SOME OF THE RISK FACTORS FOR RETINOPATHY OF PREMATURITY

Retinopathy of prematurity (ROP) remains the main cause of visual impairment in preterm infants. The study was aimed to assess the impact of some of the risk factors (gestational age, body weight of children at birth, associated diseases in children, maternal age at delivery, maternal smoking during pregnancy, multiple pregnancies) on the occurrence of ROP in the sample of premature infants. We statistically processed the results (Student’s t test and the χ2 test) of 93 preterm infants of both sexes: 39 boys and 54 girls, examined by indirect ophthalmoscope (Haine 500, Germany) in mydriasis. The examination included all premature neonates with birth weight ≤ 2000g and/or gestational age ≤37 weeks, as well as neonates >37 weeks which have associated risk factors (oxygen, ventilation, sepsis, etc). Among 93 premature infants, with normal findings on the retina there were 72 children (77.42%), while in 21 (22.58%) children we found ROP. Ophthalmological findings: the first stage of ROP was found in 15.05%, the second stage of ROP in 2.15% and third stage of ROP in 5.38% of the examined children. There were no patients with an aggressive form of ROP. Children with ROP were statistically of lower gestational age - 32.10 ± 2.70 compared to children without ROP - 35.37 ± 1.72 (p<0.001). Children with ROP had at birth significant lower body weight of 1741g ± 579.19 than children without ROP - 2168.75 ± 528.58 (p<0.01). Mothers of the children with ROP were, at the time of giving birth, over 29 ± 6.09 years old compared to mothers of children without ROP who were 26.42 ± 5.75 years old (p=0.0773). The presence of other diseases was significantly more prevalent in children with ROP 52.38% vs. 2.78% (p
