PURPOSE: The purpose of this retrospective study is to compare the results of deep sclerectomy versus trabeculectomy for IOP reduction and the respective complication rates. METHODS: 199 patients were treated by deep sclerectomy and 80 patients by trabeculectomy between 2000 and 2005. Retrospective results for IOP reduction, visual acuity, success, complication and re-operation rates were evaluated. RESULTS: After deep sclerectomy the IOP dropped from 20.8 mmHg (± 6.5) to 23.8 % after 1 year, upon trabeculectomy from 27.7 mmHg (± 9.4) to 46.4 %. Visual acuity decreased only slightly. The success rate after a follow-up of 62.3 months (no re-operation or local post-operative treatment) was 36.7 % on treatment by deep sclerectomy compared with 56.3 % by trabeculectomy after a follow-up of 43.6 months. After 15.2 months a mean of 21.6 % of our patients who were treated by deep sclerectomy needed a re-operation, in the trabeculectomy group after 3.9 months this was the case in 17.5 %. One year after treatment by deep sclerectomy 37.2 % and after trabeculectomy 18.8 % of our patients needed glaucoma eye drops for additional local treatment. CONCLUSIONS: Both treatments (deep sclerectomy and trabeculectomy) achieve a target IOP below 18 mmHg after one year. Deep sclerectomy is in special cases an efficient alternative to trabeculectomy with the right indication (for less IOP lowering or high-risk eyes). LA: German
