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.
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.
We are pleased to be able to provide the latest cutting-edge technology in retinal imaging. Optos is an ultra-widefield imaging system that allows us to photograph a 200-degree view of the back of your eye (retina) without dilation. It is crucial in obtaining these photographs in diagnosing and monitoring macular degeneration. The software included provides special filters that enable the smallest changes to be identified.

Early AMD: note the yellow drusen deposits
Advanced DRY AMD
End Stage AMD (Geographic Atrophy
Zeiss 6000 OCT is the newest technology that takes 100,000 scans per second of the structures beneath the surface of the macula. further enhancing our ability to diagnose and monitor AMD. By evaluating the underlying layers of the macula, it gives us the ability for a very early diagnosis tha could otherwise go undetected. This instrument has the unique ability to assess if the macular degeneration is converting from DRY AMD to the more severe forms of either Geographic Atrophy or WET AMD. Early identification and treatment of these more severe forms are essential in obtaining a better outcome.

This is the only technology that can diagnose macular degeneration (AMD) up to 3 years BEFORE it shows up in a regular eye exam. The cells in your eye that help you see in the dark (called rods), are the first part of the eye that is affected by Macular degeneration. This test has the concept of walking into a dark theater from the outside. Your eyes take a minute or so to adjust, and then you can begin to see in the dark.
With macular degeneration, the ability of the eye to adjust quickly from light to dark is impaired. The Adapt Dx test measures the number of minutes it takes your vision to adjust to the darkness and compares it to the normative database.
The end result is known as the Rod Intercept (RI). If the RI measures greater than 6.5, then that is indicative of underlying macular degeneration. If that occurs, then it is recommended to return for an extended version of the test to get a baseline reading so as to be able to monitor any future progression,
If it is determined that you have early signs of macular degeneration, lifestyle changes are recommended as follows.
STOP SMOKING: #1 risk factor that can slow up AMD progression
Increase intake of dark greens and fish such as spinach, kale, broccoli, and salmon
Maintain good cholesterol and blood pressure readings
Quality sunglasses with Ultraviolet A and B protection
Addition of specific eye vitamins containing Lutein and Zeaxanthin
This test should be performed if:
You have noticed a harder time with night vision
Over 50 and family history of AMD (There are easy genetic tests that can determine if you have the AMD gene)
Been told macular changes were noted in your exam
Patients are given an Amsler Grid to self check at home. Any distortion or blank areas of the grid indicate progression of the disease and should be promptly relayed to the doctor.
