Multimodal imaging in handheld laser-induced maculopathy

Abstract

Purpose: To describe the clinical and imaging findings in 3 patients with maculopathy secondary to handheld laser exposure.

Design: Retrospective, observational case series.

Methods: We evaluated the multimodal imaging including fundus autofluorescence and spectral-domain optical coherence tomography (OCT) for 3 patients with histories of exposure to handheld lasers.

Results: An 18-year-old woman with a history of repetitive self-inflicted handheld laser exposure was found to have bilateral outer retinal streaks in the macula and the superior peripheral retina on both ophthalmoscopy and multimodal imaging. Initial spectral-domain OCT revealed vertical hyper-reflective bands at the level of the outer retina corresponding to the streaks. An 11-year-old boy who played with a green laser developed a yellow foveal lesion and outer retinal streaks in the superior macula. Spectral-domain OCT showed vertical hyper-reflective bands in the outer retina corresponding to the streaks. A 14-year-old boy developed bilateral focal foveal lesions and ellipsoid loss on spectral-domain OCT following peer-inflicted laser injury.

Conclusions: In a series of 3 patients, outer retinal streaks were associated with self-inflicted handheld laser injury. In contrast, accidental and peer-inflicted laser injuries were found to result in focal foveal lesions.
