Sight Unseen: Glaucoma Takes Sight without Warning

Glaucoma begins by attacking peripheral vision, typically causing objects to appear less clearly. At first, it is possible to compensate by squinting or turning the head to focus better. But be careful. These changes may seem minor, but glaucoma can accelerate quickly; causing eyesight to rapidly and irreversibly deteriorate.

Like many diseases, some factors can increase the risk of developing glaucoma, such as age, race or genetics.  Glaucoma usually affects one in 200 people by age 50, but as many as one in 10 people by age 80.  The risk of developing glaucoma is much higher among African Americans: four to five times higher.  In fact, glaucoma is the leading cause of blindness in African Americans.  Not only do African Americans usually develop glaucoma 10 years earlier than Caucasians, they are also six to 15 times more likely to be blinded by the disease.

Glaucoma cannot be prevented, but if diagnosed and treated early, it can be controlled.  This reinforces what the National Optometric Association and the AOA already recommend: adults need regular, comprehensive eye exams.  Fortunately, Medicare covers annual glaucoma screenings for people considered at heightened risk of developing glaucoma, such as individuals with diabetes, those with a family history of glaucoma, African Americans age 50 and older and Hispanic Americans age 65 and older.

So start off the new year right: set up an appointment with your eye doctor – and maybe hit the gym and grab a salad on your way home.

Medicare patients at high risk for glaucoma can receive dilated eye examinations as a benefit of Medicare coverage. Currently eligible beneficiaries are individuals with diabetes mellitus, individuals with a family history of glaucoma, Hispanic-Americans age 65 and over, and African-Americans age 50 and over. matches patients with participating optometrists in their area.
