324例A-V型斜视的临床特征

目的探讨A-V型斜视的临床特征。设计回顾性病例系列。研究对象A-V型斜视患者324例。方法对2009年1月至2010年1月于北京同仁医院眼科门诊就诊诊断为A-V型斜视的患者324例,其中A型斜视114例,V型斜视210例。方法对所有患者的临床资料进行分析,观察其发病特点、斜视度、斜视类型、眼球运动特点和双眼视觉等临床特征。主要指标发病年龄、就诊年龄、斜视度分布、伴随发生的斜视类型、眼球运动异常和双眼视觉。结果 A型斜视患者和V型斜视患者中,1岁内发病者分别为70例(61.40%)和109例(51.90%)(P=0.07),在3~9岁间就诊者分别为18例(15.78%)和127例(60.48%)(P<0.01)。A型斜视患者中有25例(21.93%)是知觉性斜视,而V型斜视中知觉性斜视仅有3例(1.43%);在V型斜视中,先天性斜视有43例(20.48%),而A型斜视中仅有6例(5.26%)。A型斜视中48例(42.11%)患者单侧上斜肌亢进,64例(56.14%)患者双侧上斜肌亢进,1例(0.88%)患者不伴斜肌运动异常;V型斜视中,103例(49.05%)患者单侧下斜肌亢进,93例(44.29%)患者双侧下斜肌亢进,9例(4.29%)患者不伴斜肌运动异常。A型斜视患者中仅11例(9.65%)有同视机一级功能,所有患者均无远、近立体视。V型外斜视中有26例(12.38%)有近立体视,24例(11.43%)有不同程度的同视机立体视。结论 A-V型斜视患者发病年龄早,伴知觉性斜视多见,而V型斜视多伴发先天性斜视;多数A-V型斜视伴有斜肌运动异常;A型斜视较V型斜视更易损伤双眼视觉。
