ABSTRACT Objective To verify the prevalence and the main causes of low visual acuity among students, to correct refractive errors with eyewear, and to establish a relation between vision and school performance. Methods This is a cross-sectional, quantitative study of a social action carried out in a public elementary and high school in the city of Araçatuba (SP). Specialized evaluation was indicated to students who presented visual acuity ≤0.7 in one or both eyes, with or without prior optical correction, […]

Abstract Background: The visual screening performed in schools is sometimes the only opportunity to detect uncorrected refraction errors (URE) causing low visual impairments, prejudice in the acquisition of knowledge, dropout and school repetition, poor motor skills, difficulty in social interaction and low self-esteem in schoolchildren. Objectives: To compare the detection of URE in elementary school children by visual screening (measurement of the AV with the Snellen table) and photoscreening; to evaluate the accuracy of the SpotTM Vision Screener (Welch Allyn) […]

Objectives: To compare the aniseikonia and the stereopsis in school children anisometropes of the first-year of elementary school corrected with stock ophthalmic lenses with base curve selected to minimize the interocular size difference of retinal images and with size lenses suggested by the software Aniseikonia Inspector 3, and to check the preference of them for one of these forms of correction. Methods: Nineteen school children with anisometropia ≥ 1.5 D in corresponding meridians, in the use of glasses with stock […]

Objective: To evaluate the epidemiological profile of visual acuity (VA) dysfunction, the possible ocular disorders and the frequency of ophthalmologic care of school children from the city of Itaúna, Minas Gerais, Brazil. Methods: A cross-sectional study with a population of 432 students in the public schools. The individuals were evaluated by the Snellen method and the sample age ranged from 4 to 17 years. Data were collected and systematized. Those who had VA ≤ 0.7 in at least one eye […]

Objective: Measure the “Projeto Olhar Brasil” under a critic point of view, examining the prevalence of patients referred for ophthalmological appointment, post-screening, that show refractive errors uncorrected. Methods: Review of records between March 2014 and August 2016, in totality of 339 patients between 6 and 18 years old, 5 preschools (2 – 6 years and 11 months) 124 school (7 – 9 years and 11 months) and 210 teenagers (10 – 20 years old). There were 156 males and 183 […]

Objective: The purpose of this study was to promote the teaching of trachoma and to act in the combat of this leading cause of preventable blindness. Methods: This proposal was approved by the Ministry of Health (PET Program – Health/Health Surveillance), predicting the service training of medicine and nursing graduate students and health workers, in Botucatu, Sao Paulo – Brazil, in 2010. The training covered theory and practice, which consisted of cross-sectional study, with a randomized sampling to study the […]

Objective: To determine the prevalence of low vision in a fraction of the students in public schools at Caratinga, Minas Gerais. Moreover, show the relevance of preventive measuresto evaluate Visual Acuity (VA) in children up to 7 years old. Methods: A transversal study was made in students, between 4 and 7 years old, enrolled in first and second year of elementary school of Geraldo Marques Cevidanes Municipal School, in the city of Caratinga, Minas Gerais.VA was evaluated using Snellen optometric […]

OBJECTIVE: We intend to evaluate the prevalence of visual disorders among 8 to 10-year-old students from a public school in Pouso Alegre, state of Minas Gerais, as well as verify the possible legitimacy of the correlation between a poor school performance and some kind of visual deficit. METHODS: We conducted a transversal and quantitative study whose target were the students enrolled in the elementary course (2nd to 4th grade) of Pio XII Municipal School in the academic year of 2009.
