The increasing use of high-energy laser instrumentation for scientific
and therapeutic purposes has resulted in the proliferation of inadvertent
retinal injuries. The expanding use of Nd:YAG technology poses new threats
from accidental exposure. Reaction of retinal tissues from Nd:YAG laser insult
differs from the typical thermal injuries caused by argon and krypton lasers.
We report a case of laser injury to the macula in which we were able to closely
monitor the evolving retinal response to Nd:YAG disruption.
A 23-year-old researcher suffered sudden vision loss in his right eye
while focusing a reflected beam from a frequency-doubled Nd:YAG laser. He
was not wearing protective eyewear. His best-corrected visual acuity was 20/200
OD and 20/15 OS. He noted a large gray floater, with metamorphopsia and central
scotoma identified by Amsler grid. Fundus evaluation revealed vitreous hemorrhage
obstructing adequate macular visualization. Examination results from the left
eye were unremarkable.
