Abstract
Posterior reversible encephalopathy syndrome (PRES) is a poorly understood, severe neurological condition secondary to impaired auto-regulation in the vertebrobasilar brain circulation resulting in subcortical vasogenic oedema distributed mainly in the white mater of the parietal and occipital lobes. Affecting optic radiation, PRES leads to visual deterioration, e.g. blurred vision, different types of vision field deficits, or even total blindness. The symptoms have a sudden onset and rapid progression, but are usually at least partially reversible. To bring this rare disorder closer to ophthalmologists, we present two cases of patients diagnosed with PRES.
