PURPOSE To compare the accuracy of axial length vergence formulas versus refractive vergence formulas for secondary intraocular lens (IOL) implantation in pediatric aphakia. METHODS This retrospective comparative study, evaluated 31 eyes of 31 patients aged ≤3.5 years, who had undergone secondary IOL implantation. The median absolute error (MedAE) was compared between axial length vergence fo...

OBJECTIVE To investigate the association between subfoveal choroidal thickness in healthy southern Thailand volunteers and age, axial length, and refractive error. SUBJECTS AND METHODS This was a prospective cross-sectional case series. A total of 210 eyes of 105 healthy volunteers (86 women, age 23-83 years) in southern Thailand were examined with enhanced depth-imaging optical coherence tom...

AIMS To assess the longitudinal changes in biometric parameters and associated factors in young myopic children aged 7--9 years followed prospectively in Singapore. METHODS Children aged 7--9 years from three Singapore schools were invited to participate in the SCORM (Singapore Cohort study Of the Risk factors for Myopia) study. Yearly eye examinations involving biometry measures were perform...

BACKGROUND Angle closure glaucoma is emerging as a leading cause of blindness in Asia. OBJECTIVE To compare the ocular axial length of normal individuals and the subjects with primary angle closure glaucoma. This study has been conducted to determine axial length of eye as a risk factor of primary angle closure glaucoma. MATERIALS AND METHODS A cross-sectional comparative study was carried ...

PURPOSE To explore the association between axial length and retinal vascular network geometry (arteriovenous diameter ratio [AVR], arteriolar branching angles, and junctional exponents). DESIGN Prospective, cross-sectional study. METHODS Patients were recruited from a pseudophakic population that had preexisting axial length measurements. Mean arterial blood pressure and previous medical hi...

PURPOSE To estimate heritability and locate quantitative trait loci influencing axial length. DESIGN Classic twin study of monozygotic and dizygotic twins reared together. PARTICIPANTS Eight hundred ninety-three individuals from 460 families were recruited through the Twin Eye Study in Tasmania and the Brisbane Adolescent Twin Study (BATS) and had ocular axial length measured. METHODS Str...

PURPOSE To investigate spatial anisotropies in the peripheral visual field of axially myopic eyes, in an attempt to distinguish between models of isotropic and anisotropic ocular stretching. METHODS Stimuli consisted of two high-contrast Gaussian patches presented in one of four orientations (90 degrees, 180 degrees, 45 degrees, or 135 degrees). For each orientation, perceived separation was ...

OBJECTIVE The aim of this article is to study the effect of unilateral congenital cataract surgery on ocular growth and corneal flattening. METHODS This is a cross-sectional study of 59 patients operated on due to a unilateral congenital cataract. The median age of the patients at the time of diagnosis was 17 months (interquartile range, 5-39 months). The median age at cataract the time of su...

PURPOSE To assess the impact of axial length on the age-related peripapillary retinal nerve fiber layer (RNFL) thinning. METHODS This cross-sectional observational comparative case series included 172 eyes from 172 healthy Korean subjects. Peripapillary RNFL thickness was measured using an Optic Disc Cube 200 × 200 scan of spectral domain Cirrus HD OCT and the axial length was measured using ...
