Abstract
The instrument described in this paper combines a black and white television camera with a binocular indirect ophthalmoscope. Simply constructed and easily operated, the instrument is a prototype that demonstrates the practicality and potential of indirect television ophthalmoscopy. It presents the large field, motion, and depth of focus of indirect ophthalmoscopy on a screen for audience viewing during an actual examination. The flexibility of the instrument makes it possible to demonstrate relationships within the fundus by slow panning to explore the fundus periphery with scleral depression.
