Abstract:
The most common ocular manifestation following electric shock injury is the development of cataract. Retinal manifestations can vary from development of macular holes to retinal detachments. Purtscher-like retinopathy following electrical injury has not been reported till date. We hereby present a case of a 19-year-old electrician who presented with grossly reduced vision in the right eye of 2 months following an electric shock. The fundus of the right eye showed macular ischemic degeneration, occluded vessels, cotton-wool spots, and hemorrhages. Optical coherence tomography angiography revealed presence of capillary drop-out in the para-foveal region, which was more pronounced in the deep capillary plexus. Electric shock injury can lead to a clinical picture simulating Purtscher's retinopathy. The electrical injury leads to a more extensive damage to the deep capillary plexus as compared with the superficial plexus.
