Optical Coherence Tomography in Macular Disorders


In ultrasound, a high frequency sound wave is launched into the eye with the help of a probe and the sound wave is reflected from different boundaries between microstructures. However, the OCT uses light rather than ultrasound. The speed of the light is almost a million times faster than sound and this difference allows the measurement of structures with resolution of =10 μ compared to 100μ scale for ultrasound. Secondly OCT does not require contact like the ultrasound.
