Optical Coherence Tomography (OCT) is a non-invasive diagnostic instrument used for imaging the retina.
With an OCT, Dr. Randle is able to see a cross section or 3D image of the retina and detect the early onset of a variety of eye conditions and eye diseases such as macular degeneration, glaucoma and diabetic retinopathy
​(the top three diseases known to cause blindness).
