The Prevalence of Retinopathy of Prematurity and Relationship with Gestational Age and Birth-Weight

In this study, we aimed to determine the incidence of retinopathy of prematurity (ROP) and the risk factors especially gestational age (GA) and birth weight (BW) associated with its development. Three hundred eighty-two consecutive infants were included in the data analysis. BW and GA were evaluated according to the development of ROP. ROP was detected in 133 infants (35%) of 382 infants; of those 58% had stage 1 disease, 10% had stage 2 disease, 22% had stage 3, 2% had stage 4a, 1% had stage 4b, 1% had stage 5 and 8% had aggressive posterior retinopathy of prematurity disease. Low BW and low GA was statistically associated with ROP. In conclusion,  the incidence of ROP was detected at 35%. ROP is known to be a multifactorial disease, the major risk factors are low GA and low BW.
