[Abstract]:Objective to investigate the basic situation, grade distribution and main causes of visual disability identification in Tianjin during the 11th Five-Year Plan period, and to evaluate the rehabilitation effect of visual aids for some patients with visual disability with residual visual acuity. Methods this subject is divided into two parts. Part one: 15834 patients with visual disability were collected from January 2006 to December 2010 in Tianjin. According to the second National sample Survey of the disabled, the patients were classified and the causes of disability were determined. The differences of frequency distribution of blindness and low vision among different disability causes, age, sex, region, education level and family income were tested by x: test. Two-classification Logistic regression analysis was used to screen the related factors of visual disability. Part two: 283 patients aged 9-79 with partial visual impairment with residual vision were divided into blind and low vision groups according to the degree of visual disability. The visual acuity and dedisability rate before and after the use of single-tube hand-held telescopes and spectacle telescopes were compared, and the reading success rates of hand-held magnifying glasses with light source, near-use spectacle aids and electronic visual aids were compared respectively. The rehabilitation effect of far vision before and after using visual aids was matched t test, and the difference between two kinds of remote visual aids and the reading success rate of three kinds of low vision aids was analyzed by 蠂 2 test. Results (1) among 15834 patients with visual disability, male, urban area, higher age, lower education level and low family income accounted for a larger proportion (P0.001). 6598 (41.67%) of 15834 patients with visual disability were blind, among which 5015 (31.67%) were first-grade and 1583 (10.00%) second-grade; 9236 cases (58.33%) had low visual acuity, of which 1713 cases (10.82%) were third grade, 7523 cases (47.51%) were grade four, and 5196 cases (32.82%) were cataract. The primary cause of disability was blindness (32.98%) and low vision (32.70%). With the exception of cataract, the main causes of blindness and low vision were different (x 2o 38.3 P 0.001). The main causes of blindness were retina, uveal lesion (15.40%), keratopathy (13.78%), and low vision (18.32%). Uveal lesions (17.37%). 4. The far visual acuity of the blind group and the low vision group were improved after the use of hand-held telescope and spectacle telescope. The difference was statistically significant (P 0.05). 5. There was no significant difference between blind group and low vision group (P < 0. 823). There was no significant difference between blind group and low vision group (P < 0. 823, P < 0. 899). The reading success rate of the two groups was higher than that of the hand-held magnifying glass with light source and the near-use spectacle type low vision aid (x2o6.918), (x 17.145), (P0.01). Conclusion 1. The incidence of visual disability in Tianjin during the 11th Five-Year Plan period is related to many factors. Advanced age, urban area and low education level are the risk factors of blindness. 2. Cataract is still the leading cause of disability. We face great challenges and tasks in the prevention and treatment of low vision. The extensive development of rehabilitation of low vision is urgent. 3. Visual aids can help the patients with visual impairment make effective use of their residual visual acuity, and the effect of visual rehabilitation is remarkable. Publicity and popularization should be strengthened among patients with visual disability.
