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. The kinds of lasers causing these injuries were neodymium YAG, argon, krypton, and rhodamine dye. Severity of injury was related to several factors. Some degree of carelessness was involved in all injuries.

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.

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. A great advantage of the testing method is that many thousands of people can be simultaneously screened in a 10-minute period. The accuracy of the test is discussed. The videotape program is now available for broadcast from the National Society to Prevent Blindness, Inc.
