Limbus-based versus Fornix-based conjunctival flap in filtering surgery. A randomized prospective study

Int Ophthalmol. 1989 Jan;13(1-2):139-43. doi: 10.1007/BF02028654.


A randomized prospective study was performed to compare the results of filtering surgery using a Limbus-based versus a Fornix-based conjunctival flap. The wound closure of the Fornix-based flap was performed using a running 10/0 nylon suture at the limbus. No statistical significant difference of IOP regulation was found between the two groups. There was a tendency of reduced occurrence of shallow anterior chamber and of less vascularized filtering blebs in the Fornix-based technique.
