摘要
目的应用光学相干断层扫描技术(OCT)对双眼近视散光性弱视儿童视盘周围视网膜神经纤维层(RNFL)平均厚度与黄斑中心凹厚度进行测量,为进一步探讨不同类型弱视的发病机制提供依据。方法选取近视散光性弱视儿童15例(散光性弱视组,30只眼)及同龄正常儿童15例(对照组,30只眼),进行视网膜OCT检查,记录两组视盘周围RNFL的平均厚度和黄斑中心凹厚度,并进行比较。结果两组视盘周围RNFL平均厚度及黄斑中心凹厚度比较差异均有显著性(t=2.457、2.056,P<0.05)。结论近视散光性弱视儿童视盘周围RNFL平均厚度与黄斑中心凹厚度较正常同龄儿童明显增厚。散光可能是通过影响视网膜形态结构而导致弱视形成。
Objective To assess and compare the thickness of peripapinary region retinal nerve fiber layer and the fovea in children with astigmatic amblyopia and normal children,and provide a basis for further study of the pathogenesis of different types of amblyopia. Methods OCT was performed in 15 children with astigmatic amblyopia(amblyopic group,30eyes),15 normal children(normal group,30eyes).The thickness of peripapillary region retinal nerve fiber layer and the fovea was measured and compared between the two groups. Results There was a significant difference between the two groups with regard to the mean thickness of peripapillary region RNFL and fovea(t=2.457,2.056;P〈0.05). Conclusion The thickness of RNFL and fovea in children with astigmatic amblyopia was thicker than those with normal eyes.Astigmatism may induce amblyopia through affecting the morphosis of retina.
