Screening for retinopathy of prematurity.
OBJECTIVE
A cross sectional (prevalence) study was performed to assess the usefulness and sensitivity of commonly employed criteria to identify infants for routine ophthalmoscopic screening for retinopathy of prematurity (ROP).


METHODS
At a tertiary care centre between 1 January 1992 and 30 June 1998, experienced vitreoretinal specialists screened 438 premature infants for ROP. Retinal maturity and the presence of ROP were determined by indirect ophthalmoscopic examinations.


RESULTS
Of the eligible infants surviving 28 days, 276 (91.7%) of 301 infants with birth weights </=1500 g and 162 (52.3%) of 310 infants with birth weights between 1501 and 2500 g were screened for ROP. 10 (3.9%) of the 310 infants with larger birth weights developed stage 1 or 2 ROP. Two (0.6%) of the 310 infants with larger birth weights developed stage 3 ROP. These two infants progressed to threshold ROP and required treatment.


CONCLUSIONS
Relatively restrictive criteria to identify premature infants eligible for routine ophthalmoscopic screening for ROP may be the cause for some infants going unexamined and their ROP undetected.
