Neuroretinitis in childhood.

We report the clinical features and results of laboratory testing of seven children with neuroretinitis, diagnosed on the basis of reduced visual acuity, relative afferent pupillary defect, and distinctive appearance of the fundi. Disc swelling was segmental in five patients with unilateral disease and diffuse in two patients with bilateral disease. Retinal infiltrates were transiently present in two patients. Swelling of the optic disc and peripapillary retina, along with the inflammatory vitritis resolved by 2 to 6 weeks but macular exudates persisted for 3 to 12 months. Two patients developed optic atrophy with permanent visual loss and two patients had visual acuity reduction detected only under low contrast conditions. Cat-scratch disease was implicated as the cause of the neuroretinitis in two patients; the etiology of the remaining cases was not established.
