OPTICAL COHERENCE TOMOGRAPGY (OCT)

The Optical Coherence Tomography (OCT) test is a safe, quick, and non-invasive eye scan used to help detect and monitor glaucoma. Glaucoma is an eye condition that damages the optic nerve, often due to high eye pressure, and can lead to vision loss if not treated early. It uses light waves to take detailed images of the structures at the back of your eye, especially the optic nerve and the layers of the retina. These images show the thickness of the nerve fiber layer and help your eye doctor see if there is any damage from glaucoma or if the condition is getting worse over time
The test usually takes just a few minutes. You will sit in front of the OCT machine and rest your chin and forehead in place. You will be asked to look at a target light while the machine scans your eyes—there is no discomfort, and nothing touches your eye. If you have glaucoma or are at risk, regular OCT scans can help protect your sight by catching the disease early.
