title: Retinal Injury Secondary to Laser Pointers in Pediatric Patients.
abstract: This case report describes 4 male children (age, 9-16) who had laser-related retinal injury to the macula of 1 eye or both eyes due to the mishandling of the laser pointer devices at a single vitreoretinal clinical practice. The presenting symptoms associated with laser pointer injury include central vision loss, central scotoma, and metamorphopsia. Clinical findings of laser-related retinal injury include reduced visual acuity, disruption of the photoreceptor ellipsoid zone, retinal pigment epithelium atrophy, and choroidal neovascular membrane formation. Disruption of the foveal ellipsoid zone (photoreceptor inner segment/outer segment layer) is the most common finding on optical coherence tomography imaging. Three patients had potential irreversible vision loss. Laser pointers are readily available and appropriate use of laser pointers in the pediatric population must be emphasized due to the potential irreversible retinal injury. Health professionals, school teachers, and parents should raise public awareness of this emerging public health issue by educating children about the dangers of laser pointers. Laser pointer devices among children should be discouraged and limited due to the possibility of permanent harm to themselves and others. Legislation and laws may be required to better control the sale and use of these devices.
