Increased prevalence of myopia in a ophthalmologic hospital in Goiânia – Goiás

Abstract

Aumento da prevalência de miopia em um serviço oftalmológico de referência em Goiânia-Goiás RESUMO Objetivo: Avaliar o aumento da prevalência de miopia entre pacientes atendidos em períodos diferentes em um serviço oftalmológico de Goiânia. Métodos: Foram comparados dados coletados em dois estudos científicos realizados em um serviço de oftalmologia, em diferentes períodos de tempo, que avaliaram dentre outros fatores, os erros refracionais dos participantes a partir destes dados comparou-se a porcentagem de pacientes portadores de miopia presentes nos estudos. Resultados: Observou-se um aumento na prevalência de Miopia dentre os participantes dos dois estudos. Na avaliação realizada entre 1995 e 2000 a porcentagem de pessoas com miopia representou 3,6% do total, já no estudo realizado no ano de 2014 a prevalência de pacientes com miopia foi de 9%. Dentre os pacientes com erros refracionais a prevalência de miopia no primeiro estudo foi de 9,97%, já no segundo a prevalência foi de 22%. Conclusão: Observou-se um aumento na prevalência de miopia entre os dois estudos, dados esses que corroboram com análises feitas que mostram um aumento da prevalência de miopia em todo mundo nos últimos 30 anos. Porém em uma proporção menor do que a observada em outros estudos populacionais.

Prevalence of Myopia Among Public School Children in Southern Brazil

“…Most school children had excellent uncorrected visual acuity and the prevalence of myopia is still low in comparison to other continents, but it seems to be consistently increasing overtime [13][14][15][16][17]. There was an increased risk of myopia in females, previously also described in the literature [45,46].…”

“…There is limited information regarding the prevalence of myopia in Brazil and this is the first study on myopia prevalence in southern Brazil [13,17]. Papers published previously in other regions used different methodology (no cycloplegia; retrospective analysis; adults included; patients from ophthalmology centers) [11,15,16]. The data collected in Porto Alegre is representative of public school children from the entire country in terms of the ethnic mix, since the proportion of Caucasians and Afrodescendants is similar to the national distribution [25].…”

“…There is little information about myopia in Brazil. Local studies have used different methodology, examined different populations and did not all use cycloplegia, which tends to overestimate myopia prevalence [13][14][15][16][17]. Vilar et al compared two studies conducted in the same ophthalmology hospital in Goiânia (Goiás) at different periods of time [16].…”

Garcia et al reported the prevalence of myopia among all refractive errors in Northeastern Brazil in 2001 was 13.3% in randomly selected students [14].…”
