Abstract
Optical coherence tomography (OCT) is a well-established research tool for vision research in animal models capable of providing in vivo imaging of the retina. Structural OCT can be enhanced using OCT angiography (OCTA) processing in order to provide simultaneously acquired, automatically co-registered vascular information. Currently available OCT. Currently available OCTA lack either large field of view or high resolution. In this study we developed a wide-field (60-degree), high-resolution (10.5-µm optical transverse) and high-sensitivity (104-dB) OCTA-enabled system for non-human primate imaging and with it imaged multiple disease models, including models of age-related macular degeneration (AMD), Bardet-Biedl Syndrome (BBS), and the CLN7 variant of Batten disease. We demonstrate clear visualization of features including drusen, ellipsoid zone loss, vascular retinopathy, and retinal thinning in these eyes.
