The point of this study is to determine the age- and sex-specific prevalence and causes of visual impairment and blindness in adult Chinese Americans and to compare the prevalence to other racial/ethnic groups.
Exactly 4,582 Chinese American adults who were all 50 years and older underwent complete ophthalmologic examinations, including measurement of presenting and best-corrected visual acuity.
The prevalence of vision impairment and blindness was higher in older Chinese Americans compared with younger.
The primary causes of vision impairment were cataracts and myopic retinopathy; the primary cause of blindness was myopic retinopathy.
