Estimation of axial curvature of anterior sclera: correlation between axial length and anterior scleral curvature as affected by angle kappa
BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional de...
متن کاملRelationship between central corneal thickness, refractive error, corneal curvature, anterior chamber depth and axial length.
BACKGROUND To determine the relationship between central corneal thickness (CCT), refractive error, corneal curvature, anterior chamber depth and axial length in normal Taiwanese Chinese adults. METHODS Five hundred normal Taiwanese Chinese patients aged 40-80 years were recruited for the study. Measurement procedures included CCT, refractive error, corneal curvature, anterior chamber depth a...
متن کاملHeritability analysis of spherical equivalent, axial length, corneal curvature, and anterior chamber depth in the Beaver Dam Eye Study.
OBJECTIVE To examine genetic influences for quantitative refraction. Spherical equivalent and its related binary traits of myopia and hyperopia are highly correlated within families. Many linkage regions have been reported for myopia, high myopia, and quantitative refraction. However, the measured phenotype of spherical equivalent is in large part dictated by the relationship between the underl...
متن کاملCorrelation of axial length and corneal curvature with diopter in eyes of adults with anisometropia.
PURPOSE To analyze the causes of anisometropia. METHODS Between June 2011 and November 2012 101 participants were divided into three groups. The refraction comprising the degree of refractive errors in the presence of astigmatism which was converted into the degree of spherical equivalent as well as ocular axial length (AL), corneal curvature (CR), average corneal power (ave K) and diopters w...
متن کاملDistribution of axial length, anterior chamber depth, and corneal curvature in an aged population in South China
BACKGROUND Ocular biometry is important for preoperative assessment in cataract and anterior segment surgery. The purpose of this study was to investigate normative ocular biometric parameters and their associations in an older Chinese population. METHODS This was a cross-sectional observational study. From 2013 to 2014, we recruited inhabitants aged 50 years or older in Guangzhou, China. Amo...
