先天性白内障二期人工晶状体植入术后眼轴长度变化的研究

Changes of axial length after second term intraocular lens implantation in children after congenital cataract extraction

摘要:

目的:探讨婴儿出生3mo内先天性白内障摘除二期人工晶状体植入术后眼轴的变化。方法:对13例22眼(4例单眼)出生后3mo内的患儿行白内障摘除联合后囊膜连续环形撕囊及前段玻璃体切割手术,在2.5岁时行二期IOL植入手术并连续观察。分别在3,4,5岁时测量术眼眼轴长度;同时选择年龄和性别相匹配的同龄正常儿童作为对照组,比较两组之间的差异。结果:各年龄段术后患儿平均眼轴长度分别为22.41±1·75,23.16±1.42,23.73±1.37mm。与同年龄对照组进行比较,比正常儿童眼轴长,差异有统计学意义(P<0.05)。结论:婴儿早期行先天性白内障摘除并在2.5岁时植入IOL后,到5岁阶段,眼轴长度较同龄正常儿童眼轴发育快。

Abstract:

AIM:To observe the changes of axial length after second term intraocular lens(IOL) implantation in infants after congenital cataract extraction.METHODS: A consecutive case series of total 13 aphakic infants (22 eyes including 4 unilateral eyes), who had undergone IOL implantation surgeries at 2.5 years of age, were included. Patients were divided into 3 groups based on their ages at follow-ups: 3-year group, 4-year group and 5-year group. The axial lengths in each follow-up were measured. The changes of axial length were analyzed and compared with those of normal age-gender-matched children.RESULTS: The mean axial lengths from 3-year group to 5-year group were 22.41±1.75mm, 23.16±1.42mm and 23.73±1.37mm respectively.There was statistically significant difference compared with those of normal age-gender-matched children (P<0.05) .CONCLUSION: The axial length of young children, following second term IOL implantation at 2.5 years of age, was longer than normal children in the period of 5 years of age. 
