Prevalence of Infection in Patients with Central Serous Chorioretinopathy: A Review.

is a prevalent cause of gastrointestinal infections. Recently, several studies have shown a relationship between infection and a variety of extradigestive manifestations. The aim of this study was to review the literature regarding the prevalence of this infection in cases of central serous chorioretinopathy (CSR). We reviewed the EMBASE, Cochrane Library, and Google Scholar search engines; hand-searched many journals; and searched the cited references in published articles for relevant studies. We assessed 81 studies for eligibility. Finally, nine articles that met the inclusion criteria were included. The relationship between infection (as the etiologic factor) and chorioretinal involvement was assessed by the effect size with 95% confidence interval (CI). Both fixed- and random-effects models showed that the prevalence of infection in patients with CSR was significantly higher than in the control group (2.5-fold and 2.7-fold higher, respectively; P < 0.01). The results were not significantly different between the two models. Treatment of infection should be considered in patients with CSR. However, additional randomized controlled clinical trials are required to determine the possible role of eradication in the prognosis and treatment of patients with CSR.
