60例垂体瘤患者术前视野改变
Preoperatiye visual field changes of 60 ases of pituitary tumour
摘要
Abstract
Objeetive:To locate the location and range of neoplasms in visual path using dynamic perimeter. Methods:visual acuity with 60. and 72 dots were checked in 60° and 72 dots were checked in 60 cases of pituitary tumnour using American TFS-4000 type sound control dynamic perimeter as compared with CT and MRI checking. Results:Tbe positive rate of visual field before operation was 68. 33% and the negative rate was 31.6%. The positive rate of CT and MRI was 70% and 4 cases were normal (6. 77%). Statistic checking showed coherence between the two results, χ2=0.08, P>0. 05. Although the positive rate of visual field was lower than that of CT and MRI, the diagnostic value of positive visual field was 100% and there was no false poitiveness. 49 eyesof the 120 eyes showed hemianopsia (40. 83%), it was characteristically divided by the central line. The number of hemianopsia was more than defect, blind dots and full blind. Conciusion:Tho visual field changes of pituitary tumour showed bemianopsia, blind dots, defect etc.. Their location and uature have important significance inearly diagnosis, surgical location and surgical path.关键词
