Management of persistent filtering cicatrix following cataract extraction

H. G. Scheie, E. Pitts and F. J. Martin

We used a safe and simple surgical technique in the management of persistent filtering cicatrices after cataract extraction. The edematous, friable filtering cicatrix was excised entirely and a healthy fornix-based conjunctival flap was sutured over the fistula. Invariably, the fistula was very small, usually only large enough to admit a 27-gauge needle. Of the 27 eyes treated with this technique, there were two failures, but no other complications.
