Previous reports from the Freiburg Eye Clinic concerning surgical techniques and experiences with iris sutures are complemented by this description of long-term follow-ups (up to 8 years, 6 1/2 years on average) of a random selection of 65 eye which underwent surgery. There were no harmful reactions to the suture of the suture material (nylon, 30 micrometers). Three-fourths of the eyes examined presented with tissue bridges, indicating fibroblastic unification of the sutured tissues. Even where there was preoperative atrophy of the connected iris parts (following glaucoma attacks with iris infarction) the connection remained stable over the years. These long-term follow-up findings support earlier recommendations concerning indication and surgical technique.
