目的应用视野指数评价不同部位眼眶肿瘤引起视野改变及其相关因素分析.方法回顾性分析对2006年6月至2008年1月在武警总医院眼眶病研究所就诊的30例视野改变的眶内肿瘤患者自动视野计检查结果,分析不同部位肿瘤引起视野改变的类型,以视野指数平均缺损(mean defect,MD)和模式标准差(pattern standard deviation,PSD)为研究指标,采用析因方差分析法,探讨眼眶肿瘤部位对视野的影响.结果析因方差分析结果显示肿瘤是否压迫眼球后壁和肿瘤在眶内位置均是造成MD和PSD下降的因素差异有统计学意义(P＜0.05),但肿瘤在眶内的位置较肿瘤是否压迫眼球后壁更易引起视野指数的下降,差异有统计学意义(P＜0.05).30例患者中2例仅表现为普遍光敏感度降低外,其余28例均存在不同形式的视野缺损.肿瘤位于眶尖引起上述视野改变所占比例最高占71.43％ (20/28).结论眼眶内肿瘤部位是造成视野指数改变的因素,眶尖部肿瘤更易造成视野指数改变,引起局部视野缺损.

Objective To evaluate visual field changes in orbital tumors of different locations and to analyze related factors using of visual field indexes.Methods The automatic perimeter records with visual field changes of 30 patients with orbital tumors were retrospectively analyzed.Patterns of visual field defects caused by different locations of orbital tumors were analyzed.Visual field indexes including mean defect (MD) and pattern standard deviation (PSD) were used to indicate the effect of the location of orbital tumors on visual field.Two-way factorial ANOVA was used in the present study to analysis of visual field changes in patients of orbital tumors.Results Compression of the posterior wall of eyeball and locations in the orbit of tumors could both decrease the visual field indexes (P ＜0.05).However,the latter had more significant effects (P ＜0.05).Two of 30 patients showed decreased on general reduction.The other 28 patients showed different visual field defects.Visual field changes were mostly caused by tumors in the apex (71.43％).Conclusions Location of orbital tumors can lead to visual field changes.Tumors in the apex results in visual field indexes changes mostly and cause local visual field defects.
