A Case of Bilateral Maculopathy Caused by High-Voltage-Induced Spark Injury

PURPOSE: To report a case of maculopathy after exposure to a high-voltage spark. CASE SUMMARY: A 40-year-old male patient visited our clinic complaining of visual disturbance in both eyes 1 day after exposure to a high voltage arc discharge. His best corrected visual acuity was 4/20 in both eyes. On fundus examination, a yellowish retinal scar was observed at the foveal area. The spectral domain optical coherence tomography (SD-OCT) showed inner segment/outer segment line disruption. The best corrected visual acuity was 4/20 in both eyes and SD-OCT showed a remaining inner segment/outer segment line disruption after 3 years. CONCLUSIONS: Maculopathy can result from exposure to a high voltage arc discharge exposure.
