Abstract

Optical coherence tomography (OCT) is a low -coherence, interferometer-based, noninvasive medical imaging modality that can provide non-contact high resolution, cross sectional images of biological tissue. Use of OCT in posterior segment of eye was first reported by Hang et al in 1991(1). Since then it has revolutionized the way ophthalmologist diagnoses certain eye diseases especially macular diseases. This is in large part due to its technical ease of use, quick and patient friendly just like taking a photograph. It plays giant role in identifying, monitoring and quantitavely assessing diseases of macula and Optic nerve head. It is invaluable and excellent education tool for patient particularly in macular diseases since the abnormalities may be subtle on fundus photographs.
