Why Myopia Matters: 5 Things to Know Why Myopia Matters: 5 Things to Know

Half of the world's population is projected to be myopic by 2050. Here are two facts to know about this common cause of impaired vision, along with three strategies to respond to its rising incidence.Medscape Ophthalmology

Publication date: Available online 17 July 2019Source: Journal of Health EconomicsAuthor(s): Audrey Guo, Jonathan ZhangAbstractA fundamental question in health insurance markets is how do health care consumers dynamically optimize their medical utilization under non-linear insurance contracts? Our paper tests the neoclassical prediction that a fully forward-looking agent only responds to their expected end-of-year price. Our unique identification strategy studies families during the year of childbirth who will likely satisfy their annual deductible, thereby knowing their expected end-of-year price. We find that during the ...

me JM, Queirós A Abstract Purpose: Contact lenses used for myopia control incorporate variable power distribution across the optic zone potentially creating degradation of the high order aberrations. The present study aims to evaluate the retinal image quality and visual performance in three prototypes of contact lenses intended to control axial elongation of the eye before they are considered for clinical trials. Methods: This is a non-dispensing cross-over, double blind study where 30 right eyes of myopic subjects worn 3 multifocal test lenses and 1 monofocal control lens in random order. Lens 1 was a Rad...

CONCLUSION: Preoperative refractive error significantly affects pupil diameter in highly myopic eyes after implantable collamer lens implantation. Pupils of super highly myopic eyes remained smaller than preoperative levels under mesopic conditions after implantable collamer lens implantation. PMID: 31304777 [PubMed - as supplied by publisher]

ConclusionICC is seen in 55.8% of highly myopic eyes with the presence of focal CRA or myopic conus and/or presence of intrascleral vessels near the cavitation. These findings suggest that patchy atrophy affects the scleral contour within posterior staphyloma beyond the funduscopically identified patchy atrophy by ICC. The presence of intrascleral vessels could also contribute to the ICC development. Eyes with patchy CRA or myopic conus needs to be checked on further follow-up visits for the development of macular or peripapillary ICC.

CONCLUSIONS: We confirmed ZC3H11B as a susceptibility gene for high and extreme myopia, and ZFHX1B and SNTB for extreme myopia in Chinese populations. Instead of myopia onset, these three genes were more likely to impose risks of progressing to high and extreme myopia. PMID: 31300455 [PubMed - as supplied by publisher]

Authors: Choo HG, Rah SH, Kim SH Abstract Purpose: To investigate the association between regional solar radiation and myopia occurrence in South Korean children. Materials and Methods: A population-based cross-sectional study using data of 1218 children aged 7-9 years from the Korea National Health and Nutritional Examination Survey was conducted from January 1, 2008, to December 31, 2012. Myopia prevalence and the mean spherical equivalent were estimated; myopia was defined as spherical equivalent refraction

Authors: Salmerón-Campillo RM, Jaskulski M, Lara-Cánovas S, González-Méijome JM, López-Gil N Abstract Specially developed software (app) was written for handheld electronic devices that uses the device camera and light detector for real-time monitoring of near-work distance and environmental lighting. A pilot study of this novel app employed children using tablet computers in a classroom. Measurements of face-device distance and face illuminance were obtained from two schools where tablets were used regularly. Children were divided randomly into a control group (CG) and interventi...
