Early Detection is Critical to Treating Glaucoma
Glaucoma is a major cause of vision loss worldwide. It affects more than 3.5 million people in North America—nearly half of whom are unaware they have the disease. During Glaucoma Awareness Month in January, Cornerstone Optometry joins the American Academy of Ophthalmology (AAO) in reminding the public that early detection and treatment can help protect your sight.
Glaucoma damages the optic nerve, which transmits visual information from the retina to the brain. Typically, the disease initially has no signs or symptoms. If left untreated, glaucoma can cause irreversible blindness. A comprehensive eye exam provides an opportunity to carefully examine the eye including the optic nerve for signs of damage and other possible problems that may affect vision. Individuals at greater risk for developing glaucoma include people:
over age 40;
of African, Asian or Hispanic heritage;
who have high eye pressure detected during an eye exam;
who have experienced eye trauma or eye injury;
whose corneas are thin in the center;
or who have health problems such as diabetes, migraines, high blood pressure or poor blood circulation.
Appropriate treatment for glaucoma depends on the specific type and severity of the disease. Medicated eye drops or laser treatments are the most common initial approach. These techniques work by lowering eye pressure to reduce the amount of fluid in the eye, and by increasing fluid outflow from the eye.
“Glaucoma is typically symptomless to patients; however, permanent, irreversible vision loss can already be taking place,” said Andrew G. Iwach, M.D., a clinical spokesperson for the American Academy of Ophthalmology. “Early detection is paramount to avoiding blindness and managing this disease.
