The argon laser energy necessary to create a threshold visible retinal coagulation in rabbits and monkeys after a one-hour observation period has been calculated utilizing a 50% P histogram. Energies required during 2, 4, 10, and 20 second exposure intervals or image diameters of 105μ (monkeys) and 115μ (rabbits) were determined and the implications discussed.
