Can the Zeiss Cirrus HD-OCT Provide Early Diagnosis of AMD?

Can early stage Myopic Macular Degeneration (i.e., when the patient only notices minor changes in the Amsler Grid), be diagnosed on the Zeiss Cirrus HD-OCT?

According to this post on another eye doctor blog, Zeiss Cirrus OCT allows scanning of a patient’s retina for glaucoma and macular degeneration without dilation. Specifically, the Zeiss OCT uses ultrasound and a scanning laser to make a very high resolution, 3D image of the inside of a patient’s eye, much like that of an MRI, and allows the examining doctor to identify retinal objects as small as 4 microns (for comparison, a single sheet of 20 lb copy paper is 100 microns thick). Thus, Zeiss OCT allows detection of glaucoma and macular degeneration much earlier as well as detection and tracking of subtle retinal changes. See:

perhaps. maybe dr. wong knows better. but since there are no drusen in myopic degeneration, i suspect it would be very difficult. clinically, it’s irrelevant. we do not treat myopic degeneration unless there is leakage/bleeding which comes much later and is easily diagnosed.
