Purpose:
A retrospective study was developed to evaluate risk factors in adult-onset myopia.
Methods:
Subjects included were 25 to 35 years old. There were 116 non-myopic subjects in the control group and 66 myopic subjects with first lens prescription at age 17 or later. Subjects received a questionnaire about academic achievement, daily hours of reading during years of study, and family history of myopia.
Results:
The level of academic achievement was similar for myopic and non-myopic groups in this sample. Myopia was associated with family history (chi(2) = 6.131, p
Conclusions:
After multivariate analysis, adult-onset myopia was significantly associated only with family history of myopia.
