目的：应用动态视野仪检查垂体瘤患者的视野改变。方法：采用美国TRS-4000型声控动态视野仪，对60例垂体瘤患者的120只眼，行60°、72个刺激点视敏度检查，并与其CT、MRT检查做对照分析。结果：60例垂体瘤患者术前视野检查阳性检出率为68.33％，结果正常者占31.6％。而CT、MRI检查阳性检出率为70％，正常者4例，占6.77％，经统计学检验两者结果有则致性，X2=0.08，P>0.05。虽然视野的阳性检出率低于CT及MRI，但视野阳性的诊断价值是100％，无假阳性。120只眼有49只眼为偏盲，占40.83％，偏盲以中线对劈为特点，偏盲多于缺损、暗点和全盲。结论：垂体瘠患者的视野改变有偏盲、暗点、缺损等，其部位、性质对垂体瘤的早期诊断、手术定位及进路均有重要意义。

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.
