UMD: Ophthalmoscopes that use a low-power laser beam for scanning horizontally and vertically across the retina, producing an electronic image with depth resolution, which is particularly valuable in creating three-dimensional (topographic) images of the optic disc. Retinal conditions such as edemas, scars, and macular holes are assessed using this technique.,SPN: An ophthalmoscope is an AC-powered or battery-powered device containing illumination and viewing optics intended to examine the media (cornea, aqueous, lens, and vitreous) and the retina of the eye.
