方法：对96例109眼慢性闭角型青光眼患者应用眼科电生理仪、视野、眼底照相和OCT，根据P-VEP、视野、眼底照相和OCT检查结果的阳性率进行相关性分析。

结果：选取96例109眼获得P-VEP阳性病例72眼(66.1%)，未见明显异常37眼(33.9%)； 视野检查显示阳性病例84眼(77.1%)，未见明显异常25眼(22.9%)； 眼底照相成功获取阳性病例图像87眼(79.8%)，未见明显异常22眼(20.2%)； 成功获取OCT阳性病例图像94眼(86.2%)，未见明显异常OCT图像15眼(13.8%)。OCT阳性检出率高于视野检查、眼底照相、P-VEP检查(P<0.05)。OCT在获取前房角图像与三面镜检查相比无统计学差异(P>0.05)。

结论：视觉电生理检查、视野、眼底照相和光学相干断层图像结果对慢性闭角型青光眼患者的视功能状况进行综合评估。

METHODS:Visual electrophysiological examination, fundus photography, visual field and OCT were used to evaluate the chronic angle-closure glaucoma in 96 cases(109 eyes). The correlations were analyzed according to the results of P-VEP, fundus photography, visual field and OCT.

RESULTS:In 96 cases(109 eyes), P-VEP was positive in 72 eyes(66.1%). The P-VEP was no obvious abnormal in 37 eyes(33.9%). Visual field inspection successfully acquired positive cases images in 84 eyes(77.1%), no obvious abnormal in 25 eyes(22.9%). Fundus photography captured positive cases in 87 eyes(79.8%), no obvious abnormal in 22 eyes(20.2%). OCT image captured positive cases in 94 eyes(86.2%), no obvious abnormal in 15 eyes(13.8%). The positive rate of OCT was higher than that of visual field examination, fundus photography, P-VEP examination(P<0.05). The capability of obtaining anterior chamber image by OCT and the three-mirror examination showed no significant difference(P>0.05).

CONCLUSION:Visual electrophysiological examination, visual field, fundus photography and OCT can evaluate the visual function in patients with chronic angle-closure glaucoma for comprehensive assessment.
