Visual screening via television.

Using a test developed in 1977, visual screening via television is now beginning to be carried out on a large scale. The test consists of two parts, a visual acuity test and a visual field test using a modification of the multiple pattern method of Harrington and Flocks. It has been useful and has been well received by the public.

Retinal injury due to industrial laser burns.

Ocular industrial lasers burns in seven patients were analyzed as to cause, severity, and type of injury. Ocular damage ranged from minimal retinal burns to extensive areas of damage with commotio retinae and vitreous hemorrhage. Visual loss ranged from complete recovery without residual defect to a profound decrease in central acuity.

Mass visual screening via television.

Videotaped programs that could be used for screening of visual acuity and of visual fields by means of broadcast television have been developed and tested. The tests are designed to be effective regardless of the size of the viewer's television screen. Inevitably, false-positive and false-negative results would occur, which would have to be carefully explained at the time the tests were broadcast.
