[Comparative results of trepanotrabeculectomy and iridencleisis in primary glaucoma].

For the last 10 years 500 iridencleisis and 250 trepanotrabeculectomies were performed. For this study are subjected only 205 cases of basal and total iridencleisis and 100 cases of trepanotrabeculectomy, performed in chronic open and chronic closed angle glaucoma. The authors point out that some common factors play the role on the final results, independently of the type of the operation. It was observed that the results were worse in patients having the diabetes and/or arterial hypertension, when the operation is performed in the advanced age or in the late stage of glaucoma, and also if the eye was already operated. To evaluate the result of the operations (basal and total iridencleisis, trepanotrabeculectomy) the authors estimate that is not enough to take the intraocular tension as the unic parameter, one should take in consideration also the visual field, visual acuity and also the state of the optic disc in the follow-up period (see Tbl. 4). This period should not be shorter than one year. With the trepanotrabeculectomy (85%) and with total iridencleisis (86,5%) the intraocular tensions could be normalised in the higher percentage than with the basal iridencleisis (75,5%). On the other hand, if one take also the other parameters for the evaluation (visual field, visual acuity, status of the optic disc) one could conclude that the best result was achieved with trepanotrabeculectomy (80% the complete consolidation), and than with total iridencleisis (69,4%) or basal iridencleisis (67%). In trepanotrabeculectomy the peroperative and postoperative complications are rare.
