— The results of a prospective study of low birthweight infants (< 1500 g) identifies those at risk of retinopathy of prematurity (R.O.P.) as being ≤ 1250 g birthweight or ≤ 30 weeks post‐conceptional age (P.C.A.). In these infants the incidence of R.O.P. was 60% (14% grades 3 or 4). in the remainder the overall incidence of R.O.P. was 24%, exclusively grades 1 or 2. Onset of R.O.P. consistently presented at a mean age of 35 weeks P.C.A. (SD 2.25). Routine retinal examination of all infants ≤ 1250 g birthweight or ≤ 30 weeks gestation is recommended between 33 and 37 weeks P.C.A.
