Ocular biometry and refraction in Mongolian adults.
OBJECTIVE To describe the variation in ocular biometry and its association with refraction in adult Mongolians. METHODS The study included 1800 subjects, aged 40 years or more, who were selected in two Mongolian provinces-Hövsgöl and Omnögobi-to participate in this population survey. Axial length (AL) and its components, as well as noncycloplegic autorefraction and corneal power (CP), were me...

PURPOSE To investigate longitudinal changes in refraction and biometry in Chinese adults. DESIGN Population-based prospective cohort study. METHODS 1817 subjects aged ≥ 35 years were randomly recruited from Yuexiu district, Guangzhou, China in 2008. Of which 1595 (87.8%) were reexamined in 2010 and 1427 (78.5%) were reexamined in 2014. Non-cycloplegic automated refraction and visual acuity ...
متن کاملAssociations of birth weight with ocular biometry, refraction, and glaucomatous endophenotypes: the Australian Twins Eye Study.
PURPOSE To examine the relationship of birth weight with ocular measures in a Caucasian twin population. DESIGN Cross-sectional study of 1498 twins (308 monozygotic and 441 dizygotic pairs) aged between 5 to 80 years participating in the Australian Twins Eye Study. METHODS All participants underwent ophthalmic examination including bilateral cycloplegic autorefraction, keratometry, interpup...
متن کاملSimultaneous measurements of refraction and A-scan biometry during accommodation in humans.
PURPOSE Accommodation is a dioptric change in power of the crystalline lens resulting from ciliary muscle contraction that leads to an increase in lens surface curvatures and thickness and changes in the position of lens surfaces. Previous studies have used A-scan ultrasound to measure changes in the position of lens surfaces with voluntary accommodation, but have not simultaneously measured th...
