“Preserving our vision means preserving our independence.” Jan Fowler couldn’t have said it better, as we rely so much on our eyes as we take in the world around us. In the March issue of “Not Born Yesterday!”, Jan’s column “Senior Moments” discusses the importance of eye care and the warning signs of common eye conditions often faced by seniors: Cataracts, Glaucoma, and Macular Degeneration.
Typically related to aging, Cataracts are the opacification of the normally clear lens of the eye; the lens must be kept clear in order for the retina to receive an image which is sharp. Warning signs include poor night vision, blurred cloudy vision, glare or halos around light sources, vision with brownish tint, and double vision. Treatment may include a low saturated low-fat diet, UV blocking sunglasses, drinking lots of water, and other remedies.
Glaucoma is a wasting of the optic nerve which can result from high eye pressure, injury, low blood flow to the optic nerve, and perhaps certain chemicals that contain glutamine. The most common form is Open-Angle Glaucoma, and does not present noticeable symptoms at first. Warning signs include loss of peripheral vision, light sensitivity, headaches, nausea, cloudy or haloed vision, one eye larger than the other, vision loss, and excessive blinking. Eye doctors have many tests and treatments for Glaucoma, however, including eye drops, oral medications, or surgery. The ultimate goal in Glaucoma management is to preserve the optic nerve, and people 45 years and older (or who have a family history of glaucoma) are encouraged to get an eye checkup every two years.
Macular Degeneration is the loss of retina receptors in the center of the retina (called the macula). Since the macula is the most reactive part of our body, it is constantly bombarded by light. The most common is the dry form, which is treated with nutrition and vitamin supplements. Sunglasses and plenty of sleep are also recommended. Warning signs of Macular Degeneration include occasional blurred or fluctuating vision, difficulty reading or driving, flickering lights, and the need for additional light while reading. While peripheral vision is typically satisfactory, central vision is often affected. However, some patients with dry AMD may not experience visual symptoms at all.
Jan recommends all seniors to visit their doctor for annual eye checkups, taking care to make more frequent appointments if family history places them at higher risk for such conditions.
