Case 11-2. Laser Injury

Clinical Summary

A 28-year-old graduate student accidently gazed into a pulsed titanium:sapphire laser with his left eye while in the laboratory. The laser was operating at 840 nm, with 500 |ij pulses stretched to 1 ps at a 1 kHz repetition rate. The exposure to the eye was less than 1 second off of a 10% reflector. Dilated fundus examination (A) two days later revealed a spindle-shaped, hypopigmented lesion bisecting the fovea. No clear abnormal it v was visualized on fluorescein angiography (not shown). The visual acuitv was 20/25,

Optical Coherence Tomography

An OCT tomogram (B) acquired coincident with the burn showed a mild disturbance in the retinal pigment epithelium and some enhanced reflectivity in the photoreceptor layer, but otherwise no morphological damage.
