Mucogenic glaucoma and goblet cell cyst of the anterior chamber.

A 25-year-old woman had a unilateral open-angle glaucoma that was initially thought to be caused by an anterior uveitis. A deformity of the chamber angle was noted and interpreted as a peripheral anterior synechia or an old scar. A peculiar haze was noted in the anterior chamber. The intraocular pressure was controlled by trabeculectomy. A slowly enlarging cyst was observed at the site of a previous anterior synechia. Excision of the cyst resulted in clearing of the anterior chamber haze. The second trabeculectomy specimen contained mucous strands. Problems exist, both clinically and histopathologically, in diagnosing and managing this rare form of secondary glaucoma (mucogenic glaucoma).
