AGE-RELATED MACULAR DEGENERATION
WHAT IS MACULAR DEGENERATION?
§ A group of progressive eye conditions which involves deterioration of the macula.
§ Age-Related Macular Degeneration (ARMD) is the most common cause of vision loss in the elderly.
§ There are two general types of
ARMD
1. “Dry”, or non-neovascular
§ Early stage, less severe
§ 85%-95% of cases
2. “Wet”, or neovascular
§ More severe
§ Central vision blind spots
HOW IS ARMD DIAGNOSED?
§ If retinal damage is suspected, an eye doctor will perform a retinal exam.
§ Fluorescein angiography is used to examine the retinal blood vessels.
§ Amsler grid (a card with horizontal and vertical lines which look wavy or have missing sections if you have ARMD.)
§ In “Dry” yellowish spots or drusen form on the retina.
§ In “Wet” unwanted blood vessels leak blood and fluid beneath the retina.
WHAT IMPACT DOES ARMD HAVE ON YOUR VISION?
§ Loss of sharp, central vision (fuzzy or shadowy vision)
§ Distorted vision
§ Difficulty seeing fine detail
§ Difficulty seeing color
COMMON TREATMENTS
§ There is no cure for “Dry” or “Wet” ARMD at this point in time.
§ No FDA-approved treatments exist for “Dry” ARMD.
§ Studies indicate taking vitamins A, C, and E, zinc, lutein, antioxidants, & Omega-3 oils may help prevent or slow “Dry” Macular Degeneration.
§ Various FDA approved drugs are used to slow down the progression of “Wet” ARMD.
· Lucentis, Macugen
· Visudyne used with Photodynamic Therapy or PDT
HOW DO YOU OR YOUR LOVED ONE ADAPT TO THIS CONDITION?
§ Low vision aids such as magnifiers
§ UV protected sunglasses
§ Proper lighting for near tasks
§ Regular visits to your ophthalmologist or optometrist
