Laser ophthalmoscope and coherent light.

Laser ophthalmoscope and coherent light.

SINCE the advent of laser sources producing coherent light, that is plane polarized and emitted as an almost parallel beam, there has been much conjecture about its use in ophthalmological practice. The human eye, with its clear media capable of refracting a parallel beam to image on the retina, appeared to be the logical target for such a unique source. The tissue reaction consequent to the re...

Directional light scanning laser ophthalmoscope.

The cone photoreceptor mosaic of the living human eye has in a limited number of cases been imaged without the use of wavefront-correction techniques. To accomplish this, the directionality of the photoreceptors, as manifested by their waveguiding properties, may be used to advantage. In the present paper we provide a model of our recently proposed directional light scanning laser ophthalmoscop...

Tracking scanning laser ophthalmoscope (TSLO)

The effectiveness of image stabilization with a retinal tracker in a multi-function, compact scanning laser ophthalmoscope (TSLO) was demonstrated in initial human subject tests. The retinal tracking system uses a confocal reflectometer with a closed loop optical servo system to lock onto features in the fundus. The system is modular to allow configuration for many research and clinical applica...

Compact Adaptive Optics Line Scanning Laser Ophthalmoscope

We have developed a compact retinal imager that integrates adaptive optics (AO) into a line scanning laser ophthalmoscope (LSLO). The bench-top AO-LSLO instrument significantly reduces the size, complexity, and cost of research AOSLOs, for the purpose of moving adaptive optics imaging more rapidly into routine clinical use. The AOLSLO produces high resolution retinal images with only one moving...
