Prevalence of age-related macular degeneration in an elderly urban chinese population in China: the Jiangning Eye Study.

Abstract:

PURPOSE:To describe the prevalence of AMD in an elderly urban Chinese population in China. METHODS:A population-based, cross-sectional study was conducted using a cluster random sample of residents aged 50 years or older living in the Jiangning Road Subdistrict, Jing'an District, Shanghai, China. All participants underwent a standardized interview and comprehensive eye examinations, including digital retinal photography and spectral-domain optical coherence tomography (OCT) examinations of both eyes between November 2012 and February 2013. Trained graders assessed the presence and severity of AMD lesions based on a modified version of the Wisconsin Age-Related Maculopathy Grading System. RESULTS:Of the 2044 subjects who participated (82.5% response rate), 2005 had fundus photographs and OCT results of sufficient quality for grading of AMD signs. Early and late AMD were present in 206 (10.3%) and 23 (1.1%) participants, respectively. After age standardization, the prevalence of early AMD in Chinese persons aged 50 years or older was 9.5% (95% confidence interval [CI], 8.2-10.8) and that of late AMD was 1.0% (95% CI, 0.5-1.5). CONCLUSIONS:The prevalence of early and late AMD in this urban Chinese sample was higher than that reported in the Beijing and Handan studies. Age-related macular degeneration is highly prevalent among the elderly urban Chinese population in mainland China. : Chinese Abstract.

  • Change in full-field ERGs after macular translocation surgery with 360 degrees retinotomy.

    abstract:PURPOSE:One of the methods used in macular translocation (MT) surgery for subfoveal neovascularization is to create a temporary total retinal detachment followed by a 360 degrees retinotomy. The whole retina is then shifted from the original surface of the retinal pigment epithelium (RPE), resulting in an unusual retin...
