高龄老年人472眼屈光状态的临床分析

目的:探讨高龄老年人眼视力状况及屈光分布,做好高龄老年人的视力保健。方法:标准照明下查70岁以上高龄老年人472眼远视力,作仔细的眼部和屈光状态的检查并矫正其视力。结果:全组472眼中屈光不正468眼(99.2%),全组以近视居多,且随着年龄递增,近视所占比例逐渐增大。散光415眼(87.9%),70～80岁组以远视散光为主,80岁以上则以近视散光为主,全组散光以近视性逆规散光眼所占比例最大,共172眼(36.4%),远视散光眼散光度数集中在0.50～1.00D,近视散光和混合性散光眼度数集中在1.25～2.00D。全组裸眼视力随年龄增加而降低,各年龄组矫正视力均有明显提高。结论:高龄老年人由于眼睑和晶状体等的老年性改变,其屈光状态向近视性逆规散光发展,成为影响其视力的主要原因,尚未行白内障摘除之高龄老年人,定期检查其屈光状态并做必要的屈光矫正能明显提高高龄老年人的视力。

Clinical analysis on the refractive condition of 472 eyes in elderly people over 70 years of age

AIM:To evaluate the visual acuity and refractive condition of some elderly people over 70 years of age.·METHODS:An examination was done under standard lighting for the distance visual activity and a complete ocular examination was performed in 472 eyes.Then refractive condition was examined and the vision was checked.·RESULTS:There were 468 ametropic eyes in the whole group(99.2%).Most of them were myopia and the proportion of myopia increased with age.There were 415 (87.9%)astigmatism eyes and there were a total of 172(36.4%) myopic astigmatism eyes which had the largest proportion of the whole group.Hyperopia astigmatism were more in the 70-80 age group while myopic astigmatism while more over 80 years old.The degree of the hyperopia astigmatism eye were mainly between 0.50D to 1.00D when it was mainly between 1.25D to 2.00D in the myopic astigmatism eyes.The rectification of vision in various age had a satisfactory improvement.·CONCLUSION:Because of the age-related changes of eyelid and cataract the eyes have a trend to be myopic astigmatism,which is the most common cause that affects the vision of the elderly people.Regular check on the condition of refraction of the eyes of aged people should be one part of the regular examination and refractive error correction can improve the quality of daily life for elderly people.
