About Glaucoma Surgery
Are you experiencing problems with your peripheral or side vision? Do you have to turn your head to see what's to your immediate right or left? Do you have blurred vision, nausea, and headaches? Do you see "halos" around bright lights? It might be glaucoma. Glaucoma is a group of eye diseases that can lead to blindness by damaging the optic nerve. The eye continuously produces a fluid, called the aqueous, that must drain from the eye to maintain healthy eye pressure.
What You Can Expect:
In the most common type of glaucoma, Primary Open Angle Glaucoma, the eye's drainage canals become blocked, and the fluid accumulation causes pressure to build within the eye. This pressure can cause damage to the optic nerve, which transmits information from the eye to the brain. Glaucoma results in peripheral (or side) vision loss initially, and the effect can be like looking through a tube or into a narrow tunnel. This "tunnel vision" effect makes it difficult to walk without bumping into objects that are off to the side, near the head, or at foot level. Glaucoma is an especially dangerous eye condition because most people do not experience any symptoms or early warning signs at the onset of glaucoma. This is why glaucoma is often called "the sneak thief of sight."
Glaucoma Can Be Treated, Not Cured
Glaucoma can be treated, but it is not curable. The damage to the optic nerve from glaucoma cannot be reversed. However, lowering the pressure in the eye can prevent further damage to the optic nerve and further peripheral vision loss. Early detection, appropriate and ongoing treatment, and the availability of specialized low vision and vision rehabilitation services can help people with glaucoma live productive and satisfying lives. Starting as early as age 35, an eye pressure check for glaucoma should be an essential part of your annual routine eye examination. A visual field test will detect peripheral vision loss.
