Retinal Nerve Fiber Layer Analysis

The optic nerve is essentially a cable composed of over a million nerve fibers. Recent advances in technology permit measurement of characteristics of the nerve fibers that make up the optic nerve. Changes in the nerve fibers themselves may predate changes in the overall appearance of the optic nerve. By analyzing these nerve fibers, we hope to identify glaucoma progression at earlier stages in an effort to arrest glaucoma damage before it may cause vision loss. Examples of machines that provide information regarding the retinal nerve fiber layer are: GDx, HRT, and OCT.
