    Abstract:
    PURPOSE: We aimed to determine applicable guidelines for screening of retinopathy of prematurity (ROP), and evaluate the contribution of risk factors for severe ROP. METHODS: A prospective cohort study of neonates with a gestational age (GA) < 34 weeks or birth weight < 2000g who were admitted to the Neonatal Intensive Care Unit (NICU) of a tertiary level hospital was conducted. The study group was classified into three groups according to eye examination findings as no ROP, mild ROP and severe ROP. RESULTS: Of the 700 neonates screened, the frequencies of ROP for any stage and severe ROP were 32.7% and 3.1%, respectively. Laser photocoagulation was needed in 9.6% of neonates with ROP. None of the neonates with a GA ≥ 31 weeks required treatment. Any ROP was detected in 199 (53.6%) of the babies < 32 weeks (n = 371), 22 (5.9%) of whom were treated with laser photocoagulation. Independent risk factors for severe ROP in babies < 32 weeks GA were birth weight, duration of mechanical ventilation and patent ductus arteriosus (PDA). CONCLUSION: This is the largest prospective cohort study including infants younger than 34 weeks GA from Turkey. Our data which belongs to the last 1-year period shows lower incidence of severe ROP when compared to previous reports from Turkey. According to our data, screening babies smaller than 32 weeks GA or 1500g birth weight seems reasonable. In the presence of long duration of mechanical ventilation and PDA, screening should be intensified.
