The authors evaluated efficiency of antiglaucomatous surgery in 73 eyes of 50 children, staying under clinical control in the years 1969-1991. It was showed that after trabeculectomy, as the primary procedure, intraocular pressure was normalized much more often (40.9%) than after goniotomy (20.2%). In cases operated many times using different technics, more effective was goniotomy. Better visual acuity was found in cases with intraocular pressure well controlled after one surgical procedure. The most common complications connected with surgery were discussed.
