Optical coherence tomography is a non-invasive imaging process that uses light waves to take cross-sectional images of the retina. These two- and three-dimensional images provide detailed information, such as the thickness of the retina, and allows your physician to compare progress photos for various treatment options. OCTs are commonly used to guide treatment for diseases such as glaucoma, age-related macular degeneration, central serous retinopathy, and diabetic retinopathy. It can also be used to identify disorders of the optic nerve.
This is a pain-free procedure. You are placed in front of the OCT machine and the chin is placed on a rest for stability. The device then scans the retina without making any physical contact with the eye. Many times, a simple eye drop will be applied to dilate the pupil for best imaging results. The whole process takes only about 10 minutes.
