Measure	SD-OCT Angiography Study participants will undergo imaging of both eyes with the AngioVue unit (approx. 60 seconds/eye), per standard operating protocol. Imaging is noncontact, and pharmacologic dilation will not be used for the purposes of this study. In most instances, study participants will undergo only a single imaging session on a single day. However, potential participants will be asked to consent for additional imaging sessions (up to 12) that may occur over the course of subsequent future visits to the clinic. Additionally, study participants will be asked to consent to prospective collection of clinical and demographic data, to correlate findings of OCT-A imaging to subsequent clinical course. 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.
