Attention is drawn to the possibility of performing monocular indirect ophthalmoscopy with a pen torch and a condensing lens when facilities for binocular indirect ophthalmoscopy are not available.

Improved illumination in indirect ophthalmoscopy.

THE indirect method of ophthalmoscopy offers several advantages over the direct method; these include larger field of view, better penetration of hazy media, greater depth of focus, and closer approach to the ora serrata (Schepens and Bahn, 1950).
