A rare case of snake bite-induced leukoencephalopathy with cortical blindness

Snake envenomation causes considerable morbidity and mortality, manifesting as local tissue damage, hematological disturbances, renal impairment, and neurological complications. Snakebite is a significant public health concern in tropical regions, including India, where a diverse population of snakes thrives. Neurological manifestations following venomous snake bites are predominantly due to the neurotoxic or coagulopathic effects of the venom. Although neurological complications are primarily linked to viper bites, cases of neurotoxic snake bite-induced leukoencephalopathy are rare in the literature. We report a rare case of cortical blindness following snake bite-induced leukoencephalopathy. Early intravenous administration of polyvalent anti-snake venom remains the cornerstone of treatment. A timely diagnosis supported by imaging techniques like magnetic resonance imaging (MRI), and a high index of suspicion is crucial for effective management and better systemic and visual prognosis.
