Purpose: to compare the efficacy and safety of Ahmed and Molteno-3 drainage devices implantation in the surgical treatment of refractory glaucoma. Patients and methods. Two groups of refractory glaucoma patients underwent surgery. In the first group (48 patients, 48 eyes) drainage device Molteno-3 with a site size of 175 mm2 was implanted. The average IOP in the group before surgery was 31.9 ± 7.7 mm Hg. The average number of glaucoma medications was 3.3 ± 0,44. In the second group (51 patients, 51 eyes) implantation of Ahmed Valve FP7 model was performed. The average level of IOP in the group before surgery was 34.7 ± 8.07 mm Hg. The average number of glaucoma medications was 3.08 ± 0.4. Results. In the first group the average intraocular pressure level 1 month post-op was 14.6 ± 6.1 mm Hg, 3 months post-op 18.8 ± 5.2 mm Hg, 6 months post-op 16.5 ± 4.7 mm Hg. IOP сompensation (≤ 21 mm Hg) in 6 months was achieved in 91.6 % of cases and in 1 year in 100 % of cases. The total success was achieved only in 8.3 % of patients. However, the number of glaucoma medications was reduced to 1.6 ± 0.8. In the second group the average IOP level 1 month post-op was 21.25 ± 7.3 mm Hg, 3 months post-op 17.9 ± 5.3 mm Hg, 6 months post-op 15.7 ± 4.1 mm Hg. IOP сompensation in 6 months was achieved in 82.4 % of cases and in 1 year in 86.3 %. In the second group complete success was achieved in 19.6 % of patients. The number of glaucoma medications was 1.4 ± 1.1. In the first group complications were revealed in 22.9 % of cases (11 patients). Ciliochoroid detachment was revealed in 9 patients (18,8 %) and hyphema in 2 patients (4,2 %). In the second group complications were revealed in 19.6 % of cases (10 patients). Сiliochoroid detachment was revealed in 4 patients (7.8 %), diplopia in 5 patients (9.8 %), hyphema was detected in one case (1.9 %). In the first group IOP compensation (≤21 mm Hg) was achieved after 6 months in 91.6 % of cases and after 1 year in 100 % of cases. The complete success was achieved in only 8.3 %. In the second group, IOP compensation in 6 months was achieved in 82.4 % of cases and 86.3 % — in 1 year. In the second group, complete success was achieved in 19.6 % patients. There was no significant difference in complications between two groups. Conclusion. High level of safety and effectiveness of refractory glaucoma surgical treatment with implantation of Molteno-3 and Ahmed drains was confirmed.

Purpose To describe a case series of combined 23-gauge vitrectomy and pars plana Baerveldt tube insertion for intraocular pressure (IOP) control in eyes with glaucoma resistant to maximum tolerated medical therapy and/or having failed previous IOP-lowering procedures. Methods Eight consecutive patients (8 eyes) undergoing a combined procedure were identified and included in this study. Outcome measures included preoperative and final best-corrected visual acuity (VA), IOP, number of glaucoma medications, and complications. Changes in IOP and glaucoma medications were compared by a paired t test. A Kaplan-Meier survival curve was constructed to evaluate IOP control as a function of time. Results Mean patient age was 70.9 years while the mean follow-up time was 12.1 months. Open angle glaucoma was diagnosed in 5 (68%) eyes. Six (75%) eyes were pseudophakic. All eyes received a 250-mm2 pars plana Baerveldt tube. Vision remained the same or improved in 6 (75%) eyes. Mean preoperative IOP and number of glaucoma medications were significantly (p<0.05) reduced by the combined procedure. Visual acuity of 5 (63%) eyes improved or remained unchanged. Six (75%) eyes encountered minor complications not requiring a return to the operating room. One (13%) eye underwent drainage of hemorrhagic choroidals on postoperative day 12. Conclusions A combined 23-gauge vitrectomy and pars plana Baerveldt tube insertion could be considered a useful procedure in reducing IOP and the number of glaucoma medications in eyes with refractory glaucoma.

Purpose: To evaluate clinical efficacy and safety of single Ultrasound Cyclo-Plasty (UCP) in the treatment of advanced refractory glaucoma. Methods: From January 2018 to August 2018, 25 patients (25 eyes) with refractory glaucoma and intraocular pressure (IOP) not controlled by drugs or conventional filtering surgery were included in the study. All subjects (neovascular glaucoma [ n = 12], secondary glaucoma [ n = 6], angle closure glaucoma [ n = 6], and primary open angle glaucoma [ n = 1]) underwent 8-sector Ultrasound Cyclo-Plasty. Patients were followed-up at Day 1, Week 1, and at 1, 3, 6, and 12 months, during which the IOP, the number of IOP lowering drugs and the occurrence of ocular complications were recorded. Clinical outcomes were IOP reduction, success rate, and ocular complications. According to the glaucoma type, patients were divided into a neovascular group (NVG) and a non-NVG group for sub-analysis. Results: All patients underwent a single UCP procedure and mean IOP reduced significantly from 39.7 ± 6.1 mmHg before UCP to 27.1 ± 11.0 mmHg at 1 year ( p < 0.01) corresponding to a mean IOP reduction of 29.6%. The mean number of IOP-lowering drugs used was 2.4 ± 1.2 at baseline and 2.3 ± 1.0 at 12 months. Success rate after a single UCP procedure was achieved in 41.7% patients at 1 year, with a higher success rate in non-NVG than in the NVG group. No major postoperative complications were reported. The main complication was conjunctival congestion, anterior chamber inflammation, scleral ring congestion, and scleral inprint. Of these, scleral ring congestion and scleral imprint are relatively rare complications, which can still be observed 12 months after UCP treatment. Conclusion: UCP for refractory glaucoma is effective in reducing IOP and has a good safety profile. Success rate is lower after a single UCP in NVG than for other types of glaucoma.

Purpose: To describe a visually evoked potential (VEP) examination performed on a patient with a keratoprosthesis. Methods: We report the case of a 60-year-old patient with a Fyodorov-Zuev keratoprosthesis in the right eye complained of gradual visual deterioration in that eye. His past medical history consisted of failed corneal graft procedures due to corneal dystrophy and an Ahmed valve implantation due to secondary glaucoma. A clinical examination and an ultrasound demonstrated vitreal opacities. In order to assess the visual status, a flash VEP test was conducted. Results: VEP recorded from the right eye consisted of a broadened and poorly formed positive P1 wave, with a subnormal amplitude, but a normal latency. Consequently, the patient underwent a pars plana vitrectomy. Conclusion: This case demonstrates the viability of VEP exams in patients with keratoprostheses.
