Abstract:
Diagnostic classification techniques used to diagnose cataracts, the world's leading cause of blindness, are currently based on subjective methods. Here, we present optical coherence tomography as a noninvasive tool for volumetric visualization of lesions formed in the crystalline lens. A custom-made swept-source optical coherence tomography (SS-OCT) system was utilized to investigate the murine crystalline lens. In addition to imaging cataractous lesions in aged wildtype mice, we studied the structure and shape of cataracts in a mouse model of Alzheimer's disease. Hyperscattering opacifications in the crystalline lens were observed in both groups. Post mortem histological analysis were performed to correlate findings in the anterior and posterior part of the lens to 3D OCT in vivo imaging. Our results showcase the capability of OCT to rapidly visualize cataractous lesions in the murine lens and suggest that OCT might be a valuable tool that provides additional insight for preclinical studies of cataract formation.© 2020 Optical Society of America under the terms of the OSA Open Access Publishing Agreement.
