ABSTRACT:
The gonioscope of the invention comprises a hollow tapered body with mirror surfaces formed on the inner side of the gonioscope or on the inserts placed into the recesses on the inner surface of the gonioscope. Several reflecting surfaces arranged at the same or different angles can be used. The device can be made disposable and molded with reflecting surface coatings applied onto the inner flats. According to one of the embodiments, the gonioscope can be used in combination with a meniscus lens that can applied onto the eye cornea and used as a support for sliding the front end of the gonioscope over the lens surface for orientation thereof at different angles to the optical axis of the eye.
