Supplementary Material for: Occult Uveitis-Glaucoma-Hyphema Syndrome Caused by PCIOL with Peripheral Capsular Tear

Uveitis-glaucoma-hyphema (UGH) syndrome is an infrequent but severe complication following intraocular lens (IOL) implantation, characterized by anterior chamber inflammation and elevated intraocular pressure (IOP). This report presents a rare case of late-onset UGH syndrome induced by a well-positioned 1-piece posterior capsular intraocular lens (PCIOL) with a bulb of the haptic extruding through a peripheral capsular tear in a 90-year-old female, 17 years post-cataract surgery. The patient presented with persistent blurred vision, recurrent anterior uveitis, and uncontrolled IOP despite medical therapy. Extensive evaluation, including ultrasound biomicroscopy, failed to identify the underlying cause, necessitating surgical intervention to control IOP. During concurrent goniotomy and canaloplasty, a PCIOL haptic was discovered protruding through a peripheral capsular tear, establishing the diagnosis. Following PCIOL-haptic amputation and goniotomy and canaloplasty, the patient experienced significant improvement in symptoms and IOP control, with complete resolution of UGH syndrome. This case highlights the necessity of considering atypical causes in persistent postoperative uveitis and IOP elevation and emphasizes the role of surgical intervention in managing complex cases.
