二极管激光光凝治疗早产儿视网膜病变

Treatment of diode laser for retinopathy of prematuriy

目的 探讨二极管激光光凝治疗早产儿视网膜病变 ( retinopathy of prematurity,ROP)的效果。 方法 6 8例出生时妊娠期不足 32周、体重小于 15 0 0 g的早产儿 ,出生后 6～ 7周开始 ROP检查 ,确诊 ROP阈值病变后 48h内均给予经瞳孔二极管激光光凝治疗 ,激光光凝治疗后随访 4～ 6个月。 1只眼因激光光凝治疗后 1个月发现局部视网膜脱离 ,给予巩膜环扎手术治疗。手术后随访 3个月。确诊 ROP阈值病变眼均在出生后 4个月时进行屈光状态的散瞳检影检查。 结果 6例 12只眼发现 ROP阈值病变。发生 ROP阈值病变的年龄平均为生后 ( 10± 2 .89)周 ( 6～ 14周 )。经瞳孔二极管激光光凝治疗后 ,ROP解剖治愈 (视网膜在位 )率91.6 7% ;巩膜环扎手术眼手术后随访视网膜在位。散瞳检影检查巩膜环扎手术眼屈光度为 - 14.5 0 D,其余 11只眼等值球镜平均为 ( - 2 .89± - 1.86 ) D。 结论 二极管激光光凝可成功地治疗 ROP阈值病变。

ObjectiveTo evaluate the effect of the treatment of diode laser for retinopathy of prematuriy (ROP). MethodsSix-eight premature infants, with the gestation <32 weeks and birth weight < 1 500 g, were examined 6-7 weeks after birth. The infants suffering from threshold ROP were treated by diode laser through a binocular indirect ophthalmoscope within 48 hours after the confirmation of diagnosis, and with the follow-up of 4～6 moths. Retinal detachment was found in 1 eye 1 month after laser treatment, and scleral encircling operation was performed on the eye which was followed up for 3 months after the operation. Cycloplegic refractive examination was performed on the eyes with threshold ROP 4 months postnatally to determine the presence of refractive errors. ResultsSix infants (1) eyes were diagnosed as with threshold ROP.The average age of the occurrence of threshold ROP were (10±2.89) (ranging from 6 to 14 weeks) weeks postnatally. The successful rate of diode laser treatment was 91.67%. Retina was flat in one eye treated by scleral encircling operation. Refractive errors of the eye treated by scleral encircling operation was -14.5 D, and the median spherical equivalent errors in other 11 eyes was (-2.89±-1.86) D. ConclusionThe treatment of diode laser is effective for threshhold ROP.
