【Abstract】 Objective To analyze the risk factors of retinopathy of prematurity (ROP). Methods Ocular fundi of 132 premature infants (264 eyes) (age of gestation<37 weeks and birth weight<2500g) were examined from the first week after birth. According to the international classification of retinopathy of prematurity, ROP was diagnosed and classified. The occurring time of ROP was noticed, and the risk factors of ROP, such as the age of gestation birth weight and oxygen concentration and etc, were observed. Results Over a period of half a year follow up, Thirty-one infants with ROP were diagnosed from 132 premature infants, the incidence of ROP was 23 5%. The results showed the shorter the gestation, the lower the birth weight, the higher the oxygen concentration, the higher the incidence of ROP. Conclusion We emphasize that ocular fundi of premature infants must be examined.更多还原
