Application Of Big-Data For Epidemiological Studies Of Refractive Error, Michael Moore, James Loughman, John Butler, Arne Ohlendorf, Siegfried Wahl, Daniel Ian Flitcroft

Articles

Purpose

To examine whether data sourced from electronic medical records (EMR) and a large industrial spectacle lens manufacturing database can estimate refractive error distribution within large populations as an alternative to typical population surveys of refractive error.

Subjects

A total of 555,528 patient visits from 28 Irish primary care optometry practices between the years 1980 and 2019 and 141,547,436 spectacle lens sales records from an international European lens manufacturer between the years 1998 and 2016.

Methods

Anonymized EMR data included demographic, refractive and visual acuity values. Anonymized spectacle lens data included refractive data. Spectacle lens data was separated into lenses …

School Performance And Undetected And Untreated Visual Problems In Schoolchildren In Ireland; A Population-Based Cross-Sectional Study, Síofra Harrington, Peter Davison, Veronica O'Dwyer

Articles

This study explored the association between children’s vision and their school academic progress as reported by parents/guardians. Participants were 1,612 schoolchildren (722 6-7-year-olds, 890 12-13-year-olds) in randomly selected schools in Ireland. In advance of data collection, parents/guardians reported school performance as (a) much better than classmates (high-performance) (b) about the same as classmates (average-performance) (c) not as well as classmates (low-performance). Measurements included logMAR monocular visual acuities (with spectacles if worn, and pinhole) in the distance (3 m) and near (40 cm); the amplitude of accommodation; stereoacuity, colour vision assessment, and cyclopleged autorefraction. Controlling for confounders, children presenting with visual …
