ABSTRACT
PURPOSE: to show how we diagnosed and treated a rarer form of angle-closure glaucoma; the pathogenic mechanism was angle crowding through thick peripheral iris roll. METHODS: we show the investigations: biomicroscopy of the fundus, tonometry, pachymetry, gonioscopy, perimetry, ultrasound biomicroscopy, optical coherence tomography of the anterior segment--that helped us to diagnose the angle-closure glaucoma and its pathogenic mechanism; we also show our choice for surgery--lens extraction--and our arguments for this choice. RESULTS: first postoperative day--intraocular pressure was 14 mmHg; a week postoperatively--intraocular pressure was 13 mmHg; three months postoperatively--intraocular pressure was 13 mmHg. CONCLUSIONS: lens extraction may be a very good choice in several forms of angle-closure glaucoma.
