Macular Degeneration

Macular Degeneration

At Primary Eyecare and Eyeware, we are a Center of Macular Degeneration and offer state-of-the-art technology to allow for early diagnosis and intervention of macular degeneration

Macular degeneration, commonly referred to as age-related macular degeneration (AMD), is the single largest cause of sight loss in the developed world and affects more than 10 million Americans. It usually affects people over the age of 60, but has been known to affect those who are younger. It is a painless condition that usually affects both eyes with the loss being experienced in the central vision. It does not affect the peripheral vision, meaning that it does not cause total blindness.

What is the macula?

The macula is the most sensitive part of the retina and is responsible for our central vision and what allows us to see fine details with clarity.

Varieties of AMD



Wet AMD is one variety of the condition in which abnormal blood vessels grow into the macula, leaking blood or fluid which then causes scarring and a rapid loss of central vision. Wet AMD can develop suddenly and rapid referral to a specialist is essential as it can be treated if caught quickly.


Dry AMD is the most common variety of age-related macular degeneration and is a gradual deterioration of the retina as the cells die off over time and are not regenerated. Up to 15% of people with dry AMD go on to develop wet AMD, and so any sudden changes in your vision should be followed up with your optometrist as soon as possible.

Symptoms of macular degeneration

Macular degeneration affects each person differently, which means that it can sometimes be difficult to diagnose, particularly as you may not notice any change in your vision early on in the condition. However, as the cells deteriorate, you will start to see an increasing range of symptoms, including:

  • Distortion or bends in what should be straight lines (such as lampposts or door frames)

  • Dark spots in your central vision

  • Fading colors

  • Difficulty adapting from dark to light environments

  • Blurred vision

  • Objects may appear to change shape, size or color, or may move or disappear

  • Bright lights may be difficult to tolerate

  • Words may disappear while you are reading


Is there any way I can reduce my risk of developing AMD?

Unfortunately, there is no clear reason as to what triggers the process that causes macular degeneration. However, you are at an increased risk if you have a family history of the condition, or if you are over 60. 

Experts suggest that the best thing you can do to minimize any potential risk is to ensure that you live a healthy, active lifestyle. You can do this by:

  • Stopping smoking

  • Eating a healthy, balanced diet with plenty of fruit and vegetables

  • Moderating your alcohol consumption

  • Maintaining a healthy weight

  • Getting regular exercise

There is also some limited research that suggests that eating leafy, green vegetables can slow the deterioration of vision in cases of dry AMD.

Treatment for AMD

Sadly, there is currently no cure for either variety of AMD. In the case of dry AMD, the treatments suggested are done so with the aim of aiding the patient to make the most of their remaining vision. This can include things such as using magnifying glasses to help with reading.

Wet AMD can be treated with anti-vascular endothelial growth factor medication. This should stop additional blood vessels from developing and stop your vision from deteriorating further.

Occasionally, laser therapy is suggested as a possible treatment for destroying abnormal blood cells, but this is only suitable for cases of wet AMD and usually only around 1 in 7 sufferers may be potential candidates for this procedure.

We have cutting-edge technology - the AdaptDx for detection of pre-clinical macular degeneration. We recommend AREDS2 supplements from EyePromise for patients who are at risk of macular degeneration or have macular degeneration.

The AdaptDx is a specialized instrument used to quantify a patient’s dark adaptation time:  the time needed to adjust your eyes from light to dark, and dark to light.  This is important because decreased dark adaptation time has been determined to be a biological marker for early, pre-clinical, macular degeneration. We offer a free screening to all patients over the age of 60 at the time of their exam, taking about 5 minutes of their time.  It is a painless, artificial intelligence driven test, that patients can easily understand.  Patients who do not pass the screening test are asked to come back to the office at a later date for a more advanced (longer) version of the screening test.  The results of the advanced AdaptDx are the guideline for the next steps in treatment for the patient.  These steps usually include a quarterly or biannual follow up and the start of EyePromise AREDS2 twice daily.

These are the brand supplements (commonly referred to as vitamins) that our office recommends for patients to begin when they have been shown to have pre-clinical macular degeneration (detected by the AdaptDx), or if they have the signs of early clinical dry macular degeneration, or if they have  a strong family history of macular degeneration.  AREDS (Age Related Eye Disease Study) were formulated a few decades ago as a result of the extensive study of patients with the disease.  The ingredients in the supplement support your aging eyes.  These vitamins include natural ingredients proven to increase your eyes’ natural protective macular pigment and strengthen your retinal blood vessels and tissue.   

If you have any questions or concerns regarding macular degeneration, we highly recommend that you speak with your optometrist who will be happy to assist you.
