DUSN, diffuse unilateral subacute neuroretinitis probably associated with a larva parasite. In one of these cases, the manifestation was bilateral; EBV, Epstein-Barr virus; CMV, cytomegalovirus.
*In these cases, the uveitis was associated with the presence of visceral larva migrans other than Toxocara (Oxyuris or ascariasis). The presence within the eye of living larvae was not documented in any of these cases.
†These bacteria were isolated from the anterior chamber in children with unilateral disease and were probably associated with an unsuspected antecedent penetrating trauma in these eyes.
‡The bacteria were isolated from the urine of children suffering from chronic urinary tract infection and bilateral uveitis.
