Nerve Fiber Analysis by Stratus OCT (Optical Coherence Tomography) A non-invasive test for nerve damage from glaucoma
One-to-One EyeCare is proud to offer non-invasive testing for glaucoma patients using state-of-the-art technology called “Optical Coherence Tomography.” In the office, we refer to this test as a “Nerve Fiber Analysis” test, or an “NFA” and the machine we use is the Stratus OCT.

Earlier detection allows earlier treatment
Glaucoma is a condition in which decreased blood flow to the optic nerve, the large bundle of nerve fibers which carry vision signals from the eye to the brain. While the most common form of glaucoma has no symptoms, it can gradually cause a loss of side vision or “peripheral” vision. If not detected early and treated properly, the side vision loss can progress to total blindness. When caught early and treated, glaucoma need not cause any noticeable vision loss. Nerve Fiber Analysis with the Stratus OCT can usually pick up signs of optic nerve damage long before there is any loss of peripheral vision, helping us to detect and treat glaucoma at the earliest possible stage.

Images with microscopic detail using only a light beam
Optical coherence tomography is a painless in-office test that takes just a few moments. You look into a computerized camera-device that scans the inside of your eye with light. The camera contains sensors which detect the light that reflects off of the retina and optic nerve. The camera filters out scattered light and processes only the unscattered light, providing a detailed image of the multiple layers of the retina including the top layer of optic nerve fibers. The image reveals microscopic detail using nothing but harmless visible light.

A useful way to monitor glaucoma patients
Nerve fiber analysis by OCT is a very sensitive way to detect early nerve damage from glaucoma and to monitor for any worsening of optic nerve fiber damage in patients already being treated for glaucoma. If the OCT detects progression, we can prescribe additional treatment for the glaucoma in the form of drops, laser treatment or surgery.

It also helps detect many retinal abnormalities
Optical coherence tomography can also be used to look at the retina for signs of swelling, macular degeneration and a variety of other abnormalities of the retina. It is an important at One-to-One EyeCare and another example of our use of advanced technology to meet your eye care needs.
