[Manual opthalmoscope OR-2].

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.

[Polarization method of examining the fundus and anterior chamber of the eye].

The method using polarization light proved to be efficient for examining eye tissues. It provides better contrast of some ocular elements, and thus, more reliable detection of pathological changes, more complete extinction (relaxation) of reflexes which hamper the observation and photograph of different eye parts. To interprete the patterns observed on the fundus in crossed polaroids, a matrix method is recommended for calculation of intensity of light passing through the optically-anisotropic layers of the eye ball. Data of clinical examinations carried out on pilot models of ophthalmological instruments confirmed diagnostic value of the polarization method for the eye study.
