In a preferred embodiment, a portable ophthalmoscope having low-power telescope elements and having an internal source of viewed-field illumination, relies on a patient\s focusing properties to inspect the fundus of the eye. A laser-beam source is flexibly coupled to the patient end of the ophthalmoscope viewing axis and, after optical expansion and collimation, is folded into coincidence with the ophthalmoscope axis. A dichroic (filter) is the mirror via which the folding takes place, the filter being selected for a very narrowly limited spectral band o...
A portable indirect photocoagulation delivery system, comprising in combination, a hand-held ophthalmoscope including a low-power afocal telescope comprising a housing and optical elements that can be focused in the interior of an inspected eye, a light source carried by said housing and means including a beam splitter on the telescope axis for projecting light over an illuminated central field region in the interior of the inspected eye; laser means having a radiation-beam output, means including an elongate flexible optical-fiber cable coupled at one e...
