Optical Coherence Tomography
Optical Coherence Tomography (OCT) uses a noninvasive safe beam of light with special computerized processing to look at the structures within the retina in very high detail. It basically allows us to perform a noninvasive “virtual biopsy” of the retina. Seeing the retina from this cross sectional viewpoint provides a powerful way to detect, diagnose, and treat retinal disease. Pathological changes associated with age-related macular degeneration, diabetic macular edema, central serous chorioretinopathy, choroidal tumors and macular edema associated with retinal vein occlusions can be detected and monitored with this form of imaging. OCT imaging is also a key component in the diagnosis and follow-up of glaucoma with scans designed to calculate changes to the optic nerve and surrounding nerve fiber layer.
