The progression of myopia has been a topic of many previous studies. One such study, by Dennehy and Heetland was designed to track and analyze myopic progression in the pre-presbyopic adult years and compare differences between two different categories: the first being general population 20-30 age range vs. general population 30-40 age range, and the second male vs. females. Dennehy and Heetland found the progression of myopia is not statistically significant to the 0.05 level in both cases even though there was a significant increase in myopia. The current study is a follow up to the Dennehy and Heetland study and is a retrospective study that used 49 records from clinics in the Portland metro area affiliated with the Pacific University College of Optometry.
