目的:比较轻、中、重度近视患儿之间的视觉功能的差异,探索虚拟现实下的短期可塑训练对近视视觉功能的改善效果。方法:选择2022年6月—2022年9月就诊于苏州大学附属儿童医院的6~16岁儿童102例,按照屈光度分为正常对照组、轻度近视组和中重度近视组,进行眼科常规检查和视知觉功能检查,并进行视觉短期可塑训练。结果:近视患儿存在立体视功能缺损,近视程度与精细立体视功能损害呈正相关,各组之间比较差异具有统计学意义(P<0.05),部分患儿存在中心凹抑制。训练后,轻度近视组的中距离精细立体视功能得到改善,比较差异具有统计学意义(P<0.05)。结论:近视患儿存在立体视功能异常和中心凹抑制,且立体视功能的损害随着近视程度的增加而加重。轻度近视患儿部分精细立体视功能经过虚拟现实短期可塑训练可得到改善,而中重度近视患儿精细立体视功能改善不明显。
Objective: To compare the difference of visual function among children with myopia in different diopter, and explore the effect of short-term plastic training of virtual reality on visual function improvement. Methods: The 102 children aged 6-16 years who admitted to Children's Hospital of SoochowUniversity from June 2022 to September 2022 were recruited and divided into control group, mild myopia group and middle and high myopia group according to diopter. Routine ophthalmologic examination and visual perception function examination were carried out, and short-term plastic training was implemented. After the training, visual perception function examination was completed again. Results: There were significant differences in stereoscopic function defect at different distances among myopic children, a negative correlation between myopia and stereoscopic function was found. while there were several cases have foveal suppression. After training, the fine stereopsis at medium distance of the mild myopia group was significantly improved with significance statistical difference. Conclusions: Myopia can lead to the abnormality of stereopsis and foveal suppression in children. The defect of binocular visual function increases with the increase of myopia. Short term plastic training of virtual reality can partially improve the fine stereoscopic function of mild myopia children whileshowsnosigni ficanceimprovementof the fine stereoscopic function in middle and high myopia group.
青光眼是全世界范围内不容忽视的致盲性眼病,其起病隐匿,视功能损害进展迅速,晚期预后不理想。长期发展且未行治疗的青光眼患者视神经呈进行性损害,引起视力急剧下降、视野不可逆性缺损,严重降低患者的生活质量。为了适应逐渐恶化的视功能,患者注视行为发生明显变化,由此在日常活动中引起步态行为随之改变,意外事故频繁发生。故目前对于青光眼的研究引起国内外广泛重视,虚拟现实技术(virtual reality,VR)作为青光眼早期诊断及康复治疗的新手段已被现代医学所尝试。本文具体阐述了青光眼的视觉损害与注视行为及运动行为间的联系,并总结了目前国内外关于VR诊断青光眼及作为康复治疗的相关研究。
Glaucoma is a blinding eye disease that cannot be ignored worldwide. Its onset is insidious, visual impairment is progressing rapidly, and the late prognosis is not ideal. Long-term untreated glaucoma patients show progressive damage to the optic nerve, causing a sharp decline in vision, irreversible visual field defects, and severely reducing the quality of life of the patients. In order to adapt to the gradual deterioration of visual function, the patient’s gaze behavior changes significantly, which causes the gait behavior to change in daily activities, and accidents occur frequently. Therefore, the current research on glaucoma has attracted wide attention in the nation and abroad,and virtual reality (VR) technology has been tried in modern medicine as a new method for early diagnosis and rehabilitation of glaucoma. This article specifically elaborates the relationship between the visual impairment of glaucoma and the gaze behavior and movement behavior, and summarizes the current domestic and foreign research on the diagnosis of glaucoma and the rehabilitation of VR technology.
