To investigate the potential association between gut microbiota and central serous chorioretinopathy (CSC), we have observed in our clinical practice that CSC patients often experience chronic gastrointestinal issues. This observation has led us to hypothesize that CSC may be associated with gut dysbiosis. The Bifidobacterium genus is widely recognized as a beneficial gut bacterium, and numerous well-established Bifidobacterium supplements are available on the market. To explore this possible connection, we will collect fecal samples from both CSC patients and healthy individuals. Using whole-metagenome shotgun sequencing, we will compare the gut microbiota compositions of the two groups to determine if significant differences exist. Additionally, we will randomly assign patients to two groups: one group will receive Bifidobacterium supplements for at least one month, while the other group will receive a placebo. We will then assess whether the group receiving the supplements experiences faster recovery and lower relapse rates compared to the placebo group.
