TV indirect ophthalmoscope.
A prototype of TV indirect ophthalmoscope (black-and-white type) was developed to enhance education in ophthalmology. Its weight is 450 g, and pictures obtained were fairly satisfactory. The authors have used this ophthalmoscope not only for practicing indirect iphthalmoscopy by students, but also as monitoring device during retinal surgery.
