Conjunctival retraction with deposits after trabeculectomy.

Purpose: To describe a case of late-onset conjunctival flap retraction after fornix-based trabeculectomy, presenting with chronic subconjunctival accumulation of yellow crystalline material, which responded to antifungal and broad-spectrum antibiotic therapy. Observation: A 26-year-old female patient with a history of congenital glaucoma underwent combined trabeculotomy and fornix-based trabeculectomy in the left eye at 4 months of age. Over the years, the patient experienced recurrent episodes of redness, responding to topical antibiotics. Two months prior to presentation, the patient developed persistent ocular redness and yellow discharge in the left eye. Examination revealed conjunctival hyperemia, conjunctival flap retraction with sub-conjunctival yellow crystalline deposits, and suture debris. Microbiological testing of the conjunctival sac contents identified fungal ( Conclusions and importance: Complications of trabeculectomy-related conjunctival flap have most commonly been reported as conjunctival flap fibrosis and infection. We present a rare case of conjunctival flap retraction leading to the formation of a subconjunctival cavity with crystalline deposits, complicated by chronic fungal infection.
