[Surgical treatment of certain forms of secondary glaucoma]
Abstract:
The technique of penetrating deep sclerectomy with suprachoroidal explanto-drainage as well as the results of postoperative follow-up, exceeding 2 years, and of the early-described sinustrabeculectomy with regulated filtration are presented in the article. Operations were made on 59 eyes (58 patients aged 13 to 70) with the below forms of secondary glaucomas: new-vascular, postuveal, dystrophic (at retinal detachment), posttraumatic (contusion-type), phakotopic, postoperative (aphakic), and hemolytic. The below goals were set while elaborating the methods: the possibility to regulate postoperatively the intraocular pressure, elimination of the pain syndrome, the organ-preserving effect, stabilization of the clinical cause and shaping-up of reliable drainage paths. The authors registered a positive effect in 87.5% of cases.
