Study design, rationale and methods for a population‐based study of myopia in schoolchildren: the Myopia Investigation study in Taipei

Abstract

Data from the MIT will provide population-based information concerning the prevalence, incidence and risk factors for myopia development among young schoolchildren in a metropolitan area of Taiwan.

Myopia Development Among Young Schoolchildren: The Myopia Investigation Study in Taipei

“…There was no significant difference in terms of the baseline demographic characteristics between the 11,590 analyzed participants and the whole target population. 29 At baseline, 7376 (3772 [51.1%] boys) were nonmyopes. A flowchart illustrating the subjects participating in each stage of the study is provided in the Figure. Of these, 6794 (3471 [51.1%] boys) were reexamined at least once, and the follow-up rate was 92.1%.…”

“…29 In brief, all grade 2 schoolchildren in Taipei City were invited to participate in the MIT study. A total of 20 hospitals and 54 private clinics joined the citywide program, collaboratively providing eye examinations for eligible participants.…”

“…To assess the development of myopia among these young schoolchildren, the Myopia Investigation Study in Taipei (MIT) was designed to provide a citywide eye examination program for grade 2 students of all elementary schools in Taipei City, with biannual follow-up examinations of this school cohort over 3 years. 29 This paper describes the first-year follow-up data from the MIT study and reports the incidence density and risk factors of newonset myopia among the nonmyopic participants at baseline.…”

Risk factors for myopia progression in second-grade primary school children in Taipei: a population-based cohort study

“…The study design, rationale and methods of the MIT have been published previously 15. In brief, the MIT project provided free vision and refraction evaluation once every semester for children who were older than 7 years but younger than 8 years in September 2013.…”

“…Each eye examination was performed in compliance with the standard operation procedure set by the MIT monitoring committee 15. Briefly, a slit lamp examination was performed to rule out anterior segment conditions that would contraindicate the use of cycloplegic agents in each child.…”
