Annual Myopia Progression and Subsequent 2-Year Myopia Progression in Singaporean Children

Translational Vision Science & Technology, 2020
To investigate the association between 1-year myopia progression and subsequent 2-year myopia progression among myopic children in the Singapore Cohort Study of the Risk Factors for Myopia.This retrospective analysis included 618 myopic children (329 male), 7 to 9 years of age (mean age, 8.0 ± 0.8) at baseline with at least two annual follow-up visits.

Multicenter Validation of Machine Learning Models for Predicting Myopia Progression Across School‐Based Screening and Optical Intervention Settings in Chinese Children and Adolescents

Advanced Intelligent Discovery, EarlyView.
Machine‐learning models predict myopia trajectories from 12 routine ocular variables in 40 445 children across 10 hospitals. Externally validated across school‐based screening and optical‐intervention settings, the best models achieve AUROC 0.97 for myopia status and R2 0.83 for spherical equivalent, enabling personalized risk stratification to curb ...

Clinical management of progressive myopia [PDF]

Eye, 2013
Myopia has been increasing in prevalence throughout the world, reaching over 90% in some East Asian populations. There is increasing evidence that whereas genetics clearly have an important role, the type of visual environment to which one is exposed to likely influences the onset, progression, and cessation of myopia.

Improving access to new technologies: An experiment with Kenyan input sellers

American Journal of Agricultural Economics, EarlyView.
Abstract Agrodealers play a critical role in rural economies, selling essential inputs for agricultural production, stocking new products, and providing farmers with technical advice. However, uncertainty can discourage them from stocking newer, less familiar products, limiting the availability of innovative technologies and leading to market failures ...

Is it Possible to Slow the Progression of Myopia?

Annals of the Academy of Medicine, Singapore, 2004
The rates of myopia, including high myopia [spherical equivalent ≥-6 dioptres (D)], have been reported to be rising to epidemic proportions in Asia and solutions to this huge public health problem are urgently needed. Many researchers agree that myopia is not determined solely by genes and that environment may play a huge role.

Are dairy cows replaced too early? Evidence from a structural model and cow‐level data

American Journal of Agricultural Economics, EarlyView.
Abstract In past analyses of animal replacement decisions, studies have claimed that dairy farms often replace dairy cows too early to be maximizing profits. I estimate a structural model of asset replacement to determine the motives behind early replacement of dairy cows.
