Clinical and morphological evaluation of gold micro shunt after unsuccessful surgical treatment of patients with primary open-angle glaucoma
In a 52-year-old man, 41 months after primary surgery, GMS+ was removed from the right eye because of the lack of IOP control despite of the maximal antiglaucoma therapy (Duotrav, Azopt). There were observed an increase of IOP to 41.0 mm Hg and progression in the visual field (MD=−4.23). No contact of the implant with the endothelium was observed. Collagen-rich connective tissue in the implant channels and dispersed chronic inflammatory infiltrations both around and inside the implant were detected. Lymphocytic infiltration (LCA+) was accompanied with clusters of numerous polynuclear giant cells ().
