[Congenital glaucoma and trabeculectomy]

The authors presents 27 cases (48 eyes) with congenital glaucoma operated with trabeculectomy. We used 3 different procedures of trabeculectomy: suture of the scleral flap in two points; by placing a silicon membrane under the scleral flap; tightly close of the scleral flap with five sutures. We concluded that the last of the procedures gave us the best results, especially when was used in the incipient stage of the disease. From this study results that the mechanism of action of trabeculectomy is more an opening of a physiological way of drainage then a filtration to the subconjunctival space.
