目的　了解V型斜视的病因、临床表现和手术治疗方法及疗效。方法　分析 1 997年 1月至 2 0 0 2年 4月 1 0 2 7例斜视中 1 2 2例V型斜视病例的病史资料及治疗结果。 1 2 2例V型斜视男 62例 ,女 60例 ,最大年龄为 2 8岁 ,最小年龄为 4岁 ,平均年龄 1 1 6岁。所有病例接受三棱镜和 /或同视机九方位斜视角检查 ,上方斜视度与下方斜视度相差 1 5 △ ～ 42 △ ,平均 2 7△ 。根据有无垂直肌肉功能异常分别选择垂直肌肉手术或 /和水平肌肉移位 ,包括下斜肌后徙、上斜肌折叠、内外直肌后徙或联合上下移位。术后随访时间 1～ 1 8月 ,平均 9月。结果　V型斜视占同期斜视病例的 1 1 88%。其中V型外斜视 79例 (65 % ) ,V型内斜视 3 8例 (3 1 % ) ,原在位正位的V型斜视 5例 (4 % )。引起V型斜视的常见原因为垂直肌肉功能异常 (86% ) ,包括原发性下斜肌功能过强 (4 5 % )、先天性上斜肌麻痹(3 7% )、上直肌不全麻痹 (4 % ) ,水平肌肉附着异常 (1 4% )。手术治疗 87%获得满意效果 (上方斜视度与下方斜视度相差小于 1 5 △ ,水平斜视度小于 1 0 △)。结论　V型斜视是一种常见的斜视类型 ,发病原因以斜肌功能异常为主 ,常合并水平斜视 ,外斜视多于内斜视。根据引起V型斜视的病因选择不同的手术方式可获得满意的手术结果 Objective To understand the etiology, clinical manifestations, surgical treatment and efficacy of V-type strabismus. Methods The data of history and treatment of 122 cases of V-type strabismus in 1027 cases of strabismus from January 1997 to April 2002 were analyzed. There were 62 cases of V-type strabismus and 60 cases of female with a maximum age of 28 years. The minimum age was 4 years and the average age was 116 years. All patients underwent prism and / or synoptophore nine oblique viewing angle examination, the top of the strabismus and the bottom of the strabismus difference of 15 ~ 42 △, an average of 27 △. Vertical muscle surgery or / and horizontal muscle displacement were selected based on the presence or absence of vertical muscular dysfunction, including posterior oblique muscle posterior migration, superior oblique muscle posterior, posterior rectus muscle migration, or joint up and down shift. Postoperative follow-up 1 ~ 18 months, an average of 9 months. Results V-strabismus accounted for 1 1 88% of strabismus cases in the same period. Among them, 79 cases (65%) were type V exotropia, 38 cases (31%) were type V estropia, and 5 cases (4%) were orthostatic type V-type strabismus. Common causes of V-type strabismus include abnormalities in vertical muscle function (86%), including hyperextension of the primary inferior oblique muscle (45%), congenital superior oblique paralysis (37%), paralysis of the upper rectus abscess (4%), abnormal level of muscle attachment (14%). Surgical treatment of 87% of satisfactory results (above the degree of strabismus and inferior strabismus below the less than 1 5 △, horizontal strabismus less than 1 0 △). Conclusions V-type strabismus is a common type of strabismus. The cause of the disease is mainly oblique dysplasia, often associated with horizontal strabismus and exotropia more than esotropia. According to the cause of V-type strabismus choose different surgical methods can be satisfactory surgical results
