Purpose : To describe the demographic and clinical and characteristics and risk factors of neonates with retinopathy of prematurity (ROP) detected in the ROP screening programs in Colombia

Methods : Cross-sectional analytical retrospective observational study. Records of neonates from Neonatal Intensive Care Units (NICU) were screened for ROP between 2015 and 2020. The screening criteria were: 32 or less gestational age (GA) in weeks or 1,500 grams or less of birth weight (BW). Indirect ophthalmoscopy was performed by retina specialists or pediatric ophthalmologists. The first examination was performed between the fourth and sixth weeks of life, with repeat examinations until retinal vascularization was complete. Eyes were graded for ROP severity based on the Classification International ROP (ICROP). A database was created in which demographic variables were recorded, maternal and neonatal risk factors, ROP classification and treatment.

Results : The records of 1,691 infants were reviewed and included 727 (43%) males and 94 (57%) females. Mean gestational age was 32.44 ± 2.6 weeks (range 24-39) and mean birth weight was 1,536 ± 404 grams (range 650-3,700). Mean postmenstrual age at the time of examination was 36.72 weeks (range 26-60). The mean gestational age of preterm infants with ROP was 28.66 ± 2.87 weeks (range 24-38); the mean birth weight was 1,230 ± 538 grams (range 650-2,100).
The proportion of ROP in less than 1,000 grams was 42.1%, and of them, 42.6% presented affection in zones I and II.
The most frequent risk factors were sepsis and suplemmentary oxygen and 8.6% of neonates with ROP required surgical treatment.

Conclusions : The global prevalence of ROP was 17.5%, with a mean gestational age of 28.66 weeks and mean mean birth weigh of 1,230 grams.
