“…Compared with studies conducted in Asia, our percentages were slightly lower than those estimated by the Nagahama Study in Japan, with a prevalence of myopia in adults aged 34 to 80 years of 49.97% 21 , while in adults aged 20-40 years in Saudi Arabia, there was a reported prevalence of 48.7% 22 , both with a SE ≤ -0.50 D as the definition of myopia. In Europe, there was an estimation of an overall prevalence of 30.6% in adults aged 25 to 89 years according to a meta-analysis that included 15 studies conducted in various countries 23 .…”

Purpose: To estimate the frequency of myopia in an adult population in Mexico City. Methods: Retrospective, cross-sectional and descriptive study. The spherical equivalent of the right eye was calculated from the refraction without cycloplegia obtained with an auto kerato-refractometer in patients examined during an ophthalmic health campaign carried out at the Instituto Nacional de Rehabilitación "Luis Guillermo Ibarra Ibarra" from January to March 2018. Results: We found a frequency of myopia of 45.21% with a cut-off value of ≤ -0.5 diopters of spherical equivalent in the 449 participants. Of these, 39.43% had mild myopia > -6.00 diopters, and 5.79% had high myopia ≤ -6.00 diopters of spherical equivalent. On the other hand, only 4 of the 449 examined patients had clinical signs of pathological myopia, making up 0.8% of the total sample. Of the remaining participants, 28.73% were classified as emmetropic and 26.05% as hyperopic, with a spherical equivalent ≥ 0.50 diopters. Conclusions: The frequency of myopia observed in our study is high and similar to that informed in previous reports in Mexican children and young adults, just as in some nations in Asia where myopia is a public health problem.

“…Regarding the high myopia figures obtained, with a total of 26 patients that resulted in 5.79% of all patients, they are still slightly lower than those reported by the Nagahama Study, with a prevalence of almost 7.89% using a SE ≤ -6.00 D 21 .…”

“…Genetic and prevalence data suggest that extreme myopia has a different origin than the more commonly seen childhood myopia, which is most likely largely driven environmentally. 9 – 11 In this respect, studies already demonstrate a strong association between the level of refractive error and myopic maculopathy across a wide range of myopic refractive errors, 7 , 8 and recent 6- and 12-year prospective longitudinal studies from Japan reported significant increases in the prevalence of different levels of myopia and associated pathology. 12 , 13 Hence, the incidence of myopia-related ocular complications and permanent vision impairment is very likely to significantly increase alongside the growing prevalence of myopia globally.…”

The International Myopia Institute's (IMI) mission is to advance research, education, and management of myopia to decrease future vision impairment and blindness associated with increasing myopia. Its approach is to bring together scientists, clinicians, policymakers, government members, and educators into the field of myopia to stimulate collaboration and sharing of knowledge. The latest reports are on pathologic myopia, the impact of myopia, risk factors for myopia, accommodation and binocular vision in myopia development and progression, and the prevention of myopia and its progression. Together with the digest updating the 2019 International Myopia Institute white papers using the research published in the last 18 months, these evidence-based consensus white papers help to clarify the imperative for myopia control and the role of environmental modification initiatives, informing an evidence-based clinical approach. This guidance includes who to treat and when to start or stop treatment, and the advantages and limitations of different management approaches.

Fue un estudio retrospectivo, transversal y descriptivo. Se calcularon los datos del equivalente esférico del ojo derecho de los pacientes examinados a partir de la refracción sin cicloplejia, determinada por medio de un autoqueratorrefractómetro durante la campaña de salud ocular que se llevó a cabo en el Instituto Nacional de Rehabilitación Luis Guillermo Ibarra Ibarra de enero a marzo de 2018. Resultados: La frecuencia de miopía encontrada en los 449 sujetos analizados fue del 45.21%, tomando como punto de corte un equivalente esférico ≤ -0.50 dioptrías; de ellos, el 39.43% tuvieron miopía leve (> -6.00 dioptrías) y el 5.79% miopía alta (≤ -6.00 dioptrías de equivalente esférico). Por otra parte, solo 4 de los 449 pacientes examinados presentaron datos clínicos de miopía patológica, conformando el 0.8% de la muestra total. De los participantes restantes el 28.73% fueron clasificados como emétropes y el 26.05% como hipermétropes con un equivalente esférico ≥ 0.50 dioptrías. Conclusiones: La frecuencia de miopía encontrada en nuestro estudio es alta y se asemeja a la de reportes previos en población mexicana infantil y de adultos jóvenes, así como a la de algunas naciones asiáticas donde la miopía es un problema de salud pública.
