To explore whether individualized visual training improves the visual acuity and visual field defects of patients with glaucoma. Patients with established primary glaucoma who visited the glaucoma clinic of Beijing Shijitan Hospital, Capital Medical University from January 2018 to April 2018 were recruited. The binocular visual perception examination was performed by using the visual perception examination system, and a personalized training program was developed according to the relevant threshold conditions between the eyes of the patients. The binocular visual perception training session for 20 minutes for two sessions was completed at home by using a virtual reality helmet. The visual function, intraocular pressure, and Octopus visual field were examined, before and at the first month and the third month after training. Seven patients completed the study. None of the seven patients has fine stereopsis, four of them have large stereopsis, and two patients are without large stereopsis. The visual acuity at 3 months after training was significantly improved compared with that before training. The mean defect value after 1 month of training was significantly lower than that before training, and it was further decreased after 3 months. Similarly, the mean sensitivity value was significantly increased in both follow-ups after training. There was no significant difference in loss variance after 1 and 3 months of training when compared with that before training ( > 0.05). Our small prospective observational study indicated that individualized visual perception training can improve the visual function and improve the visual field in patients with glaucoma, and a large sample size study is warranted to further assess the value of this novel treatment.
为了探索个体化视觉训练是否能改善青光眼患者的视力和视野缺陷。2018 年 1 月至 4 月期间，我们在北京世纪坛医院首都医科大学附属眼科中心招募了已确诊的原发性青光眼患者。使用视觉感知检查系统对双眼视觉感知进行检查，并根据患者双眼之间的相关阈值条件制定个性化的训练计划。患者在家中使用虚拟现实头盔完成 20 分钟的 2 次双眼视觉感知训练。在训练前、训练后的第 1 个月和第 3 个月检查视觉功能、眼压和 Octopus 视野。7 名患者完成了研究。这 7 名患者均无精细立体视觉，4 名患者有大立体视觉，2 名患者无大立体视觉。与训练前相比，训练后 3 个月视力明显提高。训练后 1 个月的平均缺损值明显低于训练前，3 个月后进一步降低。同样，在训练后的两次随访中，平均敏感度值均显著升高。与训练前相比，训练后 1 个月和 3 个月的损失方差无显著差异（>0.05）。我们的小型前瞻性观察研究表明，个体化视觉感知训练可以改善青光眼患者的视觉功能和改善视野，需要更大的样本量研究来进一步评估这种新疗法的价值。
