Relationship between Myopia and Optical Components - A Study among Chinese Hong Kong Student Population

Purpose: To establish the prevalence and severity of myopia among the Chinese Hong Kong students and to study the relationship between myopia and optical components. Methods: One thousand and seventy-five freshmen of the 1993-1994 academic year in the Chinese University of Hong Kong underwent the eye examination including evaluation of refractive error, keratometry, and A-scan ultrasonic biometry. The data were analyzed with the SPSS/PC + 4. 01 statistical package. Results: The prevalence of myopia was 91.7% with the mean refraction being -4.00 ± 2.64D in this young adult population. The statistical analyses demonstrated a significant correlation between refractive value and axial length of the globe (r=-0.78), vitreous length (r=-0.76), anterior chamber depth (r=-0.33), lens thickness (r = 0.13) and corneal curvature (r = 0.19). Conclusion-. The refractive status is mainly dependent on the axial length. In general, the higher the myopia was, the longer the eyeball, the deeper the anterior chamber, the steeper the cornea, and the thinner the lens would be.
