Images of the Nerve fiber layer, here emphasized in shades of yellow, orange and red, contrast with the blue-purple areas of the retina that have thinner layers. By evaluating the thickness of the layer, and comparing it to normal controls, as well as sequential examinations of each patient, the progression, or absence of progression can be used to monitor and adjust medical, laser or surgical treatment. Studies have shown that nerve fiber layer damage can be demonstrated years before there is any other evidence of glaucomatous damage.
Optical coherence tomography (OCT) is a new modality to further diagnose optic nerve and fiber layer abnormalities. OCT can accurately diagnose the earliest signs of glaucoma, as well as aid in diagnosis and management of retinal diseases.
Call our office to arrange for your nerve fiber layer analysis. If you are over fifty, or have a family history of glaucoma, or of African-American descent, you are at added risk for glaucoma. Keep in mind that no one single test can completely diagnose glaucoma, and it is only by careful examination, including intraocular pressure and visual fields, among other tests, that we can adequately evaluate you ocular health.
Once a diagnosis of glaucoma is made, there are several ways of treatment. Eye drops are effective, but various laser procedures may also be beneficial. Learn about SLT (Selective laser trabeculoplasty)
The OCT is used as well in diagnosing and treating retinal diseases, such as macular degeneration, diabetic retinopathy, and various vascular disorders of the eye.
