Optical Coherence Tomography

OPTICAL COHERENCE TOMOGRAPHY (OCT) is a non-invasive tests used by ophthalmologists and retina specialists to measure the thickness of the retina in cross-section. 

 

Why are OCT tests performed?  The OCT test is a quick, painless way for your doctor to determine whether there are any structural abnormalities of the retina, or whether blood vessel within or behind the retina are leaking more than they should.  Information for this test is valuable to your doctor in diagnosing and treating many common diseases of the retina, including epiretinal membrane, macular hole, macular degeneration, diabetic retinopathy, retinal vein occlusion, and central serous retinopathy.

 

How does this test occur?  After your pupils are dilated, the technician will ask you to sit at the OCT machine with your chin on a chin rest and gaze at a blinking light.  Light waves from the machine will scan across your retina, and produce an image for your doctor to interpret.  The test takes about 5 minutes for both eyes.

 

Are there side effects?  Temporary blurred vision is uncommon and mild.
