Limbus‐based versus fornix‐based conjunctival flap in glaucoma filtering surgery

Eighteen consecutive patients suffering from the same type of glaucoma in both eyes were treated with bilateral trabeculectomy. Surgery with both fornix-based and limbus-based flap was performed on each patient, one procedure in each eye. Pre- and postoperative intraocular pressure, morphology of the fistulation bleb, anterior chamber depth and need for additional treatment were recorded. Half a year after surgery, the fornix-based flap procedure was superior (p < 0.05) concerning high success rate, little additional therapy and good morphology of the bleb.
