The Current Status Of Vision Disability In Beijing And The Evaluation Of Visual Aids

SignificanceThe major disability factors of vision disability is great changed in proportionand quantity with the development of society in China. The epidemiological featuresof vision disability is not only the basis of formulating correlated policy bygovernment department but also the important precondition of effectively control ofvision disability. It is gradually improved both the recognition to vision disability andvisual aids and the national assistance in recent years. The demand is a importantsubject to Disabled Persons’ Federation that offer more standard, high quality,efficient and personalized rehabilitation service to vision disability.AimThe study investigated the basic situation, grade distribution and the majordisability factors of the peoples who identified of vision disability in Beijing city orsuburbs in2012.It investigated and analysised on the epidemiological features ofvision disability and the major disability factors of vision disability as well as theusing condition of visual aids and the difference of the rehabilitation effect in thepatients with visual disability. The results can provide evidence for effectively controlof vision disability and the rehabilitation.MethodThere were two parts of the study.1.Investigation of the patients with visual disability in Beijing. The study investigatedthe patients with visual disability in Beijing in2012.The personal information and thecause of visual disability were detailed record.They were graded according to thesecond national disabled sampling survey of vision disability classification standard.2.Evaluation of visual aids rehabilitation effect in visual disability patients. Thedifference of reading success rate was compared among the patients using differentvisual aids. It compaed of the rehabilitation effect before and after using visual aids byusing the rank sum test. The removing residual rate and reading success ratedifferences were compared by using chi-square test. Results1.The study was accorded to the statistical basic situation of visual disability patientsregistered in the Beijing deformity certificate management system in2012.(1)There are44159holders of visual disability certificate in Beijing,inciuding52.85%males and47.15%females. The middle and old age patients who more than41years old is88.84%of all visual disability patients.(2)The first three disability reasons were etinal and uveitis lesions, congenitalabnormalities or developmental disorders and cataract.Their percentage in totalvisual disability were16.33%、1,6%and10%.(3)Grade1to Grade4of visual disability in Beijing were respectively23.87%,15.61%,13.42%and47.10%.(4)The number was8.66%of total visual disability patients who got the povertysubsidy.The highest proportion is12.80%in the outer districts and counties.2.Evaluation of common visual aids rehabilitation effect(1)Distance vision was improved in both low vision group and blind group after usingsingle tube telescope and long distance glasses type devices.(2)The difference from visual handicap was no significant betwent low vision groupand blind group after using single cylinder hand-held telescope and distance glassestype telescope.(3)Reading success rate in two groups using electronic visual aids was higher than itusing near glasses type visual aids(χ�'=9.45，P=0.0021)、(χ�'=30.24P<0.0001)Conclusion1. The epidemiological features of visual disability.(1) The ratio of blindness increased with male gender(2) The middle and old age patients who more than41years old is88%of allvisual disability patients.(3))The first three disability reasons were etinal and uveitis lesions, congenitalabnormalities or developmental disorders and cataract.Their percentage in totalvisual disability were16.33%、1,6%and10%.(4) Grade1to Grade4of visual disability in Beijing were respectively23.87%,15.61%,13.42%and47.10%.(5) The number was8.66%of total visual disability patients who got the povertysubsidy.The highest proportion is12.80%in the outer districts and counties. 2.Visual aids can effectively improve the vision of visual disability.(1) Distance vision was improved in both low vision group and blind group afterusing single tube telescope and long distance glasses type devices.(2) The difference from visual handicap was no significant betwent low visiongroup and blind group after using single cylinder hand-held telescope and distanceglasses type telescope.(3).Reading success rate in group using electronic visual aids is better than thatusing optical visual aids.This study described and analyzed the basic vision disability information ofBeijing. The rehabilitative effects of frequently-used visual aids were comparedand the current existing problems and shortcomings in visual aids services wereanalyzed. Then several corresponding countermeasures and suggestions aboutfuture work were presented as following:（1）Improving the visual aids policy and increase the power on allowance ofvisual aids;（2）Further strengthening the institute construction and building the servicenetwork of visual aids;（3）Accelerating cultivation of talents, advancing assessment and adaptationservices;（4）Strengthening the study and communication for visual aids;（5）Integrating the work on visual aids into the overall work with disabilities.
