良性特发性眼睑痉挛患者的屈光状态及分析

The refractive state of patients with benign essential blepharospasm

目的分析良性特发性眼睑痉挛患者的屈光状态分布情况。方法选取2017年1月至2018年12月温州医科大学附属眼视光医院收治的良性特发性眼睑痉挛患者63例(120眼),为眼睑痉挛组;另择同期为求老视镜验配者63例(120眼)为正常对照组。观察并比较两组患者各类屈光状态分布情况。结果眼睑痉挛组以单纯远视眼最多(占36.7%),其次为正视眼(29.2%)、远视合并散光眼(11.7%)。眼睑痉挛组与正常对照组屈光状态的分布差异有统计学意义(P<0.05)。两组大部分屈光不正均为低度数。眼睑痉挛组与正常对照组球镜度数分布、柱镜轴向分布比较差异均无统计学意义(均P>0.05),柱镜度数分布差异有统计学意义(P<0.05)。结论良性特发性眼睑痉挛患者屈光状态以远视合并或不合并散光为主,与正常人群相比柱镜度数分布存在差异。

Objective To analyze the refractive features of benign essential blepharospasm(BEB)patients.Methods Sixty three patients(120 eyes)with BEB treated in our hospital from January 2017 to December 2018 were enrolled in the study and 63 individuals(120 eyes)visiting hospital for presbyopic optometry were recruited as the control group.The refractive state was recorded and compared between two groups.Results Among BEB eyes,the distribution of refractive state was hyperopia(36.7%),emmetropia(29.2%)and compound hyperopic astigmatism(11.7%),which was significantly different with the control group(P<0.05).Most of the refractive errors were low degrees in both groups.There were no statistically significant differences between the two groups in the distribution of spherical degree and the axis of astigmatism(both P>0.05),but the difference in the degrees of astigmatism was statistically significant(P<0.05).Conclusion The distribution of refractive state in patients with BEB was mainly hyperopia with or without astigmatism.The distribution of astigmatism is different from that of the normal subjects.
