Summary

The objective of this study is to image retinal vascular alterations in patients with retinal disease using the AngioVue OCT-A system and understand the information these images provide. The investigators will image study participants who have retinal diseases with the AngioVue unit (Optovue) and will collect relevant clinical data to understand the nature of the information contained in images obtained on AngioVue. This study being conducted under an abbreviated IDE. The investigators will analyze data using descriptive statistics. Risks related to light exposure will be managed by ensuring that the exposure to the AngioVue light source is well below maximum permissible limits for safe exposure.

DEVICE

AngioVue SD-OCT

OCT-A allows noninvasive, high-resolution imaging of the microvasculature of the retina and choroid, without intravenous dye administration. SD-OCT units use the light source used in commercially available and FDA-cleared OCT units on a modified platform. Optovue, Inc. has developed a customized SD-OCT system that implements a novel algorithm, the amplitude-based method of split-spectrum amplitude-decorrelation angiography (SSADA) for OCT-A. This detects motion in the blood vessel lumen by measuring the variation in reflected OCT signal amplitude between consecutive cross-sectional scans. Optovue has integrated the novel SSADA algorithm into their commercially approved RTVue SD-OCT unit for their OCT-A unit, the AngioVue. This unit is being conducted under an abbreviated IDE.
