目的探讨模式偏差（PD）值在青光眼患者白内障视野补偿中的应用价值。比较两组患者手术前后Humphrey视野分析仪的平均总偏差值（mTDs）和平均PD（mPD）。在成功的白内障手术前（VF前）和手术后（VF后）6个月进行视野测量。计算VFpre的mPD或mTD值与VFpost的mTD值之间的差值（以mPD/mTD表示），并探讨真性昏迷性视野损害或白内障的程度（分别以mPD和mTD表示）对该差值的影响。结果VFpre的mTD与VFpost的mTD之间有显著性差异（P < 0.05）。
Background/aims To study the efficacy of pattern deviation (PD) values in the estimation of visual field compensating the influence of cataract in eyes with glaucoma.Methods The study subjects comprised of 48 eyes of 37 glaucoma patients. Mean total deviation value (mTDs) on Humphrey Field Analyzer after cataract surgery was compared with mean PD (mPD) before the surgery. Visual field measurements were carried out 6months before (VFpre) and following (VFpost) successful cataract surgery. The difference between the mPD or mTD values in the VFpre and mTD values in the VFpost (denoted as epsilon mPD/mTD) was calculated, and the influence of the extent of true' glaucomatous visual field damage or cataract (as represented by epsilon mPD and mTD, respectively) on this difference was also investigated.Results There was a significant difference between mTD in the VFpre and mTD in the VFpost (p
