Eyecare Glossary

OCT is a non-invasive imaging technique used in optometry to capture high-resolution cross-sectional images of the retina and other ocular structures. It employs light waves to create detailed images of the eye's internal structures, similar to ultrasound but using light instead of sound. OCT is particularly useful in diagnosing and monitoring eye conditions such as macular degeneration, glaucoma, and diabetic retinopathy, as it provides valuable information about the thickness and integrity of various eye tissues.
