Avoiding the risk factors for macular degeneration may help prevent it. This includes avoiding tobacco smoke and eating a diet low in saturated fat and rich in antioxidants. Some doctors suggest that wearing UV-blocking sunglasses reduces risk. Use of estrogen in postmenopausal women is associated with a lower risk of developing ARMD. Key Terms DrusenTiny yellow dots on the retina that can be soft or hard and that usually do not interfere with vision. FoveaA tiny pit in the macula that is responsible... more
While vision loss cannot be reversed, early detection is important because treatments are available that may halt or slow the progression of the wet form of ARMD. Some treatments for the dry form were still in early clinical trials in 2001. In wet-type ARMD and in senile disciform macular degeneration, new capillaries grow in the macular region and leak. This leaking of blood and fluid causes a portion of the retina to detach. Blood vessel growth, called neovascularization, can be treated with laser... more
Optometrists and ophthalmologists, with assistance from ophthalmic assistants, technicians and nurses, should carefully screen patients who are at risk for macular degeneration. These include patients older than 60; patients with hypertension or cardiovascular disease; cigarette smokers; patients with a first-degree family (sibling or maternal) history of vision loss from ARMD regardless of age; patients with aphakia or pseudophakia; or someone with a cataract, and patients with a history that indicates... more
Macular degeneration is the progressive deterioration of a critical region of the retina called the macula. The macula is 3-5 mm and is responsible for central vision. This disorder leads to irreversible loss of central vision, although peripheral vision is retained. In the early stages, vision may be gray, hazy, or distorted. Macular degeneration is the most common cause of legal blindness in people over 60, and accounts for approximately 11.7% of blindness in the United States. About 28% of the... more
Older adults who eat diets rich in citrus fruits, leafy greens and fish oil, but low in “glycemic index,” may have a lower risk of age-related macular degeneration, according to a study in the journal Ophthalmology. Read More →
