BACKGROUND
To define age-related changes in the visual field by comparing 'standard' central and unique peripheral visual field measurements in healthy volunteers.
METHODS
In a single center, retrospective, Cross-sectional, observational study, 20 volunteers with no retinal diseases or risk factors, ranging in age between 30 and 94 years (four age groups: 30's, 50's, 70's, 90's) were measured in one eye (preferentially the right one) using a Humphrey visual field 24-2 and 60-4.
RESULTS
While the central visual field remained relatively well preserved during aging showing only a mild reduction in sensitivity, a profound loss of the peripheral visual field was observed beginning in the fifth decade of life and decreasing continuously up to the 90ies.
CONCLUSIONS
The peripheral visual field declined substantially from the 4th decade onward while the central visual field remained quite stable.
背景
通过比较健康志愿者“标准”的中央和独特的周边视野测量结果来定义与年龄相关的视野变化。
方法
在一项单中心、回顾性、横断面观察性研究中，对20名无视网膜疾病或风险因素、年龄在30至94岁之间（四个年龄组：30多岁、50多岁、70多岁、90多岁）的志愿者的一只眼睛（优先选择右眼）使用Humphrey视野24-2和60-4进行测量。
结果
虽然中央视野在衰老过程中相对保持良好，仅显示出敏感性略有下降，但从生命的第五个十年开始观察到周边视野严重丧失，并持续下降直至90多岁。
结论
从第四个十年起周边视野大幅下降，而中央视野保持相当稳定。
