Fibrin Pupillary-block Glaucoma after Uneventful Phacovitrectomy in a Patient with Proliferative Diabetic Retinopathy (PDR): A Case Report
Main Article Content
บทคัดย่อ
Background: Fibrin pupillary-block glaucoma is an uncommon complication after phacoemulsification or vitrectomy. Various treatment modalities relieving fibrin pupillary-block have been reported, such as intracameral recombinant tissue plasminogen activator (rTPA), argon–neodymium: YAG (Nd:YAG) laser iridotomy, Nd:YAG laser membranotomy, and medical dilation.
Objective: To report a patient with proliferative diabetic retinopathy (PDR) who developed fibrin pupillary-block glaucoma after uneventful phacovitrectomy and was successfully treated with Nd:YAG laser membranotomy.
Methods: Retrospective case report.
Results: The patient was a 59-year-old Thai male with PDR, epiretinal membrane and tractional macular edema in his left eye. Combined phacoemulsification with pars plana vitrectomy (PPV) was performed. On postoperative day 7, the patient presented with blurred vision from corneal microcystic epithelial edema associated intraocular pressure (IOP) spike due to the presence of fibrin membrane obstructing the pupil opening and was diagnosed with fibrin pupillary-block glaucoma. Nd:YAG laser membranotomy was performed and resulted in complete resolution of pupillary block.
Conclusion:Laser Nd:YAG membranotomy provides safe and effective resolution of fibrin pupillary-block glaucom.
