Clinical investigation of an infrared digital scanning laser ophthalmoscope.

Clinical investigation of a true color scanning laser ophthalmoscope.

OBJECTIVE To show true color scanning laser ophthalmoscope (SLO) images produced by simultaneously imaging the retina with red, green, and blue lasers. METHODS Low-power red, green, and blue lasers were combined using fiber optics. By rapidly pulsing the lasers, each point on the fundus is illuminated by the 3 colors in quick succession, with the total power level being similar to that from a...

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...

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...

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...
