Epithelial downgrowth is a rare but sight-threatening complication of intraocular surgery. While most cases present as aggressive epithelial sheets, epithelial inclusion cysts (EICs) represent a less common but clinically significant variant. We describe the first reported case of an anterior chamber EIC following trabeculectomy. A 53-year-old male with prior glaucoma surgery presented with a nonprogressive cystic lesion confirmed by anterior segment optical coherence tomography. Conservative management was pursued given the lesion’s quiescent nature. This case underscores the importance of individualized management for EICs, with surgical intervention reserved for cases demonstrating growth or functional compromise to avoid sight-threatening complications.
