Incidence of retinopathy of prematurity in New Zealand.

The incidence of retinopathy of prematurity has been prospectively assessed in very low birthweight infants born in one year in New Zealand. A total of 26 (11%) surviving infants with birth weight 1000-1499 g had acute retinopathy. Forty one (49%) surviving infants with birth weight 500-999 g had acute retinopathy and of these six (7%) became bilaterally totally blind.
