Prevalence and associated factors for pterygium in rural agrarian central India. The central India eye and medical study.

摘要: PURPOSE: To evaluate the prevalence of pterygia and associated factors in a rural population mostly undeveloped agrarian region. METHODS: The Central India Eye Medical Study is population-based study performed region India. comprised 4711 subjects (aged 30+ years). A detailed ophthalmic medical examination was performed. pterygium diagnosed during slit lamp confirmed on corneal photographs. It defined as fleshy fibrovascular growth, crossing limbus typically seen nasal, sometimes temporal, conjunctiva. RESULTS: detected 798 eyes (prevalence rate: 8.47 ± 0.29%) 608 (12.91 0.49%) subjects. Bilateral were present 190 (4.0% population). Pterygia increased from 6.7 0.8% age group 30-39 years, to 13.5 1.2% 50-59 25.3 2.1% 70-79 years. Prevalence with older (P<0.001; regression coefficient B: 0.02; odds ratio (OR): 1.02; 95%CI: 1.01, 1.03), male gender (P<0.001;B:-0.73;OR: .48;95%CI:0.39,0.61), lower level education (P<0.001;B:-0.30;OR:0.74;95%CI:0.69,0.80), body height (P=0.001;B:-0.02;OR:0.98;95%CI:0.97,0.99), higher cylindrical refractive error (P<0.001;B:0.23;OR:1.26;95%CI:1.18,1.34). If dropped, number hours spent vigorous activity outdoors (P=0.001;B:0.001;OR:1.001;95%CI:1.000,1.0001) significantly pterygia, addition (P<0.001;B:0.03;OR:1.03;95%CI:1.03,1.04), (P<0.001;B:-0.49;OR:0.62;95%CI:0.49,0.77), (P=0.005;B:-0.02;OR:0.98;95%CI:0.97,0.99), (P<0.001;B:0.23;OR:1.25;95%CI:1.18,1.34). CONCLUSIONS: Pterygium about 13% among adult Indians aged Older age, gender, educational level, more time work factors. Since living conditions location untouched by modern developments, results may show associations without major or technologic influences.
