Abstract: An ophthalmoscope of the indirect monocular type including an illumination system contained within the handle of the instrument, a viewing system contained within the viewing section of the instrument and a beam splitter contained within the bridge of the instrument, the bridge interconnecting the handle and the viewing section. The beam splitter reflects illumination to the patient''s retina and transmits the rays from the illuminated retina to the practitioner. The viewing system has a magnification less than unity with an adjustable focus to correct for refractive errors of the eyes of both patient and practitioner. The viewing system erects the inverted, reversed image of the patient''s retina. The several controls on the instrument determining the field of illumination, the illumination wave length and adjusting focus are grouped for convenient one-handed manipulation by the practitioner.
