Abstract: 目的分析影响经手术治疗鞍区脑膜瘤视力预后的因素.方法收集以视力障碍为首发症状的鞍区脑膜瘤71例.先以双眼为单位,根据视力损伤评分表对其术后与术前的视力视野进行评分,以评分差来衡量预后并进行多重回归,筛选影响双眼视力预后的因素.再以单眼为单位,将术后视力以0.05为界分为2组,与其影响因素行单因素分析,再以0.05、0.5和1.0为界分为4个等级,进行有序分类logistic回归,分析影响单眼术后视力的因素.结果双眼视力的综合预后受其术前的评分及肿瘤切除程度的影响(B=-0.109,P<0.05和B=7.408,P<0.05);单眼的术后视力与其术前视力呈正相关(B=4.255,P<0.01)与视乳头的病变程度及视神经的受累程度呈负相关(B=-0.943,P<0.01和B=-0.830,P<0.05);术前视力低于0.05、视乳头苍白萎缩或视神经管受累的眼球术后视力恢复到0.05以上的比例极小.结论术前的视力、视乳头的病变程度、视神经的受累程度及肿瘤的切除程度对术后的视力恢复有影响.
