儿童V型斜视手术疗效观察

Clinical curative effect observation ofsurgical treatment of V-strabismus in children

目的探讨儿童V型斜视的临床特征及手术疗效。方法:对2014年6月至2016年6月于我院收治的54例V型斜视,了解其发病年龄、斜视度、斜视类型、眼球运动特点和眼底表现。其中52例采用下斜肌减弱联合水平直肌移位术,1例采用水平直肌垂直移位半个肌腱,1例单纯行水平直肌移位术,观察其不同术式前后眼位及斜肌功能的变化。结果:V型斜视发病年龄集中在2岁以内,其中外斜V征46例,内斜V征8例,53例伴有下斜肌亢进,52例伴有眼底外旋,8例有代偿头位。8例有近立体视,7例有不同程度的同视机立体视。采用不同术式后V征治愈者47例,代偿头位均有改善,眼底外旋也均有改善。结论:V型斜视病因复杂,尽早根据相应体征采用不同术式可获得满意的手术效果。

Objective To investigate the clinical features and surgical results of V-strabismus in children.Methods Fifty-four cases of V-strabismus from June 2014 to June 2016 in our hospital were observed,the age of onset,strabismic degree,types of strabismus,ocular movement characteristics,fundus photography,the change of eye position and oblique function before and after different operations.Fifty-two cases wereundergo the surgery of inferior oblique weakening joint horizontal muscle,1 case of horizontal rectus vertical displacement of half tendon,1 case of horizontal rectus transposition only.Results The age of onset of V-strabismus was less than 2 years,including 46 cases of external oblique V sign,8 cases of internal oblique V sign,53 cases with inferior oblique hyperfunction,52 cases with fundus external rotation,and 8 cases with compensatory head position.Eight cases had nearly stereoscopic vision,7 cases with different degree of stereopsis.After different methods of operation,V sign of 47 cases were cured,the compensatory head position was improved,and the external rotation of ocular fundus was improved.Conclusions The etiology of V strabismus is complicated,and satisfactory results can be obtained by using different surgical procedures according to the corresponding signs as early as possible.
