An instructional video on the uses of the binocular indirect ophthalmoscope

1 May 1993


This video presents an orientation to the binocular indirect ophthalmoscope (BIO). Included are explanations of the equipment, its optical principles, fitting and adjustment of the equipment, a comparison and contrast of the different condensing lenses available, and how to get a view and examine the retina. A BIO headset with a video camera installed was used to collect views of the retina as seen through a condensing lens, and these views are used to familiarize beginners with the appearance of retinal landmarks. After the conclusion of the video, other interesting views not used in the video are included. The video is designed to be used in a laboratory setting, with qualified teaching personnel present to help students appreciate what is seen. A short handout accompanies the video, and includes reproductions of the tables used and comments on the retinal views seen.
