[Antiglaucomatous trabeculectomy (author's transl)].

UNLABELLED

The case material covers 115 glaucoma patients in whom antiglaucomatous trabeculectomy had been performed. Observation times: between a maximum of 3 years (12 cases) and a minimum period of 6 months (18 cases).

CLASSIFICATION

Open-angle glaucoma 28 cases (22.8%), narrow-angle glaucoma 22 cases (19.1%), air-block glaucoma 17 cases (14.75%), other types 16 cases (13.91%). Best results were obtained with the open-angle glaucoma; surgery had reduced the pressure to normal in 85.21% of the cases. In addition, normal pressure was achieved by drug therapy in 8.8% of the cases. Good results were also obtained in glaucomas with narrow angle of iris (pressure normalization in 86.3% of the cases), as well as in combined surgery when glaucoma and cataract occurred simultaneously. The mechanism of action of the surgical procedure consists in the formation of a fistulating excretory duct covered up by a scleroconjunctival wall, generally forming a flat seepage cushion.
