Sudden bilateral vision loss as the sole manifestation of posterior reversible encephalopathy syndrome from acute uremia: Clinical case report.

BACKGROUND

Posterior reversible encephalopathy syndrome (PRES) is a cliniconeuroradiological entity associated with vasogenic edema. Symptoms may include headache, seizures, altered mental status, and visual impairment. Patients with PRES generally present with neurological deficits.

UNASSIGNED

Here, we report an unusual case of a 42-year-old man who presented with sudden bilateral vision loss without any other neurologic symptoms.

UNASSIGNED

He was diagnosed with PRES secondary to acute uremia.

RESULTS

Our patient experienced a dramatic improvement in visual acuity, blood chemistry values, and magnetic resonance imaging findings following repeated hemodialysis.

CONCLUSIONS

Sudden bilateral vision loss may be the sole manifestation of PRES, particularly in patient with risk factors for PRES. Awareness of this variation of the clinical symptoms of PRES is important to facilitate its recognition.
