A major focus of our study was the ability to predict the long-term success of filtering surgery. The results of @entity726 filtering surgery (trabeculectomy) as performed by the staff of the University Eye Hospital of T  bingen from 1988 through 1994 on 254 eyes of 214 @entity1 are presented, with particular emphasis being placed not only on intraocular pressure (IOP) control but also the progression of @entity16 ( @entity227 or disc damage) and the etiology of visual acuity losses. There was an overall success rate of 64%. Rigid criteria for success included an IOP of less than 30 mmHg, no further @entity227 or disc damage, and no glaucomatous etiology for a decrease in visual acuity. A total of 35 eyes (13.8%) showed a @entity227 after 6 months amounting to 2 or more Snellen lines, caused mainly by lens opacification, @entity8814 @entity1020 , and "wipeout" (loss of the central visual field in the absence of another explanation). We found that there is a considerable risk for @entity227 after operation on older @entity1 with small residual visual fields and severe @entity8814 on the 1st postoperative day. There was a 13% incidence of @entity177 . A total of 34 eyes had an early IOP rise of more than 30 mmHg after surgery. A @entity86 of less than 3 mmHg was more significantly seen in @entity1 treated with @entity1487 . Moreover, the results show that in some instances, a long-term use of topically applied @entity726 medication can adversely affect the results of fistulizing surgery.(ABSTRACT TRUNCATED AT 250 WORDS)
