[Non-perforating deep sclerectomy ab externo with intrascleral implant in juvenile glaucoma]

Abstract

Purpose: Trabeculectomy, a very well known procedure giving mainly good result, may sometimes produce many serious postoperative complications, connected with opening of anterior chamber. Another operating technique prepared by Fyodorov, Zimmerman and Kozlov, seems to be useful in all cases with open-angle glaucoma and does not produce complications like the once caused by trabeculectomy.

Material and method: Non-perforating sclerectomy was performed on 7 children aged 8 to 15 with juvenile glaucoma /in 4 cases as the first procedure and in 3 cases as a secondary technique after trabeculectomy done more than 10 years before/. The operative technique was done with an implant to sclera made from natrium sodium of hialuronic acid. Observation lasted from 6 to 18 months.

Results: In 6 cases good results were obtained after the first procedure, in one reoperation was necessary. The intraocular pressure /less than 20 mmHg/ was low in all eyes during 6 months observation, after a year low intraocular pressure decreased in 72% of cases, but with complimentary local therapy was low in all cases. In 1 eye there was intraoperative complication-perforating of Schlemm's canal structures but without great outflow of aqueous. All parameters of vision /visual acuity and visual field/ were stable.

Conclusions: This operative technique, although difficult to perform was not dangerous for the eye and gave good results, unfortunately only in some of the eyes.
