Variations of dry eye disease prevalence by age, sex and geographic characteristics in China: a systematic review and meta-analysis.

ABSTRACT: Dry eye disease (DED) is one of the most prevalent ocular diseases in the world. In China, new lifestyles driven by information technology and the rapid ageing process have brought DED a severe public health concern. The aim of our study was to obtain the pooled prevalence of DED in China and explore its potential correlates.A comprehensive systematic review was conducted to identify all relevant literature published since 1990. Meta-analysis and meta-regression approaches were adopted to estimate the prevalence of DED. The number of people with DED was obtained by multiplying the corresponding demographic data in 2010.Advanced age, female sex and larger latitude were significant risk factors for DED by symptoms and signs, whereas only advanced age was positively associated with an increased prevalence of DED by symptoms. In 2010, the prevalence of DED by symptoms and signs were 13.55% (95% CI?=?10.00-18.05) and that of DED by symptoms was 31.40% (95% CI?=?23.02-41.13) in Chinese people aged 5-89 years, corresponding to a total of 170.09 million (95% CI?=?125.52-226.63) and 394.13 million (95% CI?=?288.99-516.30) affected individuals respectively.The huge burden of DED in China calls for more public health attention and actions. Improved epidemiological studies on DED prevalence are still urgently needed.

Project description:Importance:Uncorrected refractive error (RE) is a leading cause of visual impairment, and variations in ocular anatomy determine RE. The unique ocular determinants of RE in Chinese American individuals have not been studied previously. Objective:To report ocular determinants of RE in a Chinese American population 50 years and older in Monterey Park, California. Design, Setting, and Participants:The Chinese American Eye Study, a population-based, cross-sectional study, was conducted from February 1, 2010, through October 31, 2013, in Monterey Park, with this particular data analysis performed from January 1 through December 31, 2016. This study included data from 4582 participants who underwent an eye examination to obtain axial length (AL), central corneal thickness, vitreous chamber depth (VCD), anterior chamber depth (ACD), lens thickness (LT), corneal power (CP), noncycloplegic subjective refraction, and lens nuclear opalescence (NOP) grading. Data from the right phakic eye of each participant were used. Multiple regression models (standardized regression coefficients [SRCs] and semipartial correlation coefficients squared [SPCCs2]) identified key determinants of RE. Main Outcomes and Measures:Ocular determinants of RE. Results:Among the 4071 participants eligible for analysis (1496 men [36.7%] and 2575 women [63.3%]; mean [SD] age, 60.5 [8.1] years), mean (SD) RE was -0.52 (2.95) diopters (D), with no sex-related difference. A hyperopic shift occurred in women from -0.62 (2.95) D at 50 to 59 years to 0.60 (1.62) D at 80 years or older and in men from -0.69 (3.00) D at 50 to 59 years to 0.40 (2.29) D at 80 years or older (P < .001 for both). Compared with men, women had shorter AL (mean [SD], 23.62 [1.34] vs 24.14 [1.27] mm; P = .006), shorter ACD (mean [SD], 3.33 [0.34] vs 3.44 [0.34] mm; P < .001), and steeper CP (mean [SD], 43.50 [1.52] vs 42.88 [1.45] D; P = .02), after adjusting for age and height. No sex differences were found in VCD, LT, and NOP after height adjustment. Compared with younger individuals, older individuals had shallower ACD, thicker LT, and more NOP compared with younger individuals (P < .001 for both), even after adjustment for height. Axial length was the strongest determinant of RE (SRC = -0.92; SPCC2 = 0.55), followed by CP (SRC = -0.43; SPCC2 = 0.15). When individual components of AL were evaluated, VCD had the greatest contributing effect (SRC = -0.99; SPCC2 = 0.52), followed by CP (SRC = -0.47; SPCC2 = 0.15) and LT (SRC = -0.29; SPCC2 = 0.06). Conclusions and Relevance:These data suggest that Chinese American individuals have longer AL and greater contribution of AL to RE than do Latino and other Chinese populations. Future studies should explore risk factors for increased AL in Chinese Americans and potential interventions that may ultimately prevent myopia-related disease.
