ABSTRACT
Objective:The aim of the current study was to explore spatial and temporal distribution characteristics registered cases cataract surgery in China from 2013 2017.Methods: A database for analysis 2013-2017 established using ArcGIS10.0software as a platform data management presentation.Spatial autocorrelation undertaken, scan done SaTScan 9.5 software.Results: From 2017, annual rates (CSRs) were 1200, 1400, 1782, 2070, 2205 per 1 million population, indicating gradually increasing trend.Local Moran's I showed that there clustering CSR China, with Anhui being low-high region.Findings global hotspot Getis-Ord General G index national <0.01, Z = 1.12,P 0.26.Findings staged spatial-temporal indicated 18 areas aggregation found 2 stages.Observed differences each area statistically significant (P < 0.05).Conclusion: CSRs trend year by randomly distributed, clustering, reported region.However, high-risk still persist, requiring focused attention targeted prevention control measures.
