Optical Coherence Tomography

Dr. Artee Nanji and her team utilize the latest technology to accurately diagnose eye diseases and other ocular conditions. The OCT, or optical coherence tomography, is a device used for the early diagnosis of several serious eye diseases and conditions, some of which have no obvious symptoms in the early stages.

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

The OCT laser scan enables your 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 that the scan of your eyes 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?    

If your doctor recommends you get 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 are at risk of developing an eye disease or have other factors in your health history, your Primary Eye Care doctor 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.
