    Abstract:

    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.
