Optical Coherence Tomography
OPTICAL COHERENCE TOMOGRAPHY (Zeiss Stratus OCT)
Laser scanning of the retina with our Zeiss Stratus Optical Coherence Tomographer enables cross sectional imaging of the retina and optic nerve. This can be compared to a CAT or CT scan used to give cross sectional images of the brain. The difference is that this instrument uses a non invasive laser light instead of x rays to obtain an image. The procedure takes only a few minutes and is completely painless. During the procedure the patient is seated behind the instrument and asked to maintain fixation at a small light inside the instrument. While the patient is looking at the target the laser scans the retinal tissue in a matter of seconds. The digital color image obtained allows us to visualize abnormalities or structures within the retina down to less than 10 microns. This procedure is very helpful measuring nerve damage in glaucoma. Retinal changes in diabetes, macular degeneration, central serous retinopathy, cystoid macular edema, epiretinal membranes, hypertensive retinopathy, and other conditions are also able to be managed more accurately than ever before.
As part of 20/20's commitment to excellence in vision care, we provide:
• Treatment of complications from eye infections, ocular allergies, and dry eyes.
• Custom contact lens fitting for astigmatism, bifocals, sports; as well as specialty fits for keratoconus.
If you have any questions regarding any procedure, we're here to provide you the answers.
