Peripapillary retinal nerve fiber layer thickness variations with myopia.

Purpose: To determine the relationship between peripapillary retinal nerve fiber layer (RNFL) thickness and myopia using optical coherence tomography (OCT).

Design: Prospective observational case series.

Methods: One hundred thirty-two young males with myopia (spherical equivalent [SE], -0.

Optic disk ovality as an index of tilt and its relationship to myopia and perimetry.

Purpose: To examine the association of optic disk ovality with myopic refractive error, axial length, and the visual field.

Design: Prospective observational case series.

Methods: The study included 150 randomly recruited male subjects with myopia.

Use of optical coherence tomography to assess variations in macular retinal thickness in myopia.

Purpose: To investigate the variation in macular retinal thickness in otherwise normal young Asian myopic subjects by using optical coherence tomography (OCT).

Methods: One hundred thirty ophthalmically normal men 19 to 24 years of age with myopia (spherical equivalent, -0.25 to -14.

Prevalence, incidence, and progression of myopia of school children in Hong Kong.

Purpose: To determine the prevalence, incidence, and progression of myopia of Chinese children in Hong Kong.

Methods: A cross-sectional survey was initially conducted. A longitudinal follow-up study was then conducted 12 months later.

Localization of cortical cataract in subjects of diverse races and latitude.

Purpose: To compare the characteristics of early cortical cataract localization in three groups in cataract epidemiologic surveys performed in Reykjavík, Melbourne, and Singapore.

Methods: Individuals who had right eyes with an area of cortical opacity less than 20% of the pupil when dilated 7 mm or more were selected as subjects. This included 197 subjects from the Reykjavík Eye Study, 231 from the Vitamin E, Cataract, and Age-Related Maculopathy (VECAT) study in Melbourne, and 92 from the Singapore-Japan Cooperative Cataract Study, all showing early-stage cataract in pupils dilated to 7 mm or more.

A randomized trial of rigid gas permeable contact lenses to reduce progression of children's myopia.

Purpose: To test whether rigid gas permeable (RGP) contact lens wear can reduced the rate of myopia progression in school age children.

Design: Randomized clinical trial.

Setting: Single clinical center.

Prevalence of primary cornea guttata and morphology of corneal endothelium in aging Japanese and Singaporean subjects.

The purpose of the present study was to examine, in the aging people, racial and gender differences in the morphology of corneal endothelium as well as the incidence of cornea guttata in two Asian subject groups, one in Singapore and the other in Japan. Four hundred and sixty-five Chinese Singaporeans and 299 Japanese subjects (residents of Monzen-machi, Ishikawa Prefecture) aged 50 years and older were recruited for the study. Corneal endothelial abnormalities were diagnosed with slit-lamp biomicroscopy and specular microscopy.
