This instrument is used to analyze the entire retina, optic nerve and optic nerve fiber layer. With this technology we are able to examine in cross-section all of the layers of the retina and macula. Very often a number of ocular diseases can be diagnosed years before any other technology is able to. A few of these diseases include, glaucoma, macular degeneration, a number of optic nerve diseases and degenerations, ocular tumors, retinal detachments and many other retinal diseases. It was not until 2011 that this specific technology became available to eye doctors.
