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.

Experience with trepanotrabeculectomy.

The authors analysed the effect of 100 trepanotrabeculectomy operations performed in primary (79 cases), in congenital (16 cases) and in secondary (5 cases) types of glaucoma. The operation itself could normalize the intraocular pressure in 87% of the cases, in 8% the intraocular pressure was normalized by miotics after the operation. In 3% of the cases the pressure could not be controlled even by the additional application of miotics and in 2% of the cases the operation produced a hypotony. The intraoperative and postoperative complications were temporary and without definitive sequels. As the blebs were present in 76% of cases, the authors concluded that the drainage took place under the scleral and conjunctival flap. In the smaller group, the blebs were absent but the intraocular tension was normalized. In these cases it is supposed that Schlemm's canal represents the main route of drainage. According to the authors' experience, trapanotrabeculectomy represents an operation which is easy to perform, which can not cause severe operative or postoperative complications and which can achieve normalization of the intraocular pressure, either by itself or with miotics, in a high percentage of cases.
