Purpose: To compare trabeculectomy with mitomycin C (trab-MMC) and XEN45 Gel Stent placed ab externo with open conjunctiva (XGS AEO) with or without cataract surgery in patients with glaucoma.
Design: Nonrandomized, retrospective, comparative study.
Subjects: A total of 204 eyes from 204 glaucoma patients who received XGS AEO or underwent trab-MMC with or without cataract surgery between July 2018 and August 2021 at Massachusetts Eye and Ear.
Prcis: Ab externo with open conjunctiva placement may lead to improved gelatin stent (XEN Gel Stent; Allergan) success rate compared with ab interno with closed conjunctiva because it conferred more favorable intraocular pressure (IOP) and medication burden reduction based on our complete and qualified success criteria.
Purpose: To compare outcomes of a gelatin stent (XEN 45 Gel Stent; Allergan) placed either ab interno with closed conjunctiva (AIC) or ab externo with open conjunctiva (AEO) with or without cataract surgery in patients with glaucoma.
Design: Retrospective, nonrandomized comparative study of 85 eyes from 85 glaucoma patients who received XEN 45 Gel Stent placed either AIC (N=32) or AEO (N=53) with or without cataract surgery between July 2018 and January 2022 at Massachusetts Eye and Ear.
Predicting the visual outcome after cataract extraction can be challenging in glaucoma patients who develop cataracts. Here, we demonstrate the case of a patient with advanced glaucoma and a mild-to-moderate cataract at initial presentation, who demonstrated remarkable improvement in visual acuity following a period of controlled intraocular pressure (IOP) and the removal of a matured cataract at the time of surgery. A 64-year-old Haitian woman with severe mixed-mechanism glaucoma and hand motion vision in both eyes (OU) presented with intraocular pressures of 38 mmHg OD (oculus dexter/right eye) and 41 mmHg OS (oculus sinister/left eye) while on three IOP-lowering agents.
