We examined 32 children one to 15 years after virologically verified neonatal herpes simplex virus infection. Sixteen of 17 (94%) neurologically impaired children had ocular abnormalities compared to three of 15 (20%) neurologically healthy children. Disturbed oculomotor control occurred in 14 children (44%), most of whom were among those with severe handicap. Ocular morbidity was present in 13 (40%) of 32 children: one had cataracts, two had corneal scars, seven had optic atrophy, and nine had chorioretinal scars. The clinically silent chorioretinal lesions were manifest as coarse hyperpigmented areas between the equator and ora serrata. One child had suffered from acute fulminant retinitis. Twelve of 13 (93%) severely handicapped children had impaired vision, mainly because of cortical blindness. Less affected children had normal vision unless corneal scars were present. Long-term observation of patients with neonatal herpes infections is essential because ocular manifestations are not rare, and recurrences may be more common than previously reported.
