Synopsis:

Although fundus observation with ophthalmoscopy BIO remain the standard of care, myriad imaging devices continue to reveal that many disorders are invisible to BIO in early stages.

OCT allows us to assess each retinal layer including, for example, the photoreceptors, which are never visible with BIO.

Advances in OCT allow views of 12x9 mm of fundus as well as revealing the choroid as never before.

Multi-spectral imaging MSI using 10 or more LEDs allow detection of RPE and choroidal lesions often invisible to even OCT.

Ultra-widefield UWF devices allows over 80 of the fundus to be viewed in 1 image. Auto-fluorescence AF permits imaging thqt goes beyond structure and reveals function RPE involvement is often invisible to all other devices, save for AF.

UWF fluorescein angiography permits vascular leakage to be documented beyond the equator.

Although not FDA approved, devices that document B-amyloid plaques the bio-marker for Alzheimers disease- AD in the retina will soon be available.
