A case of retinal light damage by green laser pointer (Class 3b)
- 376 Downloads
In previously reported cases of retinal injury from red (He–Ne; 632 nm) laser pointers, the maximum output was 5 mW or lower (Class 3a), and gazing time was 10 s or longer [1, 2, 3]. Higher-energy, green (532 nm) laser pointers are increasingly displacing red lasers and, here also, injuries have been reported . We report a case of retinal light damage caused, after a moment’s gaze, by a high-output (Class 3b) green laser pointer unavailable to the general public in Japan that was brought from overseas.
