Optical Coherence Tomography
November 25, 2022
Optical coherence tomography (OCT) is a test that optometrists and ophthalmologists use to image the back of your eye. This includes the macula, optic nerve, retina, and choroid.
OCT can identify regions of the retina that are thinning, which indicates geographic atrophy. An OCT test is able to show changes in the retina in greater detail than any other instrument.
