Characterization Of The Macular Choriocapillaris In Dry Age-Related Macular Degeneration Using Swept-Source Optical Coherence Tomography Angiography (Thesis)

The purpose of this study was to characterize further, using swept-source (SS-) optical coherence tomography angiography (OCTA), the relationship between dry age-related macular degeneration (AMD) and the macular choriocapillaris (CC), which may have pathophysiologic and therapeutic implications. It included (1) a topographic analysis to determine if there is a significant relationship between dry AMD stage and macular CC perfusion, and (2) an investigation of the predictive value of macular CC perfusion with respect to geographic atrophy (GA) growth rate. Study design was retrospective and cross-sectional. A database of 6x6 mm fovea-centered swept-source OCTA images of the CC from eyes with ...
