摘要
目的 :探讨北京盲校相隔 11年盲因及残余视力的变化。为防治儿童盲提出依据 ,并对我国盲校盲童及低视力分班教学可行性进行评估。方法 :应用眼科常规检查方法对北京盲校学生进行全面的眼科检查 ,全部视力检查结果均为矫正视力。并对 1989年及 2 0 0 0年两次调查结果进行比较与评估。结果 :在病因方面 ,1989年与本次 2 0 0 0年调查结果显示 ,先天性 /遗传因素均为主要致病因素 ,分别占总例数的 75 19%及73 91%。但主要致病因素在 1989年为先天性白内障 ,到 2 0 0 0年降至第三位。可治盲由 1989年的 2 7 91%降至 2 0 0 0年的0 87% ,可利用残余视力 ,1989年占总例数的 61 2 4% ,2 0 0 0年占 5 3 91% ,2 0 0 0年调查中 ,全部先无性青光眼均为术后病例 ,视力为光感及无光感者占 76 47% ;全部白内障术后无晶体中 ,视力为光感及无光感者占 2 3 0 8%。结论 :1989年第一位致病因素先天性白内障变为 2 0 0 0年的第三位病因先天性白内障 /无晶体 ,说明近年来白内障手术较前更为普及。可治盲由 1989年的 2 7 91%下降到 2 0 0 0年的 0 87% ,说明近年对患儿的眼科服务明显忧于以往。但先天性青光术后及白内障术后无晶体无有用视力者 ,分别为 76 47%及 2 3 0 8% ,说明提高以上两种常见儿童致盲眼的手术成功率 ,?
To study the changes in the causes and residual vision among eleven years in Beijing Blind School. Methods:The routine examinations of ophthalmology to check the students in details were used.The best correction of vision was recorded. Results:The causes of blindness were similar among 1989 and 2000.Congenital/hereditary factors were the main causes of blindness,in 1989 at the first position on the order of cause of blindness,and in 2000 at the third.The curable blindness was 27 90% in 1989,which reduced to 0 87% in 2000.61 24% of the students had the usable vision in 1989,and of 53 91% in 2000.All of the students with congenital glaucoma were post operation cases in 2000,in whom.74 47% had light or no light reception.In 23 08% of students with aphakia due to cataract surgery had the light or no light perception of vision. Conclusions:The first cause of blindness was congenital cataract in 1989,and it became the third in 2000.The curable blindness from 1989 to 2000 was reduced from 27 42% to 0 87%.However,76 47% and 23 08% patients with congenital glaucoma and aphakia had no usable vision,which indicated that the successful operation especially for congenital glaucoma is the most important for the prevention of childhood blindness.More than 50% students who had usable vision in Beijing School for the Blind in 1989 and 2000,it is quite evident that low vision education is still great importance to the blind schools in China.
