OCT-Optical Coherence Tomography

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

What conditions can OCT help to diagnose?


Optical coherence tomography (OCT) is useful in diagnosing many eye conditions, including:
• Macular hole;
• Macular pucker;
• Macular edema;
• Age-related macular degeneration;
• Glaucoma;
                                                                                               •  Diabetic retinopathy;
                                                                                              •  Membranes.


In addition, OCT is often used to evaluate disorders of the optic nerve. The optic nerve is made up of many nerve fibers and sends signals from your retina to your brain, where these signals are interpreted as the images you see. The OCT exam is helpful in determining changes to the fibers of the optic nerve, such as those caused by glaucoma.

Since OCT relies on light waves, it cannot be used successfully with any condition that interferes with light passing through the eye, such as dense cataracts or significant bleeding in the vitreous (the gel in the center of the eye).
