Abstract
To describe a case of maculopathy induced by a handheld laser pointer in a 12-year-old male patient. He was exposed to handheld DPSS red laser pointer of 100 mW for some second. He was complained of central scotoma. His visual acuity decreased in both eyes. Fundus examination showed a grayish lesion in foveal region. Fluorescein angiogram showed hypofluorescence in the central macula in early phase with late ill-defined leakage. Optical coherence tomography (OCT) revealed the disruption of the retinal epithelium and edema in the foveal area. He was treated with one dose of Triamcinolone aceonide (40 mg) periocular injection in his both eyes combined with oral Chinese patent medicine for one month. Four weeks later, the patient’s visual acuity increased markedly, OCT showed unhealed retinal epithelium disruption. Laser pointer would be a dangerous “toys”, both parents and teachers should pay attention to it.
Highlights
Handheld laser pointers emit a bright signal even in daylight
In educational and business presentations, for instance, laser pointers are commonly used as eye-catching pointing devices; green laser pointers can be used in amateur astronomy to point the location of stars
The type of laser pointer we examined in the current case is called a diode-pumped solid-state (DPSS) laser pointer
Summary
Handheld laser pointers emit a bright signal even in daylight. Recent advancements have facilitated the development of low-cost, high-power laser pointers. Since 2010, many incidents on the careless use of high-power green laser pointers have been reported all over the world; notable are eye injuries, whose victims are commonly children [1,2,3,4]. Diodepumped solid-state (DPSS) laser pointers are characterized by their high stability, high efficiency, and low cost. This type of laser pointer can emit infrared light aside from visible laser. DPSS red handheld laser pointer in a Chinese child is presented in this article for discussion
