Study of laser retinal coagulation using a closed-circuit television ophthalmoscope Wilton, Stephen Roland
Abstract
The mechanism and the history of retinal photocoagulation are reviewed. The eye and the light beam parameters are discussed as they affect the coagulation lesion, and optimum parameters are indicated. Some comparisons are made between photocoagulators of various types. A new reason which may account for the unpredictability of the lesion size for a given exposure, the variable focal length or lens-to-retina distance of the eye, is suggested and studied. The use of a television ophthalmoscope for studying retinal coagulation generally, and in carrying out special studies in this thesis, is reported. Some unique haemorrhages and blast effects obtained during coagulation experiments are reported.
