Abstract：Objective To explore the effects of virtual reality(VR)technology-based brain visual training on visual function defects and visual quality in glaucoma patients.Methods A total of 98 glaucoma patients treated in 363 Hospital from March 2021 to February 2023 were selected and divided into observation group and control group according to random number table method,with 49 cases in each group.The control group was given routine visual function training,and the observation group was given VR technology-based brain visual training on the basis of the control group.Both groups were continuously trained for 3 months.The visual acuity,intraocular pressure,visual function defects,retinal nerve fiber layer(RNFL)thickness,optic disc volume(DV),National Eye Institute Visual Functioning Questionnaire-25(NEI VFQ-25)score,Glaucoma Quality of Life-15(GQL-15)score were compared between the two groups.Results After 1 month and 3 months of training,the visual acuity,RNFL thickness,DV and NEI VFQ-25 scores in the observation group were higher than those in the control group,while the intraocular pressure and GQL-15 scores in the observation group were lower than those in the control group,and the differences were statistically significant(P＜0.05).Before training and 1 month after training,there were no statistically significant differences in the defect rates of inhibition,perceptual eye position,stereoscopic vision,fixation stability and visual noise between the two groups(P＞0.05).After 3 months of training,the defect rates of inhibition,perceptual eye position,stereoscopic vision,fixation stability and visual noise in the observation group were significantly lower than those in the control group(P＜0.05).Conclusion VR technology-based brain visual training can improve the visual acuity,visual function,RNFL thickness and DV of glaucoma patients,and reduce their intraocular pressure,and improve their visual quality and quality of life.
