Optical Coherence Tomography
At Ensight Eyecare, our expert doctor and eye care team use the latest technology to accurately diagnose eye diseases and eye conditions. The OCT, or optical coherence tomography, is a critical device for the early diagnosis of several serious eye diseases and conditions.
Optical Coherence Tomography
OCT is a non-invasive scan of your retina that provides your doctor with detailed, 3D, color-coded, and cross-sectional images of the macula and the retina. These images enable your doctor to detect signs of eye disease in the early stages, which may not have any symptoms.
The OCT scan uses a laser which enables your doctor to obtain high-resolution images of your retina, macula, and optic nerve. You’ll sit in front of the OCT machine while the machine scans your eyes. 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?
If your doctor recommends an OCT scan, the scan can be used to diagnose, manage, or treat many different 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’re at risk of developing eye diseases or have other factors in your health history, Dr. Barton may recommend an OCT scan as part of your comprehensive eye exam. If you have already been diagnosed with an eye disease, an OCT scan will provide your doctor with valuable information to monitor your treatment.
