Ying WU, Ping-Bo Ouyang and Luosheng Tang

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.
