  • OCT Testing

  • An OCT scan (optical coherence tomography) tests the thickness of the tissues inside the eye, which helps the doctor diagnose diseases like diabetic retinopathy and macular degeneration, as well as monitor the progression of glaucoma.

    The patient focuses on a fixation target centered over one eye at a time and does not blink for five seconds while the instrument scans. The results are available for the doctor to review within seconds. Coupled with visual field testing, the doctor receives a fuller picture of the progression of glaucoma or macular degeneration.
