We examined the psychomotor development of 33 of 61 surviving children, fro
m a: series of 107 consecutive live-born cases with nonimmune hydrops fetal
is. The majority had a normal outcome. Three had a (simultaneous) serious u
nderlying disease (e.g. fetal herpes infection) and had either severe psych
omotor retardation or blindness. Two showed clumsiness and were considered
to have minor neurological dysfunction. We conclude that survivors, especia
lly those with. transient benign intrauterine conditions, such as lymphatic
aetiology have no additional risk to their psychomotor development.
