AIM: To understand the epidemic situation of retinopathy of prematurity in Sanya region and its related factors analysis so as to provide a reference for the prevention of the disease in this region.

METHODS: A total of 243 premature infants(486 eyes)with gestational age of less than 36 weeks and 35 cases of full moon(70 eyes)who were delivered in Sanya Maternal and Child Health Care Hospital from January to December 2019 were selected as the research objects. Fundus screening was performed. And the incidence of retinopathy of prematurity was calculated according to the diagnostic criteria, and univariate and multivariate Logistic regression analysis was performed on the related data of the mothers before and during pregnancy.

RESULTS: There was no retinopathy in the whole moon, but 36 cases of premature infants with retinopathy of prematurity. And the incidence of the disease was 14.8%(36/243). Among them, about half(58.3%)of the children with stage Ⅰ disease. Followed by stage Ⅱ disease(30.6%), stage Ⅲ disease(8.3%)and stage Ⅳ disease(2.8%), no stage Ⅴ disease were found. Meanwhile, 2 children with threshold lesions(5.6%). Except for the gestational age, there were no significant differences in the related factors of menstruation, gestational age, gestational births and pregnancy complications between full-term and normal preterm mothers(P>0.05), but compared with the mothers of premature infants, the differences were statistically significant(P<0.05). The irregular menstruation, older pregnancy, gestational age short, polyembryony, eclampsia, PIH, diabetes and perinatal infection were independent risk factors for retinopathy of prematurity(P<0.05).

CONCLUSION: The incidence of retinopathy of prematurity is high in Sanya, which should be paid great attention. At the same time, there are many influencing factors. It is an effective method to reduce retinopathy of prematurity in this area that menstrual conditioning before pregnancy, avoid advanced pregnancy, term birth, monocyesis and control pregnancy complications.
