Posterior synechiae after Nd:YAG laser iridotomy: a clinical study

Methods: In 146 eyes/patients who unterwent Nd:YAG laser iridotomy after glaucomatous attack or after prophylactic iridotomy, we evaluated whether the frequency of posterior synechiae depends on (1) glaucomatous attack, (2) preoperative miotic therapy, (3) postoperative antiglaucomatous therapy or (4) mode of intraoperative laser therapy. Out of 616 eyes with YAG iridotomy between 1983 and 1987, 146 eyes/patients fulfilled the inclusion criteria: observation time of minimum 3 months after iridotomy, preoperative examination without signs of preexisting synechiae, postoperative examination at discharge and a later control examination in mydriasis to exclude posterior synechiae.
