Bleb-limiting conjunctivoplasty for symptomatic circumferential trabeculectomy blebs.
OBJECTIVE
To describe a new surgical technique for limiting symptomatic circumferential conjunctival blebs, an uncommon complication after trabeculectomy.


METHODS
Four eyes of 2 patients underwent conjunctivoplasty to limit the extent of symptomatic circumferential blebs. An 8/0 virgin silk corneal traction suture was used to allow better exposure of the conjunctiva. Radial conjunctival and Tenon incisions were made down to bare sclera in approximately the 10:30 and 1:30 clock hour positions. The conjunctival incisions were sutured, tacking down to the sclera.


RESULTS
Immediate flattening of the interpalpebral bulbar conjunctiva was noted on the first postoperative day and there was no elevation of intraocular pressure or loss of bleb function. Both patients experienced a rapid improvement in their symptoms and no complications of the procedure were noted. Recurrence of bleb extension occurred in 1 eye 4 months postoperatively, and was treated with a repeat limiting conjunctivoplasty incision with a good result.


CONCLUSIONS
Early results show that bleb-limiting conjunctivoplasty is an effective means of treating symptomatic circumferential trabeculectomy blebs.
