[Quantitative trabeculectomy]

The outcomes of the trabeculectomy which finally establish one normal ocular pressure are presented. The surgery method is adjustment of the thickness of the sclera, fragment depending on the initial ocular pressure. The evacuation of the aqueous humor after trabeculectomy is indirect proportionally with the thickness of the scleral fragment. The method was used in 36 eyes with different patterns of glaucoma. At this patients the initial ocular pressure was until 50 mm Hg. In 72.2% from cases was necessary only one surgery intervention for maintain the ocular pressure, without auxiliary drugs; two eyes underwent still one surgical intervention and in seven eyes was necessary auxiliary hypotensor drugs. The outcomes were good in 97.2% from cases. One failure was obtained in one eye with closed angle glaucoma where the trabeculectomy was complicated with malignant glaucoma. Complications were hypema, atalamy with or without choroidal detachment and high ocular pressure. All complications were improved after conservative treatment excepting the case with malignant glaucoma.
