[Goniotrepanation with Triangular Scleral Flap (author's transl)].
In order to obtain a more permanent regulation of I.O.P. the size of the usual 20 mm2 scleral flap is reduced by about one half. Instead of the quadrangular scleral flap a lamellar triangular flap of 5 mm side length is prepared. This corresponds with a surface area of ca.10 mm2. The reduction of the scleral flap and accordingly the scleral wound does not lead to any disadvantages as compared to the method of Fronimopoulos. The advantages, however, are a significant shortening of the filtration path with less scarring tendency and a simpler way of preparing the scleral flap. Also in the combination of cataract and glaucoma operations the triangular scleral flap was found to be useful.
