Retinal OCT Analysis

Many retinal diseases now have treatments that can help restore, or at least preserve vision.

Usually diagnosis and treatment decisions for these diseases are based on the doctor looking at eye carefully through a microscope. Although these observations are very useful, they do not provide all the information that retinal OCT retinal mapping can provide.

With a Fourrier Domain Ocular Coherence Tomogram (OCT), light interferometry is used to obtain high definition (5 micron) images to analyze the part of the retina used for central vision; the macula.

This helps Dr. Lane determine:

• When treatment is necessary
• When treatment should be modified

The OCT is not a laser, and is not harmful to the eye. The test is safe, and takes about 15 mins to complete; the patient looks at a light target, and is asked to blink or move the eye from time to time. Dilating drops are needed about 10% of the time, so for the first scan, it is best to come with a driver.
