Abstract

Optical Coherence Tomography (OCT) is new technique that produces images of biological tissue by measuring the reflection of light from the structure being examined. OCT can greatly assist clinicians in diagnosing and managing glaucoma, especially early disease, when used in conjunction with serial clinical exams and visual field testing. Identification of structural damage to the optic nerve and retinal nerve fiber layer (RNFL) is an important component in the diagnosis of glaucoma. Spectral Domain OCT (SD-OCT), allows an earlier examination of these structures and is equipped with an analysis of the macula area to detect ganglion cell damage.
