Five year incidence of visual field loss in adult Chinese. The Beijing Eye Study.

Purpose: To describe the cumulative 5 year incidence of visual field loss in adult Chinese in Greater Beijing.

Methods: The Beijing Eye Study 2006 included 3251 subjects (mean age 60.4±10.

[Colonic dripping with Taihuang liquid for treatment of neonatal hyperbilirubinemia].

Objective: To explore the clinical effects of colonic dripping with Taihuang liquid (THL) in treating neonatal hyperbilirubinemia (HBE).

Methods: One hundred and thirty-eight neonates with HBE were randomly assigned to two groups. Conventional treatment and nursing were given to both groups, and THL was given additionally to the observation group by colonic dripping.

[Single channel multifocal VEP studies in normal Chinese].

Objective: To investigate the waveform characters of single channel mVEP and its variability in normal Chinese people.

Methods: VERIS Science 4.3 system was used to record and analyze single channel mVEP.

[The value of frequency doubling perimetry in glaucoma screening of aged 40 or more population].

Objective: To investigate the diagnosis value of the frequency doubling perimetry (FDP) screening program in the aged 40 or more natural population-based glaucoma screening.

Methods: In 3 natural villages of Daxing District and 4 northern metropolitan communities of Beijing, 4439 subjects aged 40 or over were screened for glaucoma from May to October in 2001. The screening protocol C-20-1 of the frequency doubling perimetry (FDP) was used in all subjects.

[The prevalence and its screening methods of primary open angle glaucoma in defined population-based study of rural and urban in Beijing].

Objective: The purpose of the study is to determine the prevalence of primary open-angle glaucoma (POAG) in persons aged 40 or above in Beijing, China.

Methods: From June 2001 to October 2001, the screening population was identified by a door-to-door census in five metropolitan resident areas in the north of Beijing and three villages in a county south to Beijing. The screening included visual acuity, frequency doubling perimetry (FDP, C-20 screening program), non-contact tonometry, slit lamp microscopy, anterior chamber depth (Van Herick method), and fundus photography.

Analysis of human transforming growth factor beta-induced gene mutation in corneal dystrophy.

Background: Corneal dystrophy is a group of inherited blinding diseases of the cornea. This study was to identify the mutations of the keratoepithelin (KE) gene for proper diagnosis of corneal dystrophy.

Methods: Three families with corneal dystrophy were analysed.

[Prevalence of low vision and blindness in defined populations in rural and urban areas in Beijing].

Objective: To investigate the prevalence and causes of low vision and blindness in Beijing residents aged 40 and over.

Methods: 4,451 residents aged 40 and over in 3 rural communities and 5 urban communities in Beijing underwent eye examination, including examination of distant and near visual acuity (VA), best corrected distant and near VA, pinhole VA, and visual field, slit lamp biomicroscopy, and dilated ocular examination in the form of in-home survey by defined population-based sampling. The medical history was surveyed too.
