title: Visual loss caused by pseudotumor cerebri in an infant on peritoneal dialysis.
abstract: Infants with chronic renal insufficiency have multiple risk factors for developing pseudotumor cerebri (PTC) and are at particular risk for being diagnosed with PTC late, because of their inability to express symptoms. We describe a 13-month-old infant dependent on peritoneal dialysis, without evidence of central nervous system infection or inflammation, who developed acute vision loss secondary to PTC. Signs of PTC in infants include torticollis, inattentiveness, inability to track, facial paresis, or new-onset strabismus. Physicians responsible for the care of children with renal failure should be aware of the potential for PTC, as the diagnosis should be made as early as possible to prevent permanent visual loss.
