摘　　要：对２２名４４只开角型青光眼和２２名４４只正常人眼，用美国Ｄｉｃｏｎ公司，ＴＫＳ－４０００型声控动态视野仪，行３０°、８０个刺激点视敏度检查。结果：（１）视丘视敏度（０～４ｄＢ）：青光眼组占８４０９％；正常眼组占４７７２％，ｘ２检验Ｐ＜０００１；（２）视敏度总数：青光眼为２０１７５７±５７３２；正常眼组为２２５０８４±１１９０，ｘ２比较Ｐ＜０００１；（３）各象限不同圈视敏度比较：青光眼组异常检出率高于正常眼组，Ｐ＜０．００１；（４）青光眼１５°出现Ｓｅｉｄｅｌ氏和Ｂｊｅｒｕｍ氏暗点较正常眼组明显增多；（５）三维立体视野，能够看出青光眼组视野缺损的范围、深度。结论：中央３０°三维立体视野能够检出视敏度异常及视野缺损情况，对青光眼早期诊断及评估预后，提供可靠依据。In order to obtain the early diagnosis and to evaluate the prognosis of glaucoma, a dicon TKS 4000 automated perimeter was used to explore the level of 30 degree viewfield sensitivity in a control group of age and sex-matched normal 44 eyes and 44 eyes of glaucoma. The results showed that viewfield sensitivity of hill (0-4db) was 84.09% in glaucoma compared with 47.92% in the control group (p<0.001); total amount of viewfield sensitivity was 2017.57+57.32 in glaucoma and 2250.84+11.90 in controls (P<0.001); there were more Seidel and Bjerrum dark spots of 15 degree viewfield in glaucoma than in control group; 3-D hill of vision could reveal the range and depth of viewfield defect in glaucoma. We concluded that central 30 degree dynamic viewfield can detect abnormal viewfield sensitivity and viewfield defect, and thus it may be helpful in early diagnosis and to detect the prognosic of glaucoma.
