ABSTRACT:
A binocular scanning laser ophthalmoscope expands the range of clinical applications of the conventional scanning laser ophthalmoscope, being able of presenting the scanning laser raster with or without graphics to one eye or to both at the same time and simultaneously allowing the observation of either eye or both on the display monitor. The device, including a beamsplitter, mirrors, and optical filters, enables switching up to video between the different options without the need for moving the scanning laser ophthalmoscope from one eye to the other. Lenses can be inserted in the optical pathway for the correction of ametropia. A pupillary distance control for both eyes optimizes the Maxwellian view on both sides.
