Abstract
An adapter for a lens retaining ring and associated indirect ophthalmoscopy lens used by an examiner or practitioner during examination of a patient's eye fundus with a biomicroscope. The adapter includes a body portion for spacing the lens mounted in the retaining ring a predetermined distance from the eye of the patient when the adapter-retaining ring-lens combination is positioned against the eye of the patient under examination. The adapter is adapted to engage the eyelids of the eye under examination, and is so constructed so as to aid in maintaining such eyelids open, and openings are provided in the body of the adapter to aid in preventing fogging of the lens mounted in the lens retaining ring. The adapter may be selectively removable from the associated lens retaining ring (which may be a conventional or known lens retaining ring) or may be integrally formed with the retaining ring.
