【摘要】 目的对极低体重早产儿出生后各因素进行分析,以寻找可能与早产儿视网膜病变(ROP)形成的有关因素及可能影响ROP轻重程度的因素。方法回顾2002年7月至2004年4月我院检查的130例体重≤1500g早产儿的临床资料,并进行统计学分析。结果ROP组60例,正常眼底组70例。ROP组平均出生体重(1256.3±196.8)g及平均孕周(29.5833±1.5436)周,而正常眼底组平均出生体重(1337.8±146)g、平均孕周(31.2174±2.4306)周。39例外地患儿中早产儿视网膜病变32例占82.1%(轻度ROP1例,重度ROP31例),91例北京患儿中早产儿视网膜病变28例占30.8%(轻度ROP15例,重度ROP13例)。轻度ROP的首次检查时间为(36.0625±2.9090)周,明显早于重度ROP(59.4773±33.6040)周。非玻璃体切割组的首次就诊时间及首次手术时间明显早于玻璃体切割组。结论低体重是ROP的高危因素,外地早产儿ROP较多。ROP的严重程度与首次检查时间有关,ROP手术方式与首次检查时间及首次手术时间有关。更多还原

【Abstract】 Objective To evaluate the potential risk factors with incidence and degree of retinopathy of prematurity (ROP) in infants with very low birth weight. Methods The clinical data of 130 premature infants with birth weight ≤1 500 g recorded in Peking University People′s Hospital from July 2002 to April 2004 were retrospectively analyzed. Results There were 60 infants in ROP group and 70 infants in control group. The mean birth weight and gestational age was (1 256.3)±196.8) g and (29.583 3±)(1.543 6) weeks in ROP group, and (1 337.8±)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 non-vitrectomy group. Conclusion Low 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.更多还原
