Temporary Visual Loss Due to Posterior Reversible Encephalopathy Syndrome in the Case of an End-Stage Renal Disease Patient

Posterior reversible encephalopathy syndrome is a clinical phenomenon associated with headache, altered mental status, seizures, and visual disturbances along with radiographic acute cerebral oedema. Several conditions are correlated with posterior reversible encephalopathy syndrome, with acute hypertension, eclampsia, and cytotoxic agents being the most common. This report presents a case of posterior reversible encephalopathy syndrome in a 45-year-old male with multiple underlying conditions, including hypertension, diabetes, and end-stage renal disease. Sudden onset of bilateral visual loss with mild systemic feature of dizziness was noted on presentation. Radiologic findings showed characteristic findings of posterior reversible encephalopathy syndrome. Following prompt control of hypertension and haemodialysis, resolution of symptoms was noted.
