Clinical and morphological evaluation of gold micro shunt after unsuccessful surgical treatment of patients with primary open-angle glaucoma
A 90-year-old man with GMS removed from the right eye 29 months after implantation. IOP was 25.0 mm Hg (Ganfort), and progression in the visual field was observed (MD=−17.91). The central corneal thickness (CCT) increased from 480 to 568 μm and the corneal decompensation was detected despite the lack of GMS contact with the endothelium (OCT Visante). In the middle portion of GMS the presence of collagen-rich connective capsule-like reaction about 100-μm thick was found (). The presence of cell-rich collagen-poor connective tissue was also found between the plates. There were also observed chronic inflammatory infiltration cells, polynuclear giant cells, and small blood vessels ().
