摘　　要：极低视力是量化评估视功能严重损害的重要参数,通常是指低于常规视力表检查范围内视力,科研统计中无法准确将极低视力转换成LogMAR值。国内学者通过5分计数法、标准对数视力表转换等方法研究极低视力的LogMAR值;国外学者通过计算机显示器、卡片等多种形式探索极低视力对应的LogMAR数值。本文给极低视力赋予定义并介绍研究意义。综述国内外学者对于极低视力转换成LogMAR值的研究,为医学统计研究提供参考。Extremely low vision is an important parameter to quantitatively evaluate the serious damage of visual function.It usually refers to the vision below the scope of routine visual acuity examination.In scientific research statistics,it is impossible to accurately convert extremely low vision into standard LogMAR values.Domestic scholars studied the LogMAR value of extremely low vision by means of 5-point counting method and standard logarithmic visual acuity chart conversion.Foreign scholars have explored the LogMAR value corresponding to extremely low vision through various forms such as computer monitors and cards.This article gived the definition of extremely low vision and introduces the significance of the study.This paper reviewed the research of domestic and foreign scholars on the conversion of extremely low vision into LogMAR values,and summarized the researches of domestic and foreign scholars on the conversion of extremely low vision to LogMAR values,to provide a reference for medical statistical research.
