Abstract

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.

  Figure 1. Fundus photography and SD-OCT examination. At patient’s first visit, fundus photography shows yellowish retinal scar in the central fovea (A, B). SD-OCT shows bilateral symmetric disruption of the inner segment/ outer segment line disruption (C, D). SD-OCT = spectral domain optical coherence tomography.

  Figure 2. Fundus photography and SD-OCT examination. 3 years after the first visit, status of lesion cannot not be confirmed by fun-dus photography (A, B). SD-OCT examination shows bilateral symmetric disruption of the outer retina with no difference (C, D). SD-OCT = spectral domain optical coherence tomography.
