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 reti-nal scar was observed at the foveal area. The spectral domain optical coherence tomography (SD-OCT) showed inner seg-ment/outer segment line disruption. The best corrected visual acuity was 4/20 in both eyes and SD-OCT showed a remaining in-ner segment/outer segment line disruption after 3 years.

Conclusions

Maculopathy can result from exposure to a high voltage arc discharge exposure.

Keywords: High voltage spark, Inner segment/outer segment line, Maculopathy, Spectral domain optical coherence tomog-raphy (SD-OCT)

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.
