Electric shock induced Purtscher-like retinopathy

Paracentral Acute Middle Maculopathy and Central Retinal Venous Occlusion following Electrical Injury

Purpose

To report a case of central retinal vein occlusion (CRVO) and paracentral acute middle maculopathy (PAMM) following electric shock injury. Case Description. A 45-year-old male presented with a significant painless decreased vision in the right eye following an electrical injury of the right hand in his workplace. The best-corrected visual acuity (BCVA) of the right eye was 20/40. Funduscopic examination of the right eye revealed diffuse superficial and deep intraretinal hemorrhages, mild venous tortuosity, and an area of the pale retina. Optical coherence tomography (OCT) demonstrated hyperreflective band-like lesions in the middle retinal layers. Patchy areas of vascular flow void in deep capillary plexus seen in OCT angiography of the right eye were compatible with PAMM. Fluorescein angiography of the right eye was indicative of delayed venous filling suggestive of CRVO. The left eye was completely normal on exam and imaging.

Conclusion

This report illustrates the occurrence of CRVO associated with PAMM following electric shock injury. Electrical injury leads to a wide range of retinal manifestations. Clinicians need to pay attention to any hyperreflectivity and thinning of middle retinal layers in OCT in cases with the presentation of sudden visual loss following electrical injuries.

Electric Shock Retinopathy: Case Report of a Late Retinal Manifestation

Purpose:

This is a case report of a male patient who suffered a high-voltage electrical burn and presented with bilateral pigmentary retinopathy.

Methods:

A 40-year-old man presented with bilateral vision loss following a high-voltage electrical injury sustained 10 years earlier. Family history, ocular history, and anterior segment evaluation were unremarkable.

Results:

Fundus examination revealed bilateral optic disc pallor, widespread areas of chorioretinal atrophy, and pigmentary changes surrounding the optic disc that partially involved the macula with some spared areas located on the superior retina.

Conclusions:

Retinal manifestations following a high-voltage electrical injury can resemble other hereditary and inflammatory diseases with similar clinical patterns, therefore, a meticulous family, medical, and clinical evaluation is essential.
