The Association Between Time Spent On Screens And Reading With Myopia, Premyopia And Ocular Biometric And Anthropometric Measures In 6- To 7-Year-Old Schoolchildren In Ireland, Síofra Harrington, Veronica O'Dwyer

Articles

Purpose More time spent on near tasks has consistently been associated with the promotion of myopia. The World Health Organization advises limiting daily screentime to less than 2 h for children aged five and over. This study explored the relationship between time spent on screens and reading/writing with refractive status, ocular biometric and anthropometric factors in 6-to 7-year- olds in Ireland.

Methods Participants were 723 schoolchildren (377 boys [51.8%]), mean age 7.08 (0.45) years. The examination included cycloplegic autorefraction (1% cyclopentolate hydrochloride), ocular biometry (Zeiss IOLMaster), height (cm) and weight (kg). Screentime and reading/writing time were reported by parents/legal guardians …

Prescribing Patterns Of Myopia Control Contact Lenses Among Optometrists In Ireland, Michael Moore, Daniel Ian Flitcroft, James Loughman

Articles

Purpose

This retrospective analysis of electronic medical record (EMR) data investigated the prescribing patterns of soft myopia control contact lens (MCCL) treatments since their introduction in Ireland in 2017.

Methods

Anonymised EMR data were sourced from 33 optometry practices in Ireland from 2017 to 2021 to determine the number of practices prescribing MCCLs to myopic children 5–18 years old. In MCCL-prescribing practices, the proportion of contact lens wearing children fitted with MCCLs and the proportion of progressive (≤−0.25 D/year) myopic children fitted with MCCLs were determined. Logistic regression was used to determine which factors influenced the likelihood of being prescribed …

The Future Of Clinical Trials Of Myopia Control, Mark A. Bullimore, Noel A. Brennan, Daniel I. Flintcroft

Articles

In the field of myopia control, effective optical or pharmaceutical therapies are now available to patients in many markets. This creates challenges for the conduct of placebo-controlled, randomised clinical trials, including ethics, recruitment, retention, selective loss of faster progressors and non-protocol treatments: 1. Ethics: It is valid to question whether withholding treatment in control subjects is ethical. 2. Recruitment: Availability of treatments is making recruitment into clinical trials more difficult. 3. Retention: If masking is not possible, parents may immediately withdraw their child if randomised to no treatment. 4. Selective loss: Withdrawal of fast progressors in the control group leading …

Myopia is a dynamic and rapidly moving field, with ongoing research providing a better understanding of the etiology leading to novel myopia control strategies. In 2019, the International Myopia Institute (IMI) assembled and published a series of white papers across relevant topics and updated the evidence with a digest in 2021. Here, we summarize findings across key topics from the previous 2 years. Studies in animal models have continued to explore how wavelength and intensity of light influence eye growth and have examined new pharmacologic agents and scleral cross-linking as potential strategies for slowing myopia. In children, the term premyopia …

Choroidal Thickness Profiles And Associated Factors In Myopic Children, Emmnuel Kobia Acquah, Daniel Ian Flitcroft, Gareth Lingham, Nabin Paudel, James Loughman

Articles

SIGNIFICANCE: This study addresses the lack of choroidal thickness (ChT) profile information available in European children and provides a baseline for further evaluation of longitudinal changes in ChT profiles in myopic children as a potential biomarker for myopia treatment and identifying children at risk of myopic progression.

PURPOSE: This study aimed to investigate ChT profiles and associated factors in myopic children.

METHODS: Baseline data of 250 myopic children aged 6 to 16 years in the Myopia Outcome Study of Atropine in Children clinical trial were analyzed. Choroidal thickness images were obtained using swept-source optical coherence tomography (DRI-OCT Triton Plus; Topcon …

Changes In Refractive Error During Young Adulthood: The Effects Of Longitudinal Screen Time, Ocular Sun Exposure, And Genetic Predisposition, Samantha Sze-Yee Lee, Gareth Lingham

Articles

Changes in refractive error during young adulthood is common yet risk factors at this age are largely unexplored. This study explored risk factors for these changes, including gene–environmental interactions.

Current image captioning models produce fluent captions, but they rely on a one-size-fits-all approach that does not take into account the preferences of individual end-users. We present a method to generate descriptions with an adjustable amount of content that can be set at inference-time, thus providing a step toward a more user centered approach to image captioning.

Distribution Of Axial Length In Australians Of Different Age Groups, Ethnicities, And Refractive Errors, Vinay Kumar Nilagiri, Samantha Sze-Yee Lee, Gareth Lingham, Jason Charng, Seyhan Yazar, Alex W. Hewitt, Lynn R. Griffiths, Paul G. Sanfilippo, Tzu-Hsun Tsai, David A. Mackey

Articles

Treatments are available to slow myopic axial elongation. Understanding normal axial length (AL) distributions will assist clinicians in choosing appropriate treatment for myopia. We report the distribution of AL in Australians of different age groups and refractive errors.
