[Long-term results of congenital glaucoma microsurgery--retrospective study]

Medium and long term results of trabeculotomy and goniotomy operations for primary congenital glaucomas treated in Lausanne between 1965 and 1990 were studied retrospectively. Parameters evaluated were intraocular pressure (IOP) and final visual acuity (VA). Data on IOP were available for 38 eyes. 66% underwent trabeculotomy and/or goniotomy (first group) the others needed further surgical or medical treatment (second group). IOP was equal or inferior to 19 mmHg in 88% of the first group and 62% of the second group at the end of the study (mean follow-up 13.1 years). Data on VA were available for 32 eyes. In the first group, 65% showed a VA of more than 0.5 compared to 33% for the second group. Therefore, we can consider trabeculotomy and goniotomy as early operations as advisable in first intention treatment of primary congenital glaucoma.
