Purpose. Demonstrate that geographic altitude is a factor associated to Pterygium development. Methods. A cross-sectional study carried out in the villages of Trujillo (sea level) and Huamachuco (3169 masl), through a screening campaign conducted in 514 people in Trujillo and in 158 settlers in Huamachuco, with prior informed consent. A non invasive ocular evaluation with a portable slit lamp was performed, looking for the presence of pathology, the affected eye, the affected eye pole and the grade of Pterygium. We supplement the information with questions about demographic variables (age, sex, marital status, occupation, exposure to dust, urban or rural residence, consumption of alcoholic beverages and tobacco, instruction level and family history of Pterygium) by 10 direct questions. The information was processed with the IBM SPSS Statistics 23 software, performing an univariate, bivariate and multivariate analysis, considering IC 95% and p<0.05. Results. The overall prevalence of the Pterygium is 15.8% (27.8% at ≥ 3000masl). The bivariate analysis shows as factors associated with Pterygium development the geographic altitude ≥ 3000masl (OR: 2.460, p <0.001, 95% CI [1.70-3.54]), age ≥ 65 years, residence in rural regions, outdoor work, exposure to dust, smoking and family history of Pterygium. The multivariate analysis identified as independent associated factors age ≥ 65 years, residence in rural region and family history of Pterygium. Conclusions. Pterygium is a public health problem. The altitude ≥ 3000msnm increases the risk of developing in 2.46 times; however, it is not an independent associated factor.
