Introduction: In Lima with a population of almost three million children it has been not reported until now child allergy prevalence studies. Objectives: To determine the current epidemiological characteristics of childrens eye allergy in the poor elementary students in South of Lima. We took significant sample to students from 8 primary schools in three districts in the South of Lima, with 120,000 children. Material and method: A cross-sectional and observational study was made, assessed and considered, on-site at each school 2,011 elementary students. For the calculation of samples we use Excel 2003 and for analysis we use SPSS 15.0. Results: With an increase in the frequency of eye allergy that increases with age. Eye allergy is more correlated with the blepharitis and the chalazion. Conclusions: The prevalence of eye allergy 16.3% is moderate in the primary...

Background: There are almost 12 million children in Peru, and no studies regarding the prevalence of ametropia or amblyopia in school children have ever been reported.Objetives: To determine the epidemiologic characteristics and current therapy strategies for severe ametropia and amblyopia in students from limited-resource families in Southern Lima, Peru.Material and methods: A significant sample representative of 120,000 children from 42 schools in five districts of Southern Lima was assessed. The study was performed in three stages. The first one was a cross-sectional and observational survey, assessing visual acuity and performing refraction testing in 12,364 students. The second stage consisted in follow-up assessments in students with moderate and severe ametropy, aiming to confirm their ametropy degree and its respective cyclopegic refraction. The third stage detecte...
