Optical Coherence Tomography
Optical coherence tomography (OCT) is a non-invasive scan of the retina that will provide our eye doctors with detailed, 3D, color-coded, and cross-sectional images of the macula and the retina. These images allow us to detect signs of eye disease in the early stages, which may not have any symptoms.
The OCT scan uses a laser that enables your eye doctor to obtain high-resolution images of your retina, macula, and optic nerve. You will be asked to sit in front of the OCT machine so that the eye scan can be completed. Nothing touches your eye, and the test is painless. The test takes about 5–10 minutes to complete.
How are Optical Coherence Tomography (OCT) Scans Used?
During your comprehensive eye exam, an OCT scan can be used to diagnose, manage, or treat several eye diseases and conditions, including the following:
- Diabetic retinopathy
- Age-related macular degeneration
- Macular edema
- Glaucoma
- Drusen
- Retinal detachment, occlusions, or bleeding
- Macular hole
- Neovascularization
If you have a family history or other risk factors for developing eye diseases, our eye doctor may recommend including an OCT scan with your comprehensive eye exam. If you have already been diagnosed with an eye disease, the OCT scan will provide our optometrist with the information needed to monitor your treatment.
