Title: (EN) Vascular entoptoscope
Abstract: front page image
(EN)

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. -GOVT 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). The United States government may have corresponding rights to the license and use of any resulting patent.
