因不同的眼部和神经性疾病，导致视觉功能严重受损，为低视力患者日常活动(如阅读及驾驶)及生活质量、心理健康带来严重的影响。人们对外界信息的感知主要来源于视觉，除威胁生命的重大疾病外，对人感官影响最大的损害当属视觉损伤。且随着人口日益老龄化，该问题日趋加重，低视力已成为目前全球范围内一个严重的公共卫生问题。目前，低视力康复发展面临着临床和科研的巨大挑战，要研发出一种能有效改善视觉功能，同时能兼顾多种功能的视障辅助技术，这需要医学、生物学、工程学、微电子学、计算机学等多学科的共同发展和相互合作。低视力康复通过为患者提供适宜的视障辅助技术，最大化利用患者的残余视力及视觉功能，改善与低视力相关的功能限制，有效改善其独立性和整体生活质量，使其独立生活、工作并融入社会成为可能。该文对经典的助视器、人工视觉(视觉假体/视觉感官替代设备)、经颅刺激及视觉生物反馈训练等视障辅助技术在低视力康复中的应用进展进行综述。

Patients with low vision are severely impaired in visual function due to different ocular and neurological disorders,which have a serious impact on their daily activities (such as reading and driving), quality of life and mental health.People's perception of external information mainly comes from vision. Expect for the life-threatening major diseases,visual damage has the greatest impact on people's senses. With the ageing of the population, the problem is getting worse, and low vision has become a serious public health problem in the world. Currently the development of low vision rehabilitation is facing a huge challenge in clinical and scientific research, to develop a visual impairment assistance technology that can effectively improve visual function while balancing multiple functions. It requires the joint development and cooperation of multiple disciplines such as medicine, biology, engineering, microelectronics, and computer science. Low vision rehabilitation provides patients with appropriate visual impairment assistance technology,maximizing the use of residual vision and visual function of patients, improving the functional limitations associated with low vision, effectively improving their independence and overall quality of life, and makes it possible for them to live, work and integrate into the society independently. This article reviews the progress in the application on visual impaired assistive technologies such as classic visual aids, artificial vision (visual prostheses/visual sensory replacement devices), transcranial stimulation and visual biofeedback training in low vision rehabilitation.

目的：调查引导式教育训练对视力障碍学生生活质量的影响。方法：前瞻性随机对照临床研究。选取2020年在泉州特殊教育学校就读视力障碍学生，按照入组条件随机分为引导式教育训练组和对照组，引导式教育训练组进行引导式教育训练，对照组进行常规康复训练。采用中文版低视力者生活质量量表(Chinese-version low vision quality of life questionnaire，CLVQOL)评估视力障碍学生的基线和训练3个月的生活质量，并进行比较分析。结果：72例视力障碍学生全部完成了基线和随访时的生活质量问卷调查。进行基线检查时，各组CLVQOL评分总分差异无统计学意义(P>0.05)。3个月后，各组CLVQOL评分总分均增加，引导式教育训练组从基线59(48.5，80.5)上升到105(97.5，119.5)，差异有统计学意义(Z=?4.781，P<0.001)；对照组从基线69(56，85)上升到106(80，112)，差异有统计学意义(Z=?4.438，P<0.001)；引导式教育训练组在CLVQOL评分总分(P=0.021)及阅读和精细工作维度(P=0.004)、日常生活能力维度(P=0.003)的评分差值均高于对照组。结论：引导式教育训练是一种重要的低视力康复训练方法，可以明显提高患者的生活质量。

Objective: To investigate the effect of conductive education training on the quality of life in visually impaired students. Methods: It was a prospective randomized controlled trial. The visual impairment students who had registered in Quanzhou Special Education School in 2020 were selected and randomly divided into two groups: conductive education training group and control group. The conductive education training group received conductive education training, while the control group received routine rehabilitation training. Chinese version low vision quality of life questionnaire (CLVQOL) was used to assess the quality of life of low vision students at baseline and 3 months after training, and comparative analysis was conducted. Results: All 72 students with visual impairment completed CLVQOL surveys. At baseline, there was no significant difference in total CLVQOL scores between groups. After 3 months, overall CLVQOL scores increased in both groups, from baseline 59 (48.5, 80.5) to 105 (97.5, 119.5) in the conductive education group (Z=-4.781, P<0.001), and 69 (56, 85) to 106 (80, 112) in the control group (Z=-4.438, P<0.001). The total score of CLVQOL (P=0.021), reading and fine work subscale (P=0.004), and daily activities subscale (P<0.003) in the conductive education training group were higher than those in the control group. Conclusion: Conductive education training is an important method of low vision rehabilitation training, which can significantly improve the quality of life of patients.

目的：对儿童癔症性视力障碍的病因进行分析，比较试镜与人工泪液给药治疗的疗效。方法：纳入2013年10月至2020年10月以“癔症性突发视力下降”于深圳市儿童医院门诊就诊的36例患儿，其中男16例，女20例。按随机原则分为试镜组与人工泪液给药组。两组在治疗过程中都辅以语言暗示。两组治疗的首次有效率采用SPSS17.0软件Fisher精确概率检验。分析儿童癔症性视力障碍的发病原因，提出诊断要点和防治对策。结果：在辅以语言暗示的前提下，试镜组人工泪液给药组治疗方案的首次有效率分别为94.4%、83.3%，差异有统计学意义(P<0.05)。在相关病因分析中，学习压力相关的有20例，占55.6%，包括成绩下降、逃避考试、因成绩受到家长或老师的训斥，甚至体罚。家庭变故13例，占36.1%，父母离异为主要原因。留守儿童不愿返乡、同学纠纷、校园霸凌以及外伤等为其他原因。结论：试镜加语言暗示比人工泪液加语言暗示更能有效提高癔症性视力障碍的首次治疗有效率。学习压力、家庭变故相关因素为癔症性视力障碍的最常见原因

Objective: To analyze the causes of hysterical visual impairment in children, and to compare the efficacy of two treatments of trial frame and artificial tears administration. Methods: A total of 36 children with sudden hysterical visual impairment admitted to Shenzhen Children’s Hospital from October 2013 to October 2020 were enrolled in our study, including 16 males and 20 females. They were randomly divided into trial frame group and artificial tears group. Both groups were supplemented with verbal suggestion during the treatment. The primary effective rates of the two groups were compared by SPSS 17.0 Fisher’s exact test. The causes of hysterical visual impairment in children were analyzed, and the main points of specific diagnostic tests and treatments were summarized. Results: The primary effective rate of the trial frame group and the artificial tears group were 94.4% and 83.3% respectively.Thedifference was statistically significant (P<0.05). In this study, therewere 20 cases (55.6%) related to study pressure, including decline in academic performance, evasion of exams, reprimand by parents or teachers, and even corporal punishment. There were 13 cases (36.1%) caused by family accidents, and parents’ divorce was the main reason. Leftover children unwilling to return hometown, classmate disputes, campus bullying and trauma were other reasons. Conclusion: Trialframe is more effective than artificial tears therapy in improving primary effective rate of hysterical visual impairment. Study pressure, family accident are the most common causes of hysterical visual impairment
