Dr. David Ardaya, O.D., California Optometric Association, shares the following article on glaucoma — a leading cause of blindness in the United States — in honor of National Glaucoma Awareness Month.
The disease has virtually no early warning signs, cannot be prevented and may take vision at a moment’s notice. Learn more about the condition.
Glaucoma is a group of eye disorders leading to progressive damage to the optic nerve. It’s characterized by loss of nerve tissue resulting in loss of vision. The optic nerve is a bundle of about one million individual nerve fibers and transmits the visual signals from the eye to the brain.

The most common form of glaucoma, primary open-angle glaucoma, is associated with an increase in the fluid pressure inside the eye. This increase in pressure may cause progressive damage to the optic nerve and loss of nerve fibers, often resulting in vision loss and even blindness in advanced stages.
Not everyone with high eye pressure will develop glaucoma, and many people with normal eye pressure will develop glaucoma. When the pressure inside an eye is too high for that particular optic nerve, whatever that pressure measurement may be, glaucoma will develop.
According to the American Optometric Association (AOA), certain factors can increase the risks of glaucoma including:
Only regular comprehensive eye exams can protect your vision from glaucoma. By enabling optometrists to diagnose the disease at an early stage, comprehensive eye exams play a critical role in successful outcomes for patients. Anyone can visit the American Optometry Association’s website to find a local doctor or their state optometric association.
The treatment of glaucoma is aimed at reducing intraocular pressure. The most common treatment of glaucoma is usually prescription eye drops that must be taken regularly. In some cases, systemic medications, laser treatment or other surgery may be required. While there is not yet a cure for glaucoma, early diagnosis and continuing treatment can preserve eyesight.
Patients with glaucoma need to continue treatment for the rest of their lives. Because the disease can progress or change silently, eye medications and eye examinations are essential, as adjustments may need to be made every so often.
