Abstract Details


At is known, in some patients, in different periods after anti-glaucoma operations, relapse of IOP increase is observed. More lasting decrease of IOP (Intra Ocular Pressure) in terms of duration and level is still achieved after trabeculectomy, which has high percentage of serious sight-threatening complications. The goal of the study is evaluation of efficacy and safety of conducting repeated NDSE in patients with operated primary open-angle glaucoma.


Microsurgery department, ophthalmology, Bishkek, Kyrgyzstan


For periods 2000-2008 378 NDSE procedures in 363 patients with open-angle glaucoma were performed. PatientÂ’s age: 61.0 +/- 11.5. From which 48 (12%) of eyes with operated glaucoma. In 23 cases silicon tunnel drainage was used, in 25 cases silicon porous drainage was used, with suggested modification.


Follow up period is from 1-18 months. 1. At the time of patientÂ’s last visit, qualified success with <= 21 mm Hg achieved: -29 eyes (60%) without medication, - 19 eyes (39%) medically controlled. 2. IOP was reduced; visual acuity improved in 36 eyes (75%) and remained the same in 12 eyes (25%) 3. IOP was reduced from 24.3 +/- 3.9 mm Hg pre-operatively to 17.9 +/- 3.1 mm Hg post-operatively 4. Complications: the only major complication in 6 eyes (12%) was microperforation After the surgery in group of patients with silicon tunnel drainages IOP was reduced from 27.3 +/- 3.9 to 20.5 +/- 3.2. After the surgery in group of patients with silicon porous drainages IOP was reduced more significantly from 27.3 +/- 3.9 to 17.9 +/- 3.1.


- Despite surgery being repeated, this study could confirm efficacy and safety of repeated NDSE. - After repeated NDSE complication rate is very low. - For the purpose of increasing the efficacy of surgery we used two types of silicon drainages, porous and tunnel. Porous silicon drainage was more efficient for reduction of the IOP in terms of bf both level and duration. FINANCIAL DISCLOSURE?: No
