Posterior reversible encephalopathy syndrome (PRES) is a condition of neurotoxicity that presents with a sudden onset of symptoms including headache, altered mental status, seizures, and visual disturbances. Monitoring visual symptoms in PRES is critical as visual deficits are found in nearly 40% of patients. This paper aims to identify the visual symptoms associated with PRES and determine visual outcomes following treatment. While the symptoms of PRES are alarming, the disease is typically reversible once the cause is eliminated. Our findings suggest that those who present with ocular complaints can be reassured that their symptoms will improve, if not completely resolve.
