Recovery From Pulsed-Dye Laser Retinal Injury

Arch Ophthalmol. 1992;110(12):1688-1689. doi:10.1001/archopht.1992.01080240026018

The increased use of lasers in industry, science, and medicine has led to a growing case report file dealing with accidental exposure of the eye to laser radiation.1-3 Laser-induced injury of the foveal region is of greatest concern since visual prognosis is expected to be very poor.

Report of a Case.  —A 29-year-old male research scientist sustained a foveal hemorrhage from exposure to one or two 0.55-MJ, 620-nm, 20-nanosecond laser pulses from orange laser light emitted by a neodymiumYAG pumped-dye laser. He was at arm's length from a beam-positioning mirror and looked directly at the mirror when the beam position was not apparent. He experienced a brilliant orange flash of light in his right eye and then saw only black. Visual acuity was counting fingers at 180 cm in the right eye, with an 8° central scotoma. A preretinal foveal hemorrhage with surrounding radiating folds was noted (Fig 1),
