In vivo volumetric depth-resolved vasculature imaging of human limbus and sclera with 1 μm swept source phase-variance optical coherence angiography

摘要: We present nnnnnin vivo volumetric depth-resolved vasculature images of the anterior segment human eye acquired with phase-variance based motion contrast using a high-speed (100 kHz, 105 A-scans/s) swept source optical coherence tomography system (SSOCT). High phase stability SSOCT imaging was achieved by computationally efficient stabilization approach. The corneo-scleral junction and sclera were imaged angiography compared slit lamp from same eyes normal subjects. Different features rich vascular in conjunctiva episclera visualized described. This can be used as potential tool for ophthalmological research to determine changes outflow system, which may helpful identification abnormalities that lead glaucoma.
