Abstract

The World Health Organization (WHO) estimates, worldwide, approximately 1300 million people with a form of visual impairment. More than 314 million have a severe visual impairment. Of these, 37 million are blind and 124 million suffer from low vision. Eighty percent of all these cases are considered avoidable. The main causes of blindness from one country to another, in order of frequency, are cataract (39%), uncorrected refractive errors (18%), and glaucoma (10%). In Latin America and the Caribbean, the loss of vision in adults continues to be a public health problem. Blindness and visual impairment tombs have a remarkable impact on the socioeconomic development of individuals and societies and the prevention of avoidable visual disabilities in the long term in terms of attention to health care and social expenditures. Of all the organs of the body, the eye is more accessible to direct examination. The visual function can be evaluated by means of simple subjective tests. The same can be taken care of from an adequate primary care service.
视力障碍和可预防失明的原因
世界卫生组织(世卫组织)估计,全世界约有13亿人患有某种形式的视力障碍。超过3.14亿人有严重的视力障碍。其中,3700万人失明,1.24亿人患有低视力。80%的病例被认为是可以避免的。各国致盲的主要原因(按发生频率排列)分别是白内障(39%)、未矫正屈光不正(18%)和青光眼(10%)。在拉丁美洲和加勒比,成人视力丧失仍然是一个公共卫生问题。失明和视力障碍对个人和社会的社会经济发展以及可避免的视力障碍的预防具有显著的长期影响,包括对卫生保健的关注和社会支出。在身体的所有器官中,眼睛是最容易直接检查的。视觉功能可以通过简单的主观测试来评估。同样可以通过适当的初级保健服务得到照顾。
