Abstract:AIM:To study the reliability of visual electrophysiological examination(pattern visual evoked potentials, P-VEP), fundus photography, visual field and optical coherence tomography(OCT)to evaluating chronic angle-closure glaucoma.
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.
