Infectious endophthalmitis after ocular surgery is a rare complication that can result in severe vision loss. Moraxella nonliquefaciens is an opportunistic pathogen that rarely causes ocular infections. We report a rare case of Moraxella nonliquefaciens endophthalmitis complicated by secondary angle-closure glaucoma occurring years after trabeculectomy and cataract surgery. Cycloplegia resulted in deepening of the anterior chamber and opening of the angles. Metagenomic next-generation sequencing of the aqueous humor identified Moraxella nonliquefaciens . Following multiple intravitreal vancomycin injections and vitrectomy with posterior capsulectomy, direct communication between the anterior chamber and the vitreous cavity was established, leading to resolution of the condition. The patient’s visual acuity was fully restored. We hypothesize that persistent infection with Moraxella nonliquefaciens may damage the lens zonules, resulting in zonular laxity and weakness; however, this represents only one possible mechanistic explanation and may play a secondary role in the development of secondary angle-closure glaucoma. Ophthalmologists should be aware that patients with Moraxella nonliquefaciens endophthalmitis may be at risk of zonular laxity and secondary angle-closure glaucoma, particularly years after trabeculectomy and cataract surgery. Prompt recognition and intervention may be vision-saving.
