Background: To describe a case of retinal pigment epithelial tears (RPE tears) and serous retinal detachment (SRD) after Ex-PRESS filtration surgery for primary open-angle glaucoma (POAG) combined with ischemic optic neuropathy. . This case report involved a 69-year-old woman who underwent Ex-PRESS filtration surgery for right POAG. She had a history of systemic arteriosclerotic disease and subacute progressive visual field loss due to suspected ischemic optic neuropathy in her right eye. The right preoperative visual acuity was 0.7, and intraocular pressure (IOP) was 19 mmHg with maximum glaucoma eye drops. RPE detachment was not observed in the fundus. On day 9 after surgery, the IOP was 6 mmHg, and mild choroidal detachment was observed. On day 13, although IOP remained almost unchanged at 7 mmHg, bullous SRD was observed in the inferior retina, including the macula, and RPE tears were observed along the superior arcade vessel. While subretinal fluid gradually decreased with increasing IOP, tractional retinal folds persisted along the superior arcade, accompanied by macular degeneration.
Conclusion: We experienced a case of RPE tears after Ex-PRESS filtration surgery. In addition to choroidal detachment in the setting of hypotony, a pathologic condition causing structural fragility of the RPE layer may contribute to the development of RPE tears.

Background: This study aimed to evaluate the clinical correlative factors and outcomes of treatment of bleb-associated endophthalmitis (BAE) following glaucoma filtration surgery in a Chinese population from the year 2012 to 2022, and to compare them with the clinical course during the coronavirus disease (COVID-19) pandemic period.
Methods: This was a retrospective analysis of consecutive cases of BAE treated at the Eye & ENT Hospital of Fudan University, Shanghai, China, between January 1, 2012, and December 31, 2022. The clinical presentation, treatment modality, microbiological data, clinical course, and outcomes of visual acuity (VA) and intraocular pressure (IOP) in all BAE cases were collected and analyzed.

Background: The most common retinal complications after glaucoma surgery are choroidal detachment, hypotony maculopathy, malignant glaucoma, vitreous hemorrhage, endophthalmitis and retinal detachment. However, if glaucoma surgery is a risk factor for the ERM development needs to be clarified. This study aims to assess the incidence of epiretinal membrane (ERM) in 2 years of follow-up in patients with primary open-angle glaucoma (POAG) treated with Ex-Press shunt implant.

Purpose: Iridocorneal endothelial (ICE) syndrome may cause refractory glaucoma due to progressive synechial closure or membrane formation at the anterior chamber angle. Filtration surgeries are often required but are associated with a higher rate of surgical failure or complications than other types of glaucoma. Herein, we report a new and effective surgical procedure for glaucoma secondary to ICE syndrome: Ex-PRESS shunt combined with ab-interno peripheral iridectomy using a small-gauge vitreous cutter.

Secondary epiretinal membranes (ERMs) can develop from various causes, including those associated with glaucoma treatments such as trabeculectomy (TLE) and EX-PRESS (EXP) insertion surgery. This study aimed to investigate the occurrence of new ERMs and changes in preexisting ERMs following TLE or EXP insertion. Between April 2018 and March 2019, 102 and 74 eyes that underwent primary and standalone TLE and EXP insertion, respectively, were evaluated.
