Laser Pointer Maculopathy (SD-OCT)

Retina -> Light Toxicity
Patient: 7 years of age, male, BCVA 0.8 at OD, 1.0 at OS, IOP 14/15 mmHg. General Medical History: empty. Ocular Medical History: injury of OD by a red handheld diode laser pointer 4 days before. Main Complaint: decreased central vision. Purpose: to demonstrate retinal injury by a laser pointer. Methods: SD-OCT Heidelberg Engineering. Findings: SD-OCT: defect in the outer segment and inner high reflective layer. The external limiting membrane is hyperreflective anterior to the foveal defect, interruption of the external limiting membrane and the inner and outer segment junctions. Discussion: Solar retinopathy by a laser pointer is gene rally characterized by involvement of the outer retinal layers with defects at the level of the inner and outer segment junction of the photoreceptors as well as in the inner high reflective layer (1, 2). Optical coherence tomography might delineate the retinal injury site in vivo demonstrating a characteristic excavation in the outer hyperreflective layer corresponding to the retinal complex.
