对新的WHO视力损害分类标准的探讨

Discussion on the new WHO classification of visual impairment

2003年WHO在日内瓦召开了《视力损害及视功能特征标准进展的咨询会》,制定了新的盲及低视力分类标准。与现行WHO的盲及低视力分类标准相比,新的标准的特点是将视力损害分为轻度、中度、重度三类,而盲的视力标准不变。现行的视力标准为矫正视力,新标准为日常生活视力,而后者更符合日常实际的生活情况。作者结合临床和实践情况对新标准提出建议,认为将新的与现行的盲及低视力分类标准相结合,才能更好地解决防盲治盲的问题。

A consultation on development of standards for characterization of vision loss and visual functioning was held at WHO headquarters in Geneva from September 4 to 5,2003,and modified the existing classification of vision loss and blindness.The new WHO classification has 3 categories for vision loss,they are mild visual impairment,moderate visual impairment and severe visual impaiment,but blindness is the same to the current existing classification.The other difference is visual acuity.In existing classification,it is corrected visual acuity,and the new one is presenting distance visual acuity,We give some suggestions on the new classification based on our experiences in the clinical practice,that is to combine existing classification with the new one,and that will benefit the prevention and treatment of blindness.
