Further observations on eccentric perilimbal suction cup application

Absence of an anemic, cystic bleb site, as well as reduced fluorescein fluorescence in this area after transcleral fistulizing surgery, infer failure. One method to create or augment bleb formation in suitable eyes is with the use of eccentric suction. This method creates localized ocular message, mobilizes conjunctiva and episclera, and provides a quantitative measure of bleb function.
