Optical Coherence Tomography definition
Optical Coherence Tomography (OCT) – an imaging procedure that noninvasively and painlessly permits the ophthalmologist to visualize the layers of the RETINA.
OCT can provide a “virtual biopsy” of retinal tissue, helping diagnose or monitor AGE-RELATED MACULAR DEGENERATION (ARMD), macular holes, retinal tears, and OPTIC NERVE inflammation or damage such as can result from GLAUCOMA. The ophthalmologist can perform OCT in the office; no preparation or recovery is necessary.
