Erol Can M, et al. – This study is performed to explore the impact of Helicobacter pylori (H. pylori) infection on choroidal thickness (CT) and retinal nerve fiber layer thickness (RNFLT). CT increases amid H. pylori infection and returns to the normal range within 6 weeks of treatment. RNFLT does not demonstrate any change amid H. pylori infection. The information identified with the subfoveal CT could be valuable in understanding the pathogenesis of central serous chorioretinopathy developing in H. pylori patients.
