An active duty marine corps service member had bilateral full thickness macular holes induced following accidental Q-switched laser exposure from a hand held Neodymium range finder (ANGVS-5). The right eye had a large hole nasal to the fovea, while the left eye had a much smaller hole closer to the fovea centralis. Over the 18 months following the ...

A 31-year-old man sustained a 1,064-nm Q-switched Nd:YAG laser injury to his left eye. One month after the injury, the fundus and optical coherence tomography (OCT) examination demonstrated a full-thickness macular hole of approximately 820 ?m in diameter. After vitrectomy and internal limiting membrane peeling, OCT showed closure of ...

Here, we report the case of a patient who sustained Nd: YAG laser macular injury with subsequent 6 year follow-up evaluation. A 23-year-old female was accidentally exposed to a Q-switched Nd: YAG laser without protective goggles. Upon initial evaluation, the best-corrected visual acuity of her affected eye was 20/100 OD. Fundoscopic ...
Ocular injuries resulting from exposure to laser beams are relatively uncommon since there is normally a low probability of a relatively small-diameter laser beam entering the pupil of an eye. This has been the accident experience to date with lasers used in the research laboratory and in industry. A review of the accident data suggests that at least one type of laser is ...
A 21-year-old man received an accidental laser injury to three separate foci of the retina of his right eye from a Q-switched Nd:YAG laser target designator emitting at 1064 nm, operating at 10 Hz, with a pulse duration of 20 ns. The nominal output of this device was 50 mJ, and the diameter of the output beam was approximately 4 cm. The extent of ...

Legal entanglements prevent publication of details on most laboratory and industrial laser accidents in the USA. Many macular injuries involving the fovea show no signs of recovery after several years. Both single eye (usually the dominant one) and binocular exposures are found usually resulting in large deficits in visual performance. The primary lesion ...

The effects of human laser eye damage may be modeled by stabilizing a small portion of the visual field on the retina. We compared the effects of such artificial scotomas with accidental human laser induced retinal damage on contrast and recognition sensitivity. Horizontal and vertical output voltages from a purkinje eye-tracker controlled video generated scotomas. Contrast ...
