title: Retinopathy of prematurity (ROP) and indomethacin therapy in premature infants with patent ductus arteriosus (PDA).
abstract: Recent studies suggested that prostaglandins (PGs) may play a role in the pathogenesis of retinopathy of prematurity (ROP). To evaluate if PGs inhibitor, indomethacin, would affect the incidence or severity of the ROP, an analysis was performed on 47 infants who participated in a double-blind controlled study of indomethacin for the closure of PDA. Twenty-three were in the control group and 24 in the indomethacin group. Indirect ophthalmoscopic examinations were performed from about 4 weeks of postnatal age and onward as needed. There was no significant difference between the groups with respect to birth weight, gestational age, postnatal age, Apgar score, and cardiopulmonary status shortly after birth and at the time of study. Six in the control and 2 in the indomethacin group (p = 0.58) developed active ROP; one in each group developed cicatricial ROP. It appears that with current doses of therapy, indomethacin does not increase the incidence or severity of ROP.
