Retinal vascular diameters in relation to physical activity in Danish children - The CHAMPS Eye Study.

Our objective was to determine associations between retinal vascular caliber and physical activity (PA) in a school-based child cohort. In a prospective study, we created a childhood cumulative average PA-index using objectively measured PA (accelerometry) assessed at four periods between 2009 and 2015. Cumulative exposure to PA intensities was estimated.

Choroidal thickness and myopia in relation to physical activity - the CHAMPS Eye Study.

Purpose: To describe the relationship between choroidal thickness (CT) and myopia in relation to physical activity (PA) in a population-based child cohort.

Methods: In a prospective study of 307 children from the CHAMPS Study Denmark, we used objective data from GT3X accelerometer worn at four periods between 2009 and 2015 to determine the amount and intensity of PA. Intensity was estimated as counts/minutes, and cut-off points were defined at four intensity levels.

Physical activity and myopia in Danish children-The CHAMPS Eye Study.

Purpose: To determine associations between physical activity (PA) and myopia in Danish school children and investigate the prevalence of myopia.

Methods: This is a prospective study with longitudinal data on PA in a Danish child cohort. Physical activity (PA) was measured objectively by repeated ActiGraph accelerometer measurement four times with different intervals (1-2.

Genetic and environmental effects on myopia development and progression.

This review aims at elucidating the interaction between genetic and environmental factors in the aetiology of primarily low myopia. Genetics greatly influence the growth of the eye, but the fine correlation between the components of refraction for the eye to become emmetrope is affected by environmental factors such as education, metabolism, physical activity, and outdoor activity.

Epibulbar lipodermoids, preauricular appendages and polythelia in four generations: a new hereditary syndrome?

A new syndrome with abnormalities along the first branchial arch and the milk list is described in a family of four affected generations. The characteristics of the syndrome are epibulbar lipodermoids, preauricular appendages and polythelia. The expressivity varies but all affected have supernumerary nipples and preauricular manifestations while visible epibulbar lipodermoids do not seem obligatory.

Ocular anisometropia and laterality.

Purpose: To study the difference in refraction between right and left eyes (anisometropia) in different age groups, look for evidence of eye laterality (more refractive error in one eye) and compare the size of anisometropia in the myopic and emmetropic ranges.

Methods: The study was based on children in Hong Kong (examined at the age of 6 years and again at the age of 8.5 years) and their parents (aged 26-60 years).

The mystery of myopia.

Published data from all parts of the world show that myopia is rare before school age, gradually increases during school life and reaches its highest level of prevalence during the years of most intense study at university. It is widely held that continuous reading harms the eyes, but none of the attempts made so far to reduce accommodative fatigue by introducing pauses during reading and teaching, eye exercises, etc. have been successful in reducing the number of children who develop myopia.

Myopia in humans: can progression be arrested?

The multiplicity of theories regarding the aetiology of myopia has led to numerous and partly contradictory methods of therapy. Interest has been focused on accommodation because of the established association between myopia and close work. In studies of drug treatment of myopia, the treatment is often reported to be effective but the lack of randomization and high drop-out rates make the results questionable.
