  abstract  = {Purpose: To assess the outcomes of pars plana vitrectomy for the treatment of malignant glaucoma in patients with and without previous filtration surgery. Patients and methods: Data of 15 patients developing malignant glaucoma after trabeculectomy (60\%) or following ophthalmic interventions other than filtration surgery (40\%) were recorded retrospectively. Pars plana vitrectomy was performed in case of failed medical or laser treatment recreating the normal pathway of aqueous humor. The main outcome measures were the postoperative intraocular pressure (IOP), the frequency of complications, and success rate based on the following criteria: IOP reduction by \$20\% and to \#21 mmHg (definition one) or an IOP , 18 mmHg (definition two) with (qualified success) and without (complete success) glaucoma medication. Results: Vitrectomy reduced IOP from baseline in eyes with and without previous trabeculectomy during a median follow-up of 16.4 months (range 7 days to 58 months); although the majority of patients required glaucoma medication to reach desired IOP. The complete success rates were 11\% (both definitions) for patients with filtering blebs and none of the patients without previous trabeculectomy had complete success at the 12-month visit. Complications were few and included transient shallowing of the anterior chamber, choroidal detachment, corneal decompensation, filtering bleb failure, and need for further IOP-lowering procedures. Conclusion: Pars plana vitrectomy is equally effective for malignant glaucoma caused by trabeculectomy or interventions other than filtration surgery, although IOP-lowering medication is necessary in nearly all cases to maintain target IOP.},

  abstract  = {Background Cataract and glaucoma are both common comorbidities among older patients. Combining glaucoma surgery with minimal invasive phacoemulsification (phaco) is a considerable option to treat both conditions at the same time, although the combination with filtration surgery can produce a strong inflammatory response. Combined non-penetrating procedures like canaloplasty have shown to reduce intraocular pressure (IOP) comparable to trabeculectomy without the risk of serious bleb-related complications. The purpose of this retrospective study was to compare the outcomes of phacotrabeculectomy and phacocanaloplasty. Methods Thirty-nine eyes with concomitant cataract and glaucoma who underwent phacotrabeculectomy (n = 20; 51.3\%) or phacocanaloplasty (n = 19; 48.7\%) were included into this trial on reduction of IOP, use of medication, success rate, incidence of complications and postsurgical interventions. Complete success was defined as IOP reduction by 30\% or more and to 21 mmHg or less (definition 1a) or IOP to less than 18 mmHg (definition 2a) without glaucoma medication. Results Over a 12-month follow-up, baseline IOP significantly decreased from 30.0 ± 5.3 mmHg with a mean of 2.5 ± 1.2 glaucoma medications to 11.7 ± 3.5 mmHg with a mean of 0.2 ± 0.4 medications in eyes with phacotrabeculectomy (P < .0001). Eyes with phacocanaloplasty had a preoperative IOP of 28.3 ± 4.1 mmHg and were on 2.8 ± 1.1 IOP-lowering drugs. At 12 months, IOP significantly decreased to 12.6 ± 2.1 mmHg and less glaucoma medications were necessary (mean 1.0 ± 1.5 topical medications; P < .05). 15 patients (78.9\%) with phacotrabeculectomy and 9 patients (60.0\%) in the phacocanaloplasty group showed complete success according to definition 1 and 2 after 1 year (P = .276). Postsurgical complications were seen in 7 patients (36.8\%) of the phacocanaloplasty group which included intraoperative macroperforation of the trabeculo-Descemet membrane (5.3\%), hyphema (21.1\%) and bleb formation (10.5\%). Although more complications were observed in the phacotrabeculectomy group, no statistically significant difference was found. Conclusions Phacocanaloplasty offers a new alternative to phacotrabeculectomy for treatment of concomitant glaucoma and cataract, although phacotrabeculectomy yielded in better results in terms of IOP maintained without glaucoma medications.},

