Let’s discuss Macular Degeneration. The incidence of Macular Degeneration in the United States in people over 40 years of age is about 1.5%. There are two main forms of macular degeneration associated with ageing: Wet and Dry Macular Degeneration. Macular Degeneration results in injury to the most sensitive part of the retina, that changes light to vision, in the one area of the eye that can perceive the smallest details. People with Macular Degeneration may notice distortion where straight lines appear wavy and irregular. There may be Scotomas where they don’t see anything at all. Patients may look at an Amsler Grid, which looks like a piece of graph paper, each day. When new distortion is noticed, patients should see their Ophthalmologist immediately to detect and treat any possible Wet Macular Degeneration and rule out other causes of distortion. Wet macular degeneration is less common than dry macular degeneration. In Wet Macular degeneration an abnormal growth of blood vessels in retina, results in protein and blood leakage, scarring, and loss of the ability to see small details. Wet Macular Degeneration, is now treated most commonly with injections in the eye of substances, such as Avastin and Leucentis that cause the abnormal blood vessels to regress, stop leaking, and to not further injure the retina. In Dry Macular Degeneration, vitamins are prescribed to prevent deterioration of the Macular Photoreceptors. Macular degeneration may be aggravated by exposure to ultraviolet radiation. Protective eyeware may help eliminate exposure to ultraviolet radiation.
