Abstract
(EN)

Described herein are an apparatus and range of techniques used to study the retinal vasculature near the fovea, a description of the need and rationale for noninvasive in vivo monitoring of the retinal vasculature, a presentation of theoretical and practical considerations which demonstrate that entoptic visualization of the smallest capillaries near the fovea is optimized by a small short wavelength source (1 mm or less) rotating at 3.5 Hz in a circular path (radius 2 mm) imaged in the plane of the eye's entrance pupil and a discussion of the feasibility of using these techniques as a rese PAR Research relating to the development of the present invention was supported in part by grants from the United States Department of Health and Human Services (NIH EY08005 and EY07638).
