Interocular Symmetry in Retinal Nerve Fiber Layer Thickness in Children: The Hong Kong Children Eye Study

Ophthalmology and Therapy, Journal Year: 2023, Volume and Issue: 12(6), P. 3373 - 3382

Published: Oct. 18, 2023

The aim of this work is to determine the interocular differences in peripapillary retinal nerve fiber layer (p-RNFL) thickness and its associations among school children Hong Kong. We conducted a population-based study including 4034 aged 6–8 years from Kong Children Eye Study (HKCES). All participants received comprehensive ocular examinations where p-RNFL was measured using spectral-domain optical coherence tomography (SD-OCT). degree symmetry between both eyes analyzed represented by intraclass correlation coefficient (ICC) values. Multivariable linear regression analysis used investigate systemic factors with difference. included mean age 7.61 ± 0.98 years. global 106.60 9.41 μm right 105.99 9.30 left eyes.

Compensatory Interactions between Corneal and Internal Astigmatism despite Lifestyle Changes

Children, Journal Year: 2024, Volume and Issue: 11(2), P. 154 - 154

Published: Jan. 25, 2024

This study explores whether children’s refractive errors and visual behaviors reverted to pre-COVID-19 levels a year after normal schooling resumed in Hong Kong as well the impact of corneal internal astigmatism on development. Vision survey data questionnaire results collected 2022 (n = 119) 2020 173) were compared. Cross-sectional showed similar proportions (cylindrical power ≥ 0.75 D) (49.1%) cohorts (55.5%). Despite 0.28 D increase astigmatism, compensatory 0.24 opposite direction kept relatively stable. The that children spent an additional 0.5 h/day outdoors weekends post-resumption but engaged more near-work activities, especially non-screen near-work, by approximately 1 both weekdays weekends. These findings supported longitudinal from 72 who participated surveys. highlights significant role changes. return in-person classes, total time increased remained high. underscore need for comprehensive strategies reduce high environmental risks error development children.
