The Distribution of Ocular Normative Parameters in a Spanish School Population

Journal of Clinical Medicine, Journal Year: 2025, Volume and Issue: 14(7), P. 2507 - 2507

Published: April 7, 2025

Background/Objectives: The prevalence of myopia is increasing globally, including in Spain. early detection ocular biometric parameters associated with development crucial for implementing control strategies. This study aims to describe the normative values a Spanish school-aged population and compare them previously established reference data. Methods: A cross-sectional, observational, analytical was conducted on 558 students aged 6 12 years from Educare Valdefuentes School Madrid. Ocular parameters, axial length (AL), corneal curvature (CR), anterior chamber depth (ACD), crystalline lens thickness (LT), (CCT), posterior vitreous (PVD), were measured using IOLMaster 700. length/corneal radius (AL/CR) ratio calculated. Percentile growth curves generated, results statistically analyzed IBM SPSS 29. Results: AL significantly increased age (p < 0.001), boys had longer than girls. AL/CR showed moderate correlation risk (ρ = 0.647, p 0.001). Compared previous European studies, no significant differences found, except minor variations CR. Conclusions: These percentile-based provide useful monitoring assessing children. remains strong predictor development, supporting its role

Orthokeratology in controlling myopia of children: a meta-analysis of randomized controlled trials

BMC Ophthalmology, Journal Year: 2023, Volume and Issue: 23(1)

Published: Oct. 31, 2023

Abstract Background Delaying the development and lowering progression of myopia in children is focus current ophthalmology researches. We aimed to evaluate role orthokeratology controlling children, provide insights clinical treatment care with myopia. Methods Two investigators searched The Cochrane Library, Embase, Pubmed, China national knowledge infrastructure, biomedical literature database, WanFang Weipu databases for randomized controlled trials(RCTs) on up November 5, 2022. researchers independently searched, screened extracted studies according inclusion exclusion standards. RevMan5.3 software was used statistical analysis. Results A total 14 RCTs involving 2058 were included this meta-analysis. Synthesized outcomes indicated that improved uncorrected visual acuity(MD = 0.40, 95%CI: 0.05 ~ 0.74), reduced diopter change(MD=-3.19, -4.42~-1.95), changes corneal curvature(MD=-3.21, -3.64~-2.79), length ocular axis (MD=-0.66, -1.27~-0.06) amount change(MD=-0.42, -0.64~-0.21) after 1 year wearing orthokeratology(all P < 0.05). Besides, change (MD=-3.22, -4.86~-1.58), (MD=-1.15, -2.25~-0.06) 2 (MD=-0.53, -0.96~-0.11) (all No publication biases found amongst synthesized > Conclusions Orthokeratology delays long-term effects need further investigations future studies.

Corneal Characteristics of Myopic Malay School Children and Their Association with Axial Length

Clinical Optometry, Journal Year: 2024, Volume and Issue: Volume 16, P. 107 - 114

Published: April 1, 2024

Corneal characteristics are unique to each eye and can vary among different levels of refractive errors. However, minimal data available in the literature on corneal myopic Malay school children including difference between low group moderate group. Therefore, this study aims determine their associations with axial length.
