the back of your eye, including the retina, as demonstrated by this diagram. This is very important for diagnosis and tracking of macular degeneration and diabetic retinopathy.

Eye Structureslit lamp eye exam
A special, high-powered microscope, called a slit-lamp, is used to view the structures of your eye clearly and in detail, enabling early diagnosis of a variety of eye conditions such as cataracts, presbyopia and corneal injury.

Taking care of your eyes, especially as you become older, is very important. Changes in vision may be gradual, or fast, but in both cases, early diagnosis is key to successful treatment and retaining your vision. It is suggested that individuals 40 and over have a comprehensive eye exam every one to two years. Exceptions would be if you have diabetes, in which case you should see your eye doctor yearly; or there is a family history of eye diseases such as glaucoma, macular degeneration, or corneal diseases, which may require more frequent visits to your eye doctor. If you have any degree of sudden vision loss, eye pain, or significant irritation, contact your eye doctor immediately.

Do I Need Vision Insurance?

With the rising costs of health insurance, many people are looking for ways to reduce their costs. Since not all insurance packages include vision insurance, many people wonder, do I need vision insurance?
vision insurance

Standard Vision Insurance

Vision insurance is a type of health insurance that entitles you to specific eye care benefits such as routine eye exams and other procedures, as well as a specified dollar mount or discount for the purchase of eyeglasses and contact lenses. It only supplements regular health insurance and is designed to help reduce your costs for routine preventative eye care and eyewear.

You can get vision insurance as part of a group, such as your employer, an association, etc., through a government program such as Medicare or Medicaid, or as an individual. It is often a benefit linked to your regular HMO (health maintenance organization) or PPO (preferred provider organization) health insurance.

There are two primary vision insurance plans available:

  • Vision Benefits Package – provides free eye care services and eyewear within a fixed dollar amount for which you pay an annual premium or membership fee and a small co-pay. It may also include a deductible.
  • Discount Vision Plan – provides eye care and eyewear at a discounted rate after you pay an annual premium or membership fee.

Both insurance plans generally include:

  • Annual eye exams
  • Eyeglass frames (usually once every 24 months)
  • Eyeglass lenses (usually once every 24 months)
  • Contact lenses (usually once every 24 months)
  • Discounted rates for LASIK and PRK

Here is where you can check for a list of some vision insurance providers.

Medicare and Medicaid

Different kinds of vision care are included in the US government programs, Medicare and Medicaid. These programs are for qualifying American age 65 and older, individuals with specific disabilities and people with low income.

The Types of Medicare For Vision:

    • Medicare Part A (Hospital Insurance) –Medical eye problems that require a hospital emergency room attention, but routine eye exams are NOT covered.
    • Medicare Part B (Medical Insurance) – Visits to an eye doctor that are related to an eye disease, but routine eye exams are NOT covered.
    • Medicare Part D (Prescription Drug Coverage) – Will help pay for prescription medications for eye diseases.

If you have Medicare Parts A & B you are generally eligible for the following vision coverage, however, there is a deductible before Medicare will start to pay, at which point you will still be paying a percentage of the remaining costs.

  • Cataract surgery – covers many of the cost including a standard intraocular lens (IOL). If you chose a premium IOL to correct your eyesight and reduce your need for glasses, you must pay for this added cost out-of-pocket.
  • Eyewear after cataract surgery – one pair of standard eyeglasses OR contact lenses.
  • Glaucoma screening – an annual screening for people at high risk for glaucoma, including people with diabetes or a family history, and African-Americans whom are 50 or older.
  • Ocular prostheses – costs related to the replacement and maintenance of an artificial eye.

There is also Medicare Supplement Insurance (Medigap) which is sold by private insurance companies to supplement only Medicare Parts A & B. It is intended to cover your share of the costs of Medicare-covered services including coinsurance, co-payments and deductibles. For more details about Medicare plans and coverage check their website or call 800-633-4227.

Medicaid is the US health program that gives medical benefits to low-income people who may have no or inadequate medical insurance. A person eligible for Medicaid may be asked to make a co-payment at the time medical service is provided. Vision benefits for children under the age of 21 include eye exams, eyeglass frames and lenses. Each state determines how often these services are provided and some states offer similar vision services to adults. To learn more about Medicaid eligibility requirements and vision benefits call your state’s Medicaid agency or visit their website.

Defined Contribution Health Plans

A way to lower your vison care costs is to take part in a defined contribution health plan (DCHP). You are given a menu of health care benefits to choose from where a portion of the fees you receive for health coverage come from money that is deducted from our paycheck before federal, state and social security taxes are calculated. Four types of DCHP are:

Cafeteria Plans – your employer takes a portion of your salary and deposits it into a non-taxable account for health care spending. The amount taken depends on the number and costs of the benefits you select.

Flexible Spending Accounts (FSA) – your employer takes a predetermined portion of your pre-tax salary and deposits it into health care account for you to pay medical expenses. But generally preventative care such as routine eye exams and are not reimbursable. Nor are eyeglasses and contact lenses reimbursable. You would need to verify with your employer. If you do not use all the money at the end of a 12 month period, the money goes back to your employer.

Health Reimbursement Arrangement (HRA) – this is similar to an FSA except you can use it for preventative care like eye exams and you do not lose the money if it isn’t spent within a certain time period as it can be carried from year to year.

