The utility of symptoms in identification of primary angle-closure in a high-risk population.

Objective: To examine the frequency of symptoms associated with primary angle closure in an East Asian population with high rates of disease.

Design: Population-based survey.

Participants: One thousand adults from rural and urban provinces of Mongolia were examined.

Anterior chamber depth in elderly Chinese: the Liwan eye study.

Purpose: To assess the anterior chamber depth (ACD) and its variation with age, gender, and angle width in elderly Chinese in an urban area of southern China.

Design: Cross-sectional study.

Participants: Adults 50 and older were identified using cluster random sampling in Liwan District, Guangzhou.

Prevalence of age-related maculopathy and age-related macular degeneration among the inuit in Greenland. The Greenland Inuit Eye Study.

Purpose: To examine the age- and gender-specific prevalence and describe the common phenotype of early age-related maculopathy (ARM) and late-stage age-related macular degeneration (AMD) among the Inuit in Greenland.

Design: Population-based cross-sectional study.

Participants: All > or =60-year-olds born in Greenland and living in the communities of Nuuk and Sisimiut, Greenland.

Sequels of Purtscher's retinopathy imaged by enhanced optical coherence tomography.

Purpose: To report the optical coherence tomography (OCT) findings in a case of Purtscher's retinopathy.

Methods: Enhanced optical coherence tomography, fundus photography, multifocal electroretinography.

Results: A 27-years-old female parachutist demonstrated outer retinal opacification with small intraretinal hemorrhages and corresponding binocular pericentric ring scotomata one day after suffering an unusually abrupt arrest of a free fall upon the unfolding of her parachute.

Strategy for decentralised prevention of angle closure glaucoma in Greenland.

In 1962 a blindness survey showed glaucomas to be responsible for 64% of all blindness in Greenland. In 1968 primary angle closure glaucoma was found to be the major glaucoma problem. Population studies using gonioscopy, optical anterior chamber depth, corneal thickness, diameter- and curvature measurements as well as ultrasound biometry were gradually performed.

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 measured.
