Abstract: An indirect ophthalmoscope is used in the observation of the eye, and comprises viewing optics through which, in use, at least part of said eye is viewed. Light from the eye travels to and through the viewing optics along a viewing path, and the ophthalmoscope includes a lens (36) which is movable between an operative position (in which it is situated in the viewing path) and an inoperative position (in which it is situated clear of the viewing path). The lens 36 can be used to enable the observer to see a magnified image of the eye under examination.

Abstract: A portable, binocular direct ophthalmoscope. A frame carrying a binocular optical system is suspended for rotation about a pivot axis from one end of a support beam; an opposite end of the support beam is attached to a handle. A beam splitter block mounted to the frame carries an illumination source for light emission along an illumination axis and into an eye of a subject. Left and right beam splitting mirrors attached to the block are symmetrically and obliquely disposed on opposite sides of the illumination axis. Light reflected back from the subject's eye is split by the beam splitting mirrors into a left-directed beam and a right-directed beam, which are each reflected rearward by laterally spaced apart deflection mirrors through left and right dioptric disk assemblies and thence into the left and right eyes of an observer, respectively.
