[Glaucoma surgery in childhood].

Technical characteristics and a long-term therapeutic strategy due to a long life expectancy play a key role in pediatric glaucoma surgery. The well-established angle surgery (goniotomy and trabeculotomy) achieves successful results in primary childhood glaucoma. Trabeculectomy seems to have been displaced as a secondary approach by glaucoma drainage devices (GDD) in primary childhood glaucoma due to inferior results, especially for children under 3 years of age. Even for secondary childhood glaucoma the results of GDD are encouraging, especially for therapy refractory aphakic glaucoma. In the first 2 years after GDD surgery success rates are about 80% for pediatric glaucoma and the results appear to be independent of the type of glaucoma and implant used. The complications of GDD are balanced to the faster intraocular pressure (IOP) control during the phase of visual acuity development. Cyclodestructive procedures may be applied as a secondary adjuvant approach but they increase the risk of conjunctival scarring and hypotony for subsequent procedures.
