“…Studies conducted in developed countries suggest that infants born at ≥32 weeks’ gestation are not at risk of developing ROP 9. The percentage of any ROP in infants with BW ≤1500 g observed in our study is comparable to results from other middle-income countries such as Taiwan, Brazil and Iran, where the incidence of ROP ranged between 33% and 45% 3 13 14. The incidence of any ROP in infants with GA ≤32 weeks has been reported to be 36–50% in our country 15–18…”

“…Our results are similar to those of an investigation carried out in Tehran (13); this may be explained by the similar facilities and relatively equal levels of prenatal care at the centers. In a recent study performed in Babol, northern of Iran, the incidence of ROP was 47.3% for infants with gestational age of ≤ 32 weeks and 33.3% for infants with birth weight of < 1500 g, whereas ROP developed in 2 infants (6%) with birth weight of > 2000 g (14). Karkhane et al found that 34.5% of premature infants had different stages of ROP.…”

BackgroundRetinopathy of prematurity (ROP) is a vascular retinal disease that can cause low vision or blindness and affects premature newborns of very low birth weight.ObjectivesThe purpose of this study was to determine the incidence and risk factors for ROP among very premature infants in Mashhad located northeast of Iran.Material and MethodsIn this cross-sectional study performed between 2006 and 2010, predisposing factors and severity of ROP were evaluated in very premature infants (<32 gestational weeks). Consecutive infants were enrolled at birth and screened for ROP at 4 to 6 weeks of age by indirect ophthalmoscopy. Severe ROP was defined as stage 4 or 5. Chi-square, Student’s t-, and Fisher’s test were used for statistical analysis.ResultsThe incidence of ROP was 26.2%. Significant differences between the ROP and control groups were observed, these include; gestational age, sex, birth weight, Apgar score, durationof parenteral nutrition, oxygen therapy, phototherapy, maximum PaO2 and minimum SpO2 (P < 0.05). Severe ROP was seen in 31.4% (11/32) of ROP cases (5.4% of newborns).ConclusionThe incidence of ROP is relatively high in this region. Risk factors for ROP among very premature infants include hypoxia, severe hyperoxia, relatively low blood SPO2, gestational age, birth weight, and Apgar score.

“…Recent studies report many systemic risk factors (respiratory distress syndrome, sepsis, necrotizing enterocolitis, intraventricular hemorrhage, and blood transfusion for neonatal severe anemia) associated with ROP [7–9]. The probable cause of the severity of ROP in ELBW infants could be associated with the risk factors stated above.…”

BackgroundThe aim of this study was to identify the incidence of severe retinopathy of prematurity (ROP) requiring laser treatment and the overall incidence of ROP in extremely low birth weight (ELBW) infants, and to evaluate the associated risk factors for developing severe ROP in ELBW infants in Turkey.Material/MethodsThis retrospective, case-control, tertiary care-hospital based study included 235 ELBW infants screened for ROP. The incidence of the onset of ROP and severe ROP requiring laser treatment were assessed. The relationship between various clinical risk factors, and the development of severe ROP and onset of ROP were analyzed using univariate analysis and multivariate logistic regression analysis.ResultsThe overall incidence of any stage ROP and severe ROP requiring laser treatment in ELBW infants was 75.5% and 38.7%, respectively. Severe ROP requiring laser treatment in ELBW infants was significantly associated with various independent risk factors, including blood transfusion (P=0.002), gestational age at birth (P<0.001), gestational weight at birth (P=0.001), culture-proven sepsis (P=0.047).ConclusionsThe severity of ROP may increase as weight at birth and gestational age at birth decrease, and in those with culture-proven sepsis as well as in those that receive blood transfusion. Clinicians should be aware of the presence of these risk factors when treating ELBW premature infants. Early detection and prevention of sepsis and reducing the number of blood transfusions may decrease the incidence of severe ROP requiring laser treatment.

Incidence and Risk Factors of Retinopathy of Prematurity in Babol, North of Iran

Abstract: The results show that the incidence of ROP is relatively high in our region. Low GA, low BW, phototherapy, ARDS, and blood transfusion were the main risk factors for development of ROP.
