purpose. To describe the association of ocular dimensions and refraction with
methods. This was a population-based cross-sectional survey of adult Chinese
aged 40 to 81 years residing in the Tanjong Pagar district in
Singapore. As part of the examination, ocular dimensions, including
axial length, anterior chamber depth, lens thickness, and vitreous
chamber depth, were measured using an A-mode ultrasound device. Corneal
radius and refraction were determined with an autorefractor, with
refraction further refined subjectively. Height (in meters) and weight
(in kilograms) were measured using a standardized protocol, and body
mass index (BMI) was calculated as weight divided by the square of the
height (kilograms per square meter).
results. Data on ocular biometry, refraction, height, and weight were available
on 951 (55.4%) participants with phakic eyes. After controlling for
age, sex, education, occupation, housing type, income, and weight, it
was found that taller persons were more likely to have longer axial
lengths (+0.23 mm longer axial length, for every 0.10 m difference
in height), deeper anterior chambers (+0.07 mm), thinner lenses (−0.09
mm), longer vitreous chambers (+0.26 mm), and flatter corneas (+0.09 mm
longer corneal radius), although refractions were similar. In contrast,
heavier persons tended to have more hyperopic refractions (+0.22 D for
every 10 kg difference in weight, +0.56 D for every 10
kg/m2 difference in BMI) but similar ocular dimensions.
conclusions. Adult height is independently related to ocular dimensions, but does
not appear to influence refraction. Thus, although taller persons are
more likely to have longer globes, they also tend to have deeper
anterior chambers, thinner lenses, and flatter corneas. Conversely,
weight is independently related to refraction, although the exact
biometric component responsible for this association is not
