ObjectiveTo evaluate the potential risk factors with incidence and degree of retinopathy of prematurity (ROP) in infants with very low birth weight.MethodsThe clinical data of 130 premature infants with birth weight ≤1500 g recorded in Peking University People′s Hospital from July 2002 to April 2004 were retrospectively analyzed.ResultsThere were 60 infants in ROP group and 70 infants in control group. The mean birth weight and gestational age was (1256.3±196.8) g and (29.583 3±1.543 6) weeks in ROP group, and (1337.8±146) g and (31.217 4±2.430 6) weeks in control group, respectively. In 39 ecdemic infants, 32 were found with ROP (82.1%, 1 with mild and 31 with severe ROP) while in 91 local infants, 28 were found with ROP (30.8%, 15 with mild and 13 with severe ROP). The time of the first examination in infants with mild ROP was (36.062 5±2.909 0) weeks, which was significantly earlier than (59.477 3±33.604 0) weeks in the ones with severe ROP. The time of the first examination and surgery was earlier in non vitrectomy group than in nonvitrectomy group.ConclusionLow birth weight is the high risk factor in ROP. Incidence of ROP is higher in ecdemic infants. The severity of ROP correlates with time of first examination, and the way of surgery is relative to time of the first examination and surgery.(Chin J Ocul Fundus Dis,2005,21:275-277)
