ASENSIO-SANCHEZ, V.M. et al. Central serous chorioretinopathy as an extradigestive manifestation of helicobacter pylori gastric infection. Arch Soc Esp Oftalmol [online]. 2008, vol.83, n.3, pp.177-182. ISSN 0365-6691.
Objective: Helicobacter pylori (HP) gastric infection has been implicated as an important factor in occlusive arterial pathology. Nowadays, it is suspected that central serous chorioretinopathy (CSC) is due to a multifocal vascular occlusive disease of the choriocapillaris. The aim of this study was to determine the relation between gastric HP infection and CSC. Materials and methods: We evaluated a group of 16 patients with CSC and 20 controls. HP infection was assessed by the 13C-urea breath test (UBT). Clinical CSC diagnosis was confirmed by fundus biomicroscopy and fluorescein angiography. Results: Out of 16 patients with CSC, 11 (68.75%) were males and 5 (31.25%) females, with a mean age of 46.3 years. HP infection was positive in 11 patients (68.75%) and negative in 5 (31.25%). Men were HP-positive (HP+) in 72.7% of cases, compared to women who were HP+ in 60% of cases. The difference in prevalence of HP between the CSC-group (68.75%) and the control-group (30%) was found to be statistically significant (p< 0.05). HP+ patients had more gastric pain than HP negative (HP-) patients (72.73% vs 20%). Conclusions: These results indicate a possible statistical association between Helicobacter pylori gastric infection and CSC. HP should thus be considered a risk factor in CSC patients.
