Abstract

Purpose. To investigate the incidence and the severity of retinopathy of prematurity (ROP) in extremely preterm infants born before 28 weeks of gestation in southeastern Turkey. Methods. A retrospective chart review was performed for infants born before 28 weeks of gestation. The following data were reviewed: gender, gestational age (GA), birth weight (BW), zone and stage of ROP, presence of plus disease, and treatment for ROP if needed. Infants were divided into 2 groups according to GA as follows: group 1 included infants of GAs 25 weeks and under; group 2 included infants of GAs less than 28 weeks and over 25 weeks. Results. The incidence of any ROP in the whole cohort, in group 1, and in group 2, was 66.0%, 95.5%, and 58.6%, respectively. Incidence of any ROP was significantly associated with BW and GA ( and , resp.). The overall incidence of type 1 ROP was 35.8% (59.1% in group 1 and 29.9% in group 2). Development of type 1 ROP was independently associated with GA. Conclusion. Any ROP was significantly associated with BW and GA. Extremely premature infants with lower GA were found to be more likely to develop type 1 ROP. BW cannot predict the development of type 1 ROP.
