Purpose:
To illustrate the clinical findings in a patient who experienced an electrical shock injury.
Methods:
Observational case report. A 54-year-old man who experienced an electrical shock injury was followed up with fundus photography, fluorescein angiography, and indocyanine green angiography. Visual acuity, electroretinography, and visual field were also performed. The visual acuity of the right eye was 20/25 and the left eye was 20/20. Bilateral meridional atrophy areas were found around the optic nerve in fundus color images. Axial symmetrical meridional atrophies around the optic disk in both eyes were found in the patient's fundus fluorescein angiography and indocyanine green angiography images.
Results:
Atrophy of bilateral retina and choroid can be found on fundus autofluorescence, fundus fluorescein angiography, and indocyanine green angiography in this electrical current-injured case, which looks like meridional direction from superior temporal to inferior nasal through optic disk.
Conclusion:
We report a rare case of bilateral peripapillary meridional retina-choroidal atrophy after electrical injury. Because of the variable timing and spectrum of ocular findings, patients experiencing electrical injury without profound vision loss should undergo long observation.
