Retinal Injury Following Laser Pointer Exposure.
BACKGROUND Recent years have seen a marked increase in laser-pointerrelated injuries, which sometimes involve severe retinal damage and irreversible visual impairment. These injuries are often caused by untested or incorrectly classified devices that are freely available over the Internet. METHODS We reviewed pertinent publications retrieved by a systematic search in the PubMed and Web of Sci...
متن کاملPediatric Bilateral Blue Laser Pointer-Induced Maculopathy
BACKGROUND We report the first case of pediatric bilateral blue laser pointer maculopathy with complete resolution of visual symptoms. CASE A 12-year-old boy presented with bilateral decreased visual acuity and central scotomata after blue laser pointer exposure. He was treated with a Medrol Dosepak and topical nonsteroidal anti-inflammatory drug (NSAID), with gradual visual acuity improved f...
متن کاملBilateral macular injury from a green laser pointer
We report the case of a 13-year-old boy who had a bilateral macular injury after playing with a green laser pointer for a duration of 1 minute. Clinical examination revealed a decrease in visual acuity and macular injury in both eyes, and imaging investigations revealed a bilateral macular lesion due to exposure to the laser pointer. At 3 months' follow up, visual function had improved but rema...
متن کاملA quantum laser pointer.
The measurement sensitivity of the pointing direction of a laser beam is ultimately limited by the quantum nature of light. To reduce this limit, we have experimentally produced a quantum laser pointer, a beam of light whose direction is measured with a precision greater than that possible for a usual laser beam. The laser pointer is generated by combining three different beams in three orthogo...
متن کاملA Green Laser Pointer Hazard
An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be noticed by most users of such pointers. We find that this infrared emission derives from the design of the pointer, and describe a simple method of testing for infrared emissions using common household items.
