【摘要】：目的比较青光眼视野检查程序的正常策略(Normal)和快速策略(TOP)对中晚期慢性闭角性青光眼(chronic angle-closure glaucoma chronic ACG)病人视野检查结果的差异,为青光眼的诊断和随诊提供依据。方法用Octopus 101自动电脑视野计对21例青光眼患者共27眼分别用青光眼检测程序(G2)的正常策略检查程序(Normal)检查2次,其中一次正常策略检查2相,获得SF值。再用快速策略(TOP)检查程序检查2次,每2次之间都要休息30min,而且所有受检眼在同一天内完成上述检查。将两种方法所得视野指数及视野结果储存进行分析比较。结果2种策略视野检查的3种视野指数MD、MS、LV均呈正相关,平均缺损(mean defect, MD)的相关系数是0.916,P值为0.0260.05,平均光敏感度(mean sensitivity, MS)的相关系数是0.915,P值为0.0280.05,丢失方差(loss variance,LV)的相关系数是0.797,P值为0.0000.05。短期波动(SF)和平均缺损之间呈正相关其相关系数是0.623,P值为0.006.0.01。点对点阈值变异正常策略略低于快速策略,但P值为0.2140.05,差异无统计学意义；正常策略的SF值为2.589±0.868,快速策略的SF值为4.036±1.009,P值0.0090.05,差异有意义；正常策略程序检测所用时间是12.23±3.15min而快速策略程序是3.98±0.55min。结论2种视野检查法均能有效检测中晚期慢性闭角性青光眼的视野缺损。短期波动与平均缺损呈正相关。快速策略检查所用时间短,患者不易疲劳,但检查结果与正常策略间存在差异。
[Abstract]:Objective to compare the difference between normal and rapid strategy of glaucoma visual field examination (angle-closure) in patients with chronic angle-closure glaucoma chronic (ACG), and to provide evidence for the diagnosis and follow-up of glaucoma. Methods 27 eyes of 21 patients with glaucoma were examined with Octopus 101 automatic computer visual field meter. The normal strategy examination procedure of G2) was performed twice, including 2 phases of normal strategy examination. The SF value was obtained and then checked twice with the quick strategy top check procedure, with a rest of 30 minutes between each two times, and all the eyes were examined in the same day. The visual field index obtained by the two methods and the results stored in the visual field were analyzed and compared. Results there was a positive correlation between the three visual field indices (MDM MS LV) of the two kinds of strategic visual field examination. The correlation coefficient of mean defect (MD) was 0.9260.05, the mean sensitivity of light sensitivity was 0.0260.05, the correlation coefficient of MS) was 0.0280.05, the correlation coefficient of missing variance loss variation (LVV) was 0.797hp was 0.0000.05.The correlation coefficient between the short term fluctuation SFV and the average defect was positive correlation. The correlation number is 0.623 P = 0.006.0.01. The normal strategy of point to point threshold variation is slightly lower than that of fast strategy. The SF value of normal strategy was 2.589 卤0.868, and that of fast strategy was 4.036 卤1.009 (P 0.0090.05), the time of normal strategy test was 12.23 卤3.15min, and that of rapid strategy procedure was 3.98 卤0.55min. but P value was 0.2140.05, and the SF value of normal strategy was 2.589 卤0.868, and that of fast strategy was 4.036 卤1.009 (P = 0.0090.05). Conclusion both visual field examination methods can effectively detect the visual field defect in middle and late stage chronic closed angle glaucoma, the short-term fluctuation is positively correlated with the average defect, the time for rapid strategic examination is short, and the patient is not easy to fatigue. However, there were differences between the results of the examination and the normal strategy.
