Objective:We compare the differences of the results of visual field examination of the middle or late chronic ACG with normal strategy and top strategy, in order to afford the proof of the first-term diagnose along with the glaucoma examination。Methods:We test visual fields twice among twenty-seven eyes of 21 patients with chronic angle-closure glaucoma with Octopuc101 automatic perimeters Glaucoma test procedures—normal strategy. Among these normal strategy tests, we try once successfully for two phases to gain SF.We also test visual fields twice with top strategy. Patients have a rest for 30 minutes every twice and all these eyes clients are checked on the same day. The Acquiring vision indexes and vision results are saved to be analyzed and compared.Results:Three indexes of visual fields are positive correlation. Mean defects correlation factor is 0.916, P0.026<0.05, mean sensitivities correlation factor is 0.915, P0.028<0.05, loss variances factor is 0.797, P0.000<0.05. Between short-term fluctuation and mean defect is positive correlation, the variance factor is 0.623, P0.006<0.01.The threshold variance of point-point normal strategy is higher than top strategy, but the difference is not statistically insignificant, because the P0.214>0.05. The SF of normal strategy is 2.589±0868, The SF of top strategy is 4.036±1.009, P0.009<0.05。The testing time in the normal strategy is 12.23±3.15min, while it is 3.98±0.55min in the fast strategy。Conclusion:The two ways of visual field examinations can check the defects of the middle or late-term chronic angle-closure glaucoma effectively。The data ofshort-term is positive correlation with the mean defect.。It takes less time to examine using the top strategy,and the patients feel well but the final checking results between the mormal strategy and top stragety are somehow different。
