Optical Coherence Tomography
Optical coherence tomography (or “OCT”), is a non-invasive test that uses light waves to provide a cross sectional image of important structures in the back of your eye. These structures include your retina (the layer at the back of your eye that detects light), and your optic nerve (the nerve that transmits the light detected, back to your brain). Being able to see the different layers behind your eye is very valuable in diagnosis and management of various eye diseases. Some common conditions that can be diagnosed and managed through the use of OCT include glaucoma, diabetic retinopathy, age-related macular degeneration, and other conditions that might cause swelling of the optic nerve or retina.
