Preoperative clinical examinations and results of trabeculectomy two years after the operation
Hornova JČeska a Slovenska Oftalmologie 2003; 59: 257-263
PURPOSE: To determine whether preoperative anatomical and functional results have an influence on the postoperative decreas in intraocular pressure (IOP) and therapy two years after trabeculectomy (TE). METHODS:: In a retrospective study 40 patients (80 eyes) with primary open angle glaucoma were followed. They underwent TE with two releasable sutures on both eyes performed by the same method and the same surgeon. The preoperative and postoperative levels of IOP (as measured by the Goldmann tonometer) and therapy (according to target pressure) were compared with preoperative gonioscopy (Shaffer's scale 0-4), the excavation of the optic nerve (c/d ratio) and preoperative results of the visual field (threshold tests and Aulhorn's classification 0-V). RESULTS: The preoperative size of the angle of the anterior chamber has no expressive influence on the postoperative decreas in IOP (p = 0.079), there is an even smaller influence on decreas on therapy (p = 0.619). As well the preoperative excavation of the optic disc had no influence on the postoperative decrease in IOP (p = 0.179) and therapy (p = 0.467). There is an analogy with the visual fields; preoperative changes had no influence on the postoperative decrease IOP (p = 0.502) and therapy (p = 0.247). CONCLUSION: Preoperative anatomical and functional status had no the influence on the success of TE. LA: Czech
