Hello there
Are you interested in finding out what is this test because your doctor has recommended you to do it or you are just curious?
The OCT or Optical coherence tomography test is capable of creating digital images through the use of special beams of light. Goal of this test is to create a contour map of the optic nerve and measure the retinal nerve fiber thickness. This test is very similar to the CT scan so if you have ever done it you are familiar with the procedure.
Detecting the slightest loss of optic nerve fibers in order to diagnose glaucoma is the main reason why would your doctor recommend you to do this test. Detecting glaucoma at the early stage is essential to stop the progression of this disease and it can help in preserving your vision.
