Laser devices are ubiquitous in modern medicine, industry, military, and everyday life. Lecturers often use hand held laser pointers at conferences. Eye injuries due to laser exposure are a concern because optical radiation from 400 nm to 1400 nm penetrates into various ocular structures. The eye is the only organ vulnerable to this range of wavelength. The blink reflex and aversion response restrict the duration of laser exposure to 0.15-0.25 seconds. These natural protective mechanisms are effective against low power laser pointers. However, retinal injury can occur following prolonged (>10 seconds) exposure to low-power laser pointers as well. High-power handheld laser pointers (up to 1200 mW) are now also publicly available via the internet. These laser pointers can be used to light fireworks from a distance, light cigarettes and burn through plastic bags, this study will show our experience with the patients presented with retina injury caused by momentary exposure to a highpower blue laser pointer. 27 patients with a history of laser pointers were presented with the following: full thickness macular hole (FTMH) in 17 eyes, intraocular hemorrhage in 7 eyes, an outer retinal disruption in one eye, an epiretinal membrane in one eye, and a schisis-like cavity in one eye. Initial best-corrected visual acuity (BCVA) had a mean of 20/290 (range: 20/40 to 4/200). Neodymium: yttrium-aluminum-garnet Nd:YAG hyaloidotomy was performed in five eyes with sub hyaloid hemorrhage and pars plana vitrectomy (PPV) with or without tamponade in 15 eyes. While, observation was elected in 7 eyes, visual acuity improved almost in all patients spontaneously or following intervention. High-power handheld laser pointers are extremely dangerous to the eye and public awareness should be encouraged. Recent Publications 1.
