Optical Coherence Tomography (OCT)


   Optical coherence tomography (OCT) uses near-infrared light to provide direct cross-sectional measurement of the RNFL (retinal nerve fibre layer): which is the earliest change found in glaucoma The principles employed are similar to those used in B-mode ultrasound except light, not sound, is used to produce the 2-dimensional images. The light source can be directed into the eye through a conventional slit-lamp biomicroscope and focused onto the retina through a typical 78-diopter lens. This system requires dilation of the patient’s pupil.