  abstract  = {Ziel Ziel dieser Studie war es, die 2‑Jahres-Ergebnisse der filtrierenden Trabekulotomie (FTO) im Vergleich zur konventionellen Trabekulektomie (TE) bei prim{\"a}rem Offenwinkelglaukom, Pseudoexfoliationsglaukom und Pigmentglaukom zu untersuchen. Patienten und Methoden Es wurden 30 konsekutive Patienten nach FTO und 87 Patienten nach TE nach intraokularem Druck (IOD) und Alter im Verh{\"a}ltnis 1:3 gematcht. Prim{\"a}rer Endpunkt war das Erreichen des Zieldrucks nach 2 Jahren. Als vollst{\"a}ndiger Erfolg wurde ein IOD ohne Medikamente von ≤ 18 mm Hg bei gleichzeitiger IOD-Reduktion um ≥ 30 \% definiert, als qualifizierter Erfolg, wenn hierf{\"u}r zus{\"a}tzlich Medikamente erforderlich waren. Sekund{\"a}re Endpunkte waren mittlere Drucksenkung, resultierende Sehsch{\"a}rfe, Komplikationen und nachfolgende Operationen. Die Operationstechnik der filtrierenden Trabekulotomie ist als Video zu diesem Beitrag abrufbar. Ergebnisse Zwei-Jahres-Daten konnten von 27 Patienten aus der FTO-Gruppe und 68 Patienten aus der TE-Gruppe erhoben werden. Die Patienten beider Gruppen wurden vor Beginn der Studie bez{\"u}glich Alter und IOD gematcht, waren aber auch bez{\"u}glich Sehsch{\"a}rfe, Geschlecht und Medikation nicht unterschiedlich. Der Median des pr{\"a}operativen IOD unter Therapie betrug in beiden Gruppen 23,0 mm Hg. Nach den oben genannten Kriterien wurde ein qualifizierter 2‑Jahres-Erfolg bei 70,4 \% der FTO-Gruppe und bei 77,6 \% der TE-Gruppe erzielt (p = 0,60), ein vollst{\"a}ndiger 2‑Jahres-Erfolg bei 33,3 \% der FTO-Gruppe und bei 56,7 \% der TE-Gruppe (p = 0,07). Beide Operationsmethoden senkten den Augeninnendruck nach 24 Monaten signifikant (p < 0,001), und zwar auf 12,8 mm Hg in der FTO-Gruppe und 11,0 mm Hg in der TE-Gruppe. Die Sehsch{\"a}rfe war postoperativ bei beiden Gruppen etwas verringert, unterschied sich jedoch nicht signifikant zwischen beiden Gruppen. Komplikations- und Reoperationsrate waren gering und unterschieden sich nicht zwischen den Gruppen. Schlussfolgerung FTO und TE sind nach 2 Jahren weitgehend gleichwertig bez{\"u}glich Zieldruck, IOD-Senkung, Sehsch{\"a}rfe und Komplikationen.},

  abstract  = {Purpose: To compare the outcomes of canaloplasty and trabeculectomy in open-angle glaucoma. Methods: This prospective, randomized clinical trial included 62 patients who randomly received trabeculectomy (n = 32) or canaloplasty (n = 30) and were followed up prospectively for 2 years. Primary endpoint was complete (without medication) and qualified success (with or without medication) defined as an intraocular pressure (IOP) of ≤18 mmHg (definition 1) or IOP ≤21 mmHg and ≥20\% IOP reduction (definition 2), IOP ≥5 mmHg, no vision loss and no further glaucoma surgery. Secondary endpoints were the absolute IOP reduction, visual acuity, medication, complications and second surgeries. Results: Surgical treatment significantly reduced IOP in both groups (p < 0.001). Complete success was achieved in 74.2\% and 39.1\% (definition 1, p = 0.01), and 67.7\% and 39.1\% (definition 2, p = 0.04) after 2 years in the trabeculectomy and canaloplasty group, respectively. Mean absolute IOP reduction was 10.8 ± 6.9 mmHg in the trabeculectomy and 9.3 ± 5.7 mmHg in the canaloplasty group after 2 years (p = 0.47). Mean IOP was 11.5 ± 3.4 mmHg in the trabeculectomy and 14.4 ± 4.2 mmHg in the canaloplasty group after 2 years. Following trabeculectomy, complications were more frequent including hypotony (37.5\%), choroidal detachment (12.5\%) and elevated IOP (25.0\%). Conclusions: Trabeculectomy is associated with a stronger IOP reduction and less need for medication at the cost of a higher rate of complications. If target pressure is attainable by moderate IOP reduction, canaloplasty may be considered for its relative ease of postoperative care and lack of complications.},
