title: [Manual opthalmoscope OR-2].
abstract: An ophthalmoscope of the OP-2 type has been designed and built to investigate the eye fundus in white and "red-free" light and also intended for use with an orange photofilter. The device enables the eye fundus to be examined without restoring to a medicamentous dilatation of the pupil. The illumination produced by the ophthalmoscope is nearly twice as great as the one provided for by the earlier manufactured ophthalmoscope, model sigma0-61. The slit and diaphanoscopic attachments that go with the ophthalmoscope allow it to see the "optical sections" of the cornea, the iris, as well as the crystalline lens and also to make demonstrable sections to the eye with lesser transparency, this enabling one to judge about the presence of tumours and other pathological conditions of the eyeball.
