Spectral Domain Optical Coherence Tomography (SD-OCT)
How is the exam performed?
The OCT is rapid and non-intrusive. There’s no pupil dilation or discomfort. You simply lean into the instrument and look at a visually comfortable light. A safe laser scans the back of your eye and acquires an image in less than one second. Exam times can take less than 1 minute!
The OCTis a significant breakthrough over existing tests. The standard pressurecheck (tonometry) is ineffective for detecting glaucoma in a significant percentage of individuals. Visual field testing (perimetry) is limited to measuring vision already permanently lost to glaucoma. The OCT provides precision data to assist your doctor in determining if you have glaucoma. These images and other information about your eye are compared to an extensive database to determine how your eye compares to healthy eyes and those with glaucoma.
The OCT can also give a detailed scan of the macula to help detect macular degeneration, diabetic macular edema, and other macular problems much earlier than was possible in the past.
Many insurers cover the OCT, including Medicare. Call our office about coverage if you have questions or are looking for payment options.
