Optical Coherence Tomography

Scan for diagnosing age-related macular degeneration, glaucoma, and diabetic eye disease

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-sectional scans of your retina, the light-sensitive tissue lining the back of the eye.

With OCT, each of the retina’s distinctive layers can be seen, allowing your doctor to map and measure their thickness in micron values.  These measurements help with diagnosis and provide treatment guidance for glaucoma and other retinal diseases, such as age-related macular degeneration and diabetic eye disease.
