A 59-year-old man with diabetic macular oedema was treated with a dexamethasone intravitreal implant (Ozurdex) to his right eye. Immediately after injection, the implant was noted to have extruded into the perilimbal subconjunctival space. The remnants of the implant were expeditiously removed the following day to avoid corneal decompensation and permanent corneal oedema. Endothelial decompensation secondary to the migration of dexamethasone implants into the subconjunctival space or anterior chamber is a recognised complication of Ozurdex injection. The patient recovered well postoperatively with no further complications. He was planned for a new Ozurdex implant 1 month later.
Background:The main objectives of this study were to determine whether known risk factors for trabeculectomy failure similarly influence gelatin stent outcomes and to identify surgical factors which may optimise success.Methods: A retrospective, observational study was conducted at a single centre in Perth, Western Australia over 24 months. Two-hundred and sixty-two eyes of 207 patients underwent XEN-45 stent surgery with various forms of glaucoma.Surgical and postoperative data on subjects undergoing XEN-45 stent surgery was collated. Intraocular pressure (IOP) reduction success was determined using three criteria: 1; IOP <18 mm Hg, 2: IOP <15 mm Hg and 3: >25% IOP reduction from baseline. Kaplan-Meier, mixed effects Cox Proportional hazard model and Chi-Square test were used to measure survival of functioning stents. Results:The success rates at a maximum of 2 years after surgery by criteria 1, 2 and 3 were 61.3%, 26.2% and 28.9% in primary open angle glaucoma (n = 243), 18.8%, 16.9%, 21.4% in angle closure glaucoma (n = 11), 0%, 0%, 66.7% in congenital glaucoma (n = 5) and 0% in uveitic glaucoma (n = 3). No significant reduction in success was found in those eyes that had prior ocular surgery (all p > 0.07).
Purpose: To report a case of Epstein-Barr virus (EBV) uveitis after intravitreal triamcinolone injection. Methods: Observational case report. Results: A 66-year-old male presented with bilateral intermediate uveitis, left macular branch retinal vein occlusion, and left macular edema 3 months following acute infectious mononucleosis. He received systemic prednisolone, methotrexate, and intravitreal bevacizumab with partial response. Intravitreal triamcinolone was given for recurrent macular edema, which led to the development of severe panuveitis with positive EBV PCR in aqueous humour. This was successfully treated with high-dose systemic valaciclovir and topical prednisolone. Conclusion: Non-infectious uveitis may become infectious following intravitreal steroid administration triggering intraocular viral replication. Intraocular fluid should be tested in cases which are suspicious for infection and EBV should be considered a differential diagnosis, particularly if PCR is negative for more common viral etiologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
