High-Resolution Optical Coherence Tomography

At Sharnam Eye Centre & Laser Services, we are proud to offer our patients the latest in optical coherence tomography (OCT) technology.

OCT works essentially like an ultrasound, but instead of using sound waves, OCT uses light waves to obtain higher resolution and magnification than what is possible with ultrasound. We perform OCT scans of the macula to obtain a magnified view of the full thickness of the macula (that is, an optical “slice” through the macula). You doctor studies the images of your macula to determine the presence of conditions such as macular edema, macular pucker, and macular hole, to name a few. Repeat OCT scans are sometimes needed to follow the response to treatment. With OCT technology, your doctor will be able to detect tiny amounts of leakage and other abnormalities in the macula that are too small to be seen by examination alone.

What to expect  OCT is rapid, painless and non-invasive. You will be seated comfortably and instructed to place your chin in a chin-rest on the machine. You will then be instructed to look at a target inside the machine while the images are obtained. The entire process takes only a few minutes. Your doctor will review the results with you in the examination room.
