Purpose: Conjunctival incisional surgery is a known risk factor for trabeculectomy failure. The occurrence of avascular bleb following failed ab interno XEN stent implantation has been documented in patients undergoing trabeculectomy with mitomycin C (MMC). However, reports on same quadrant trabeculectomy with MMC after failed ab externo open conjunctiva XEN stent implantation are scarce. This study sought to document the 1-year clinical outcomes and bleb morphology following this procedure.Case summary: This retrospective study reviewed the medical records of 4 eyes from 4 patients who received trabeculectomy with MMC in the same quadrant following ab externo open conjunctiva XEN stent implantation failure. At 1 year after trabeculectomy, the intraocular pressure was successfully controlled without glaucoma medication, and no visual field progression was observed. Anterior segment tomography indicated that the blebs were elevated and broad, with a suprascleral fluid-filled space evident in all eyes. There were no instances of prolonged hypotony or bleb leakage one year after the trabeculectomy, although an avascular bleb was observed in one eye. Conclusions Performing trabeculectomy with MMC in the same quadrant appears to be an effective method for reducing IOP after the failure of ab externo open conjunctiva XEN stent implantation.

Purpose: We present a case of malignant glaucoma following cataract surgery in a nanophthalmic eye.Case summary: A 74-year-old woman with a nanophthalmic right eye (axial length 20.51 mm) underwent cataract surgery at a local hospital. One week postoperatively, she presented with a dislocated intraocular lens (IOL) and a shallow anterior chamber. Malignant glaucoma was suspected, and the patient underwent pars plana vitrectomy followed by neodymium-doped yttrium aluminum garnet laser posterior capsulotomy. Despite these interventions, the IOL remained anteriorly displaced, prompting referral to our institution for further management. Upon presentation, the patient exhibited an intraocular pressure (IOP) of 38 mmHg despite maximal medical therapy; spherical equivalent (SE) was -3.88 diopters. To differentiate pupillary block and establish a definitive diagnosis, laser iridotomy was performed; this resulted in a significant reduction in IOP to 10 mmHg and deepening of the anterior chamber. However, 19 days post-iridotomy, the IOP again increased to 39 mmHg; the SE worsened to -4.88 diopters. Slit-lamp examination and ultrasound biomicroscopy revealed a transparent membrane obstructing the iridotomy site behind the iris, consistent with a complex of disrupted ciliary zonules and the anterior hyaloid. Subsequently, photodisruption of this membrane was performed through the existing iridotomy. This intervention deepened the anterior chamber and achieved a wide-open iridocorneal angle. At the last follow-up, the patient had maintained an IOP of 10 mmHg without glaucoma medication. Furthermore, SE improved to -0.38 diopters, resulting in a best-corrected visual acuity of 1.0. Conclusions Our case demonstrates the development of malignant glaucoma following cataract surgery and subsequent total vitrectomy and laser posterior capsulotomy in a nanophthalmic eye. Thorough irido-zonulo-hyaloidotomy demonstrated to be an effective approach for achieving significant IOP reduction.

Purpose: To report a case of angle-closure glaucoma caused by pupillary block in a patient with familial exudative vitreoretinopathy (FEVR).Case summary: A 20-year-old man with FEVR presented with sudden-onset pain in his left eye. The best-corrected visual acuity (BCVA) was 0.04, and the intraocular pressure (IOP) was 76 mmHg. The central anterior chamber depth was reduced to twice the corneal thickness. Gonioscopy revealed 360° angle closure. Anterior segment optical coherence tomography and ultrasound biomicroscopy demonstrated a closed angle and anteriorly convex peripheral iris due to forward displacement of the lens–iris diaphragm and contact between the iris and lens. Trabeculectomy and cataract surgery were performed because the IOP was not controlled despite maximal medical therapy. At 9 months postoperatively, the IOP was 13 mmHg without the use of glaucoma medications, and the BCVA was 0.1. Conclusions In patients with FEVR, angle-closure glaucoma due to pupillary block can occur even at a young age. FEVR should be considered in young patients with acute angle-closure glaucoma.

This study aimed to assess the prognostic role of body mass index (BMI) in patients with metastatic renal cell carcinoma (mRCC) treated with first-line immune checkpoint inhibitor (ICI)-based therapy. We searched for relevant studies in the MEDLINE, Embase, and Cochrane Library databases. The initial search yielded 599 records, of which seven articles (2,517 patients) were selected for analysis. Patients with a high BMI had a favorable overall survival (OS) based on hazard ratio (HR) (crude HR 0.69, 95% confidence interval [CI] 0.57–0.83, p<0.0001; adjusted (a)HR 0.75, 95% CI 0.59–0.95, p=0.02), but not relative risk (RR 0.88, 95% CI 0.67–1.16, p=0.37). In the subgroup analysis, patients with a high BMI had better OS in the ICI with tyrosine kinase inhibitor (TKI) subgroup (aHR 0.71, 95% CI 0.55–0.92, p=0.01), while no significant difference was found in the ICI-only subgroup (aHR 1.02, 95% CI 0.56–1.87, p=0.95). Adjusted statistics for progression-free survival (PFS) were assessable in predominantly ICI-only studies and demonstrated a favorable outcome for patients with a low BMI (aHR 1.67, 95% CI 1.14–2.45, p=0.01). In conclusion, the impact of high BMI varies depending on the treatment type, exhibiting a favorable correlation with OS within ICI with TKI subgroup, but indicating an adverse association with PFS in the ICI-only subgroup. Further research is needed to clarify the influence of BMI by stratifying patients into ICI-only and ICI with TKI treatment to provide more insights.
