Optic Nerve Analysis

The high eye pressure associated with glaucoma can damage your optic nerve before you begin to experience any vision loss. The Heidelberg Retinal Tomograph (HRT) analyzes three important structures of the optic nerve -- the cup, the rim and the retinal nerve fiber layer (RNFL) -- to detect damage before symptoms manifest. This invaluable collection of data allows Dr. Mang to diagnose glaucoma, check the progress of the disease, and identify high- and low-risk patients.

When you undergo optic nerve analysis, you'll sit at the machine, cover one eye and center your pupil in front of the camera. The technician presses a button and the machine takes pictures of the nerve in the back of your eye. The procedure is painless. All you see is a series of flashing red lights.

Visual Field Test

By the time you notice a loss of peripheral vision, 50% of your optic nerve has probably been destroyed. This makes it doubly important to undergo regular optic nerve analysis. It also means that peripheral field testing equipment needs to be highly sensitive.

The Humphrey^® Field Analyzer is the gold standard in glaucoma diagnosis and management based on peripheral vision quality. Its sophisticated software compares your measurements with data from patients around the world to detect and quantify glaucoma progression automatically and also to identify patients at high risk of developing the disease.

In addition to this unparalleled feature, the HFA reduces test time to a few minutes. And it allows us to save your records electronically, so they can be stored and compared to the results of your next test.

We recommend that patients who have glaucoma come in for the visual field test once a year to check for progression of the loss of peripheral vision.
