Glaucoma Testing and Treatment

What Is a Glaucoma Test?

womanandmicroscope3Glaucoma is the generalized name for a group of eye diseases that damage the optic nerve of the eye, preventing the eye from sending accurate visual information to the brain. Glaucoma tests are designed to test your eyes for one of the key symptoms of the disease—increased eye pressure—however only a comprehensive eye exam at our office in Mobile, AL can reveal whether or not you have glaucoma. Increased pressure inside the eye is often a key indicator of glaucoma, though not exclusively so. Eye doctors can use a number of tests for eye pressure, but will, by default, check for signs of glaucoma as part of a detailed examination of the retina—the light sensitive area at the back of the eye responsible for processing images.

How Does Glaucoma Testing Work?

While increased eye pressure is a key indicator of the disease, it does not necessarily mean you have a glaucoma diagnosis. In fact, the only way to detect glaucoma is to have a detailed, comprehensive eye exam that often includes dilation of the pupils.

So “true” glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease. A Humphrey visual field measures function of the nerve. OCT of the optic nerve measures nerve density. Pachymetry measures corneal thickness. Stereoscopic fundus photos make viewing the depth of the optic nerve possible, making long-term monitoring more effective. Dr. Jackson uses all of these diagnostic tests to manage glaucoma effectively.

Glaucoma Treatment

Depending on the severity of the disease, treatment for glaucoma can involve the use of medications, conventional (bladed) surgery, laser surgery or a combination of these treatments. Medicated eye drops aimed at lowering IOP usually are the firstline of treatment to control glaucoma. Dr. Jackson has been treating and managing glaucoma cases since 1996.
Because glaucoma is often painless, people may become careless about strict use of eye drops that can control eye pressure and help prevent permanent eye damage. In fact, non-compliance with a program of prescribed glaucoma medication is a major reason for blindness resulting from glaucoma.
If you find that the eye drops you are using for glaucoma are uncomfortable or inconvenient, never discontinue them without first consulting your eye doctor in Mobile about a possible alternative therapy.
At Premier Medical Eye Group, we have a fellowship-trained glaucoma specialist that manages the cases that require surgical intervention. Rest assured, no matter how far along a patient presents with glaucoma, we can manage their disease process. All glaucoma surgery procedures (whether laser or non-laser) are designed to accomplish one of two basic results: decrease the production of intraocular fluid or increase the outflow (drainage) of this same fluid. Occasionally, a procedure will accomplish both.
Currently the goal of glaucoma surgery and other glaucoma therapy is to reduce or stabilize intraocular pressure (IOP). When this goal is accomplished, damage to ocular structures – especially the optic nerve – may be prevented or reduced.

Glaucoma can cause slight to severe vision loss, and is often discovered only after the disease is present—that’s why glaucoma testing is so important.
