Comparison of four different orthokeratology lenses in controlling myopia progression

Myopia is the most common form of ametropia and one of the leading causes of vision impairment in the world [1]. Estimates show that in the early 21st century, myopia affected almost 30 % of the world ’s population [2]. This trend is projected to increase significantly, affecting nearly 50 % of the world’s population by 2050 [3].

ConclusionsIn emmetropia body growth and axial elongation are correlated. In participants with myopia, body growth appears to stabilise whilst axial elongation continues at a much faster rate indicating dysregulation of normal ocular growth.ResumenIntroducciónLa estatura y la longitud axial (LA) se incrementan durante la infancia, derivando en miopía el exceso de elongación axial. No existe consenso acerca de la asociación entre crecimiento corporal y LA durante el desarrollo refractivo. Este estudio exploró la asociación entre los cambios de estatura, LA y estatus refractivo a lo ...

We present a 10-year review of children attending a secondary and tertiary eye care facility in London, focussing on the proportion of glasses prescriptions for myopia and progression rates.Methods: We collated refraction and demographic data from children under the age of 17 years seen at Moorfields Eye Hospital, London, UK, between 2008 and 2017.Results: We included 63,854 datasets from 23,593 children (51.2% boys, median age 5.4 years, interquartile range IQR 3.8–7.1). The proportion of myopic prescriptions increased from 24 to 32%. In n = 3355 with initial mild/moderate myopia, median progression rate was &...

CONCLUSION: The prevalence of choroidal neovascularization in eyes with diabetic retinopathy is very low, with a lower prevalence of age-related macular degeneration. Diabetic choroidopathy plays a significant role in formation of choroidal neovascularization in eyes with diabetic retinopathy. PMID: 31984769 [PubMed - as supplied by publisher]

This study included right eyes of 857 bilaterally highly myopic individuals from the ZOC-BHVI Cohort Study. Participants underwent examinations, including BCVA, ocular biometry, autorefraction, and color fundus photography. An Early Treatment Diabetic Retinopathy Study grid was applied on the fundus photographs to evaluate the location of DCA, which was graded into four categories (D0–D3). The characteristics and ocular biometry were compared between participants' eyes with and without DCA. Results: Diffuse chorioretinal atrophy was found in 177 (20.6%) eyes. The proportion of participants with DCA in age groups o...

Conclusion: Vitamin A deficiency prevalence was much higher indicating missed opportunities for vitamin A supplementation at a younger age. Refractive error was more prevalent in the urban population as well in the older age group (11–15 years), indicating a need for frequent eye screening.

KlaverAbstractEnvironmental factors are important in the development of myopia. There is still limited evidence as to whether computer use is a risk factor. The aim of this study is to investigate the association between computer use and myopia in the context of other near work activities.Within the birth cohort study Generation R, we studied 5074 children born in Rotterdam between 2002 and 2006. Refractive error and axial length was...
