Popis: | AIM: To investigate the prevalence of and risk factors for lens opacities in populations living at two different altitudes in China. METHODS: A total of 813 subjects aged ≥40y in Lhasa (Tibet Autonomous Region, China. Altitude: 3658 m) and Shaoxing (Zhejiang Province, China. Altitude: 15 m) were underwent eye examinations and interviewed in this cross-sectional study. Participants’ lens opacities were graded according to the Lens Opacities Classification System II (LOCS II) and the types of opacities with LOCS II scores ≥2 were determined. Univariate and stepwise logistic regression were used to evaluate the associations of independent risk factors with lens opacities. RESULTS: Lens opacities were significantly more prevalent in the high-altitude than in the low-altitude area (χ2=10.54, P |
