[Early atrophy of the conjunctiva after trabeculectomy with mitomycin C and collagen matrix implant].

Complete atrophy of the filtration bleb is a very rare complication after trabeculectomy with mitomycin C and collagen matrix implant (Ologen®, Aeon Astron Corporation, Taipei, Taiwan). Clinically, the atrophy can present similar to blebitis. We report the case of a 71-year-old woman, in whom we resected the atrophic conjunctiva and reconstructed a filtration bleb using an amniotic membrane.
