Optical Coherence Tomography Analysis is much like Ultra-Sound, except that it uses light instead of sound This instrument is able to make 3-dimensional images of the Retina. The layers that make up the retina are easily visualized, the location of any abnormalities within the retina can then be identified. Eye conditions, for example Central Serous Retinopathy, Glaucoma may be diagnosed and monitored.

Picture on the right shows the layers of the retina, The dip in the center is the Fovea, the most sensitive area of the retina. this is your central fixation spot. images projected here is the sharpest. Look towards the left of picture A. notice that a separation of the layers has occurred. this is Central Serious Retinopathy which may be difficult to pick up from a picture of the retina.
