Abstract
Described herein are a range of techniques and apparatuses 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 short wavelength source of light which is constrained to enter the eye through a small limiting aperture moving in space near the eye at an optimized velocity in a circular or irregular path, and a discussion of the feasibility of using these techniques in a museum or novelty device as well as a research and clinical tool.