Health Savings Account (HSA) – it can be employer-sponsored of you can set up one independently; however you must purchase a high-deductible health insurance plan to open an HSA and you cannot exceed the annual deductible of your health insurance plan. You cannot be enrolled in Medicare of be a depended on someone else’s tax return. You can use it for preventive care such as eye exams. You can learn more about HSAs by visiting the US Treasury’s website.

There are a variety of options when it comes to vision insurance. You just need to determine your needs and ask providers the correct questions.

Medical Research Funding Needs Individual Donors

The Need for Medical Research Funding

About 1.75 million U.S. residents currently have advanced age-related macular degeneration with associated vision loss, with that number expected to grow to almost 3 million by the year 2020.

About 8.4 million individuals worldwide are blind from primary open-angle glaucoma, with that number expected to grow to almost 11 million by the year 2020.

About 22 million Americans have cataracts affecting their vision, with that number expected to grow to more than 30 million by the year 2020.

The economic impact of this increase of people with vision loss will be tremendous.  But right now scientist are working on ways to treat and eventually cure many eye diseases.  The only problem is the funding necessary to support this sight-saving research. Here is a look at the decline of medical research funding in the US and what you can do to help.

It’s All About ME – What to Know About Macular Edema

“You’ve got the macular? I’ve got some but my sister, she’s got all kinds!” Even as the word retina has become commonplace, the macula and its diseases are often feared and misunderstood. The retina is the light-sensitive layer of cells that line the inside of the eye. The many layers of the retina work together to convert what we see into an exquisitely coded signal that travels to the brain. There the message is decoded and directs us to take action – “that’s a fine looking piece of pie!”

The macula is the part of the retina that helps us see fine detail, far away objects, and color. It’s packed with more photoreceptors than any TV or monitor which is why it is prized real estate. It is the small, central area of the retina that’s worth the most – the bullseye of sight. When things happen to the macula, it gets an “r”. Macular edema, macular degeneration, macular hole, pucker, drusen, scar, fibrosis, hemorrhage, and vitreomacular traction are common conditions that involve the macula. When present, distorted vision (metamorphopsia), blank spots (scotoma), and blurred vision are common symptoms.

Four. Ang. - Macular Edema
Figure 1: Fluorescein angiography: Macular edema may be seen as a pinpoint leak (left, large arrow) in mild cases. In serious cases, ME may diffusely involve the macula. Note how the image becomes brighter as more dye leaks from damaged macular capillaries. (Center and Right)

Macular edema refers to an abnormal accumulation of fluid in the layers of the macula. From the side, it looks like the snake that ate the pig. Like a droplet of water on your computer screen, images are distorted by the swollen retina – making it more difficult to see clearly. The more widespread, thicker, and severe the swelling becomes, more likely one will notice visual symptoms. If untreated, chronic macular edema can lead to irreversible damage to the macula and permanent vision loss.

OCT - Macular Edema
Figure 2: Optical Coherance Tomogrphy and Macular Edema: OCT is a useful test to study macular edema (ME)
-The top image has is normal. Note the even layers and gently sloping dip of the macula called the fovea. This eye has excellent vision.
– The middle OCT has ME, black-appearing cysts (arrows) which threaten the normal fovea. This eye also has good vision.
– The bottom OCT shows ME involving the macula. Because ME involves the macular center (the fovea), vision is poor (large red arrow).

Macular edema is not a disease but the result of one. As with other conditions where abnormal fluid accumulates (leg swelling, pulmonary edema, hives, and allergy), macular edema can be caused by many conditions including metabolic (diabetes), aging (macular degeneration), hereditary (retinitis pigmentosa), inflammatory (sarcoidosis, uveitis), toxic, neoplastic (eye tumors), traumatic, surgical, and unknown causes (idiopathic, macular hole, macular pucker, vitreomacular traction). Macular edema occurs when the retina’s ability to keep fluid out of the retina is overwhelmed by the fluid leaking into it. (If more rain falls on the lawn than it can handle, you get puddles of fluid. In the retina, blisters of fluid form and swell the retina – this is macular edema. Fluorescein angiography (Figure 1) and optical coherence tomography (Figure 2) are two common tests to evaluate macular edema.

Macular edema is typically caused by increased leakage or growth of abnormal blood vessels. The most effective treatment strategies address the underlying cause (diabetes, blood vessel occlusion, neovascularization, inflammation, etc) as well as the hyperpermeability of the capillaries in and around the macula. Eye drops, laser, placement of long-acting medication implants, and surgery are effective in many diseases but the mainstay of treatment is now intravitreal injections (IVI). The IVI is an office procedure painlessly performed under topical anesthesia in which medication is placed inside the eye by a very small needle. IVI should be performed by a trained retina specialist with meticulous monitoring of treatment efficacy and of extremely rare but potentially serious complications. IVI is considered one of the most commonly performed procedure in the world.
Lucentis, Eyelea, and Ozurdex are the trade names of the three most common FDA-approved medications for the treatment of the common conditions causing macular edema. Avastin is not FDA approved but has also been extensively studied in large, well-designed, federally-funded clinical trials and is felt to have efficacy and safety no less than any of the other available options. Each option has a considerable track record of success and works by decreasing the amount of fluid leaking from abnormal blood vessels.

Macular edema is a common finding in many diseases of the retina, most which can be treated to improve vision. The physician’s therapeutic armamentarium continues to expand. There has never been a more successful time in the treatment of macular edema and macular disease. While much has been discovered, many promising therapies await.
