The aim of this study was to systematically assess the causal relationship between AS and ocular inflammatory diseases.<h4>Methods</h4>We conducted a two-sample Mendelian randomization (MR) analysis to investigate the causal relationship between AS and several common ocular inflammatory diseases based on genome-wide association study (GWAS) data and public health data. Five methods, namely, inverse-variance weighted (IVW), MR-Egger, weighted median, weighted mode, and simple mode, were used. Sensitivity analysis was performed using MR-Egger intercept, Mendelian Randomization Pleiotropy Frontiers in genetics1372196https://www.ebi.ac.uk/biostudies/studies/S-EPMC11524906biostudies-literatureCausal relationship between ankylosing spondylitis and ocular inflammatory diseases: a Mendelian randomization study.PMC11524906Jiang YZhang YDong JWang YZhang CZhang QfalseCausal relationship between ankylosing spondylitis and ocular inflammatory diseases: a Mendelian randomization study.<h4>Background</h4>Observational studies have shown an increased risk of ocular inflammatory diseases in patients with ankylosing spondylitis (AS), but the genetically predicted association remains unclear.
