Optical Coherence Tomography - OCT

How the test is performed:

• After dilation of the eye, the patient sits in front of a machine and stares at a greenish blinking dot. A light scanner of varying patterns scans appropriate portions of the patient’s eye. The technician ensures the test quality is of an appropriate standard. The patient may be asked not to blink for brief periods. There is a mild flash, but no pain. Each eye is usually scanned at least four times or more using various scanning methods. Patients do not usually report feeling pain, though some feel unsettled by the flash of the strobe after each scan. The test runs approximately 10 – 15 minutes.

• The OCT machine immediately produces reports for review by the physician.
