Painful,Large Bleb after Glaucoma Filtering Surgery

ABSTRACT

An overhanging, large bleb after filtering surgery leads to various complications ranging from foreign-body sensation to endophthalmitis. Herein we report two case of large painful blebs in nasal area. Argon laser was initially used for its shrinkage. However, this procedure was not successful, requiring surgical excision of bleb. The tissue was then examined to evaluate the cause of failure with the argon laser treatment. On examination, the bleb showed a pseudocyst, and hyaline degeneration in the inner membrane of the bleb. Shrinkage of the large bleb resulted in resolution of the pain.
