Bilateral Electric Shock Induced Cataract

Abstract

Electric shock injury may cause various ocular complications. The severity of the complications depends on the voltage and site of passage of electric shock. The probability of ocular involvement rises more if the injury occurs at the scalp or face. Electric shock induced cataract is usually bilateral. The exact pathogenesis of cataract development is unknown. Direct coagulation of lens proteins and the osmotic changes following damage to the subcapsular epithelium are thought to be responsible. Other ocular complications like conjunctival hyperemia, interstitial corneal opacities, uveitis, miosis, spasm of accommodation etc may occur. Some rare complications like optic nerve coagulation, necrosis of retina, choroid and optic atrophy have been reported. Macular oedema may lead to the development of macular cysts or holes. Paresis of extraocular muscles have been frequently observed.
