Histological presence of Helicobacter pylori bacteria in the trabeculum and iris of patients with primary open-angle glaucoma.


PMID 22094712

Abstract

To investigate the role of Helicobacter pylori in primary open-angle glaucoma (POAG) pathophysiology by detecting its presence in eye biopsies of POAG patients during trabeculectomy. Fifty-one consecutive patients who underwent trabeculectomy for POAG not responsive to antiglaucoma therapy, and 35 consecutive anemic controls were examined for H. pylori presence mainly by gastric mucosa histology. In POAG patients, eye biopsies were also obtained and stained for H. pylori presence in situ. Forty-three of 51 (84.3%) POAG patients and 17 of 35 (48.6%) controls were tested H. pylori positive (p = 0.0004). In 5 H. pylori-positive POAG patients, H. pylori bacteria were identified in the trabeculum and iris specimens. For the first time, H. pylori bacteria have been detected histologically in eye biopsies of POAG patients.
