Purpose: To report three cases of bleb-related endophthalmitis (BRE) treated with endoscope-assisted vitrectomy and to describe the surgical approach and clinical outcomes. Methods: We retrospectively reviewed three patients who developed BRE after glaucoma filtering surgery. All patients underwent pars plana vitrectomy (PPV) combined with endoscopic guidance using a 25-gauge endoscope, removal of avascular filtering blebs. Intraoperative findings, postoperative courses, and visual outcomes were evaluated. Results: Endoscope-assisted vitrectomy enabled visualization of the peripheral vitreous despite corneal edema. In all cases, the infection resolved without recurrence. Postoperative visual acuity improved and exceeded previously reported averages. In one case, endoscopy revealed peripheral retinal degeneration, which was treated intraoperatively with laser photocoagulation, thereby preventing retinal detachment. Conclusions: Endoscope-assisted vitrectomy may be a useful surgical approach for treating BRE, particularly in cases complicated by corneal edema. The technique allows precise peripheral vitreous removal and facilitates early identification of retinal pathology.
