RESUMO
Helicobacter pylori is a common gram-negative bacterium, which is associated with a variety of gastroenteric diseases, such as gastritis, duodenal ulcer and gastric cancer. Recent studies suggested a potential role of Helicobacter pylori in the pathogenesis of common ocular diseases, such as central serous chorioretinopathy, glaucoma, anterior uveitis and ocular adnexal lymphoma. Helicobacter pylori might affect the pathophysiological process of ocular diseases through oxidative damage, circulatory disorders and immune injury. Some studies also suggested that eradication of Helicobacter pylori had certain effects on some ocular diseases. This review aims to summarize current evidence of the Helicobacter pylori in the pathogenesis of common ocular diseases, so as to encourage innovative approaches in the prevention and treatment of these ocular diseases.
