This multi-ethnic study found that parental myopia was a risk factor for myopia development in pre-school age children. The age the parents became myopic themselves had a dose-dependent effect in their children if both parents had onset of myopia before age 12. Eye care practitioners can use this to identify which children may benefit from early myopia treatment intervention.
The majority of parents are unaware of the importance of myopia intervention. What can we do when parents insist on myopia undercorrection for their child? In this case we cover the communication approaches, and also consider the parents’ point of view to achieve the best possible outcomes for their child, as our patient.
This systematic review of 9 studies confirms that under-correction of myopia does not slow progression; rather, at least half of the studies have shown the myopia progression is accelerated. There was no benefit found in overcorrection, and the evidence for un-correction was equivocal. Clinically, this advocates for the full correction of myopia.
What amount of axial length growth be expected in myopes versus emmetropes, and how can you tell if your myopia control treatment is working? This important clinical reference provides all this information and more on axial growth in younger and older children, emmetropes and myopes, and even data on typical myopia stabilization.
Myopia control is vital for children with fast myopia progression. What are the key risk factors for faster myopia progression? What clinical findings indicate a more proactive myopia management strategy may be required? This case describes risk factors and evidence-based treatment options for fast myopia progressors.
Considering even emmetropic eyes elongate, what are the limits of myopia control efficacy? This novel analysis explores the absolute axial elongation of treated and untreated myopes in the MiSight 3-year clinical trial in comparison to previously published models of myopic and emmetropic eye growth. The results indicate a potential limit to the short-term percentage efficacy of myopia control treatments.
Previous multi-ethnicity studies have shown ‘normal’ axial elongation in emmetropic children to be around 0.1mm / year. In this study, 700 Chinese schoolchildren with stable emmetropia showed 0.2mm per year axial elongation from age 7-11, which reduced with age and ceased at age 15. This appears higher than measured in Singaporean Chinese children in the SCORM study, 20 years ago.
Young adults wearing the spectacle-mounted Clouclip device to measure viewing behaviour and light exposure also kept an activity diary. Mean daily near work and outdoor time were subjectively reported at about 150% of the objectively measured hours. This indicates the value of objective measures in research, as well as for clinical education and behaviour modification tools in future.
