ABSTRACT:
A modified scanning laser ophthalmoscope expands the range of clinical applications of the conventional scanning laser ophthalmoscope, being able of presenting the scanning laser raster with graphics to the retina and simultaneously allowing the observation of the anterior segment on the display monitor. The device, including a beamsplitter, infrared lightsource, scanning laser ophthalmoscope, CCD camera, and optical filters, determines unambiguously in real-time the entrance pupil of the Maxwellian view scanning laser ophthalmoscope. The location of the entrance pupil and stimulus position on the retina can be moved independently.
