Patients and methods: We assessed outcomes of surgery, rate of revision surgeries, patients' mood, and influence of postoperative care on QoL, surgery interference with daily activities, and postsurgical complaints. Patients completed the QoL questionnaire 24 months after surgery. Results: Patients who underwent CP (n=175) were compared to TE patients (n=152). In the CP group, 57\% of patients expressed high satisfaction, while 41\% of patients in the TE group said they were highly satisfied. The satisfaction difference was statistically significant (P=0.034). Significantly fewer second surgeries were needed after CP (8\% CP versus 35\% TE, P<0.001). Patients were more positive in the CP group (54\% CP versus 37\% TE, P<0.009). Stress related to postoperative care was lower in the CP group compared to the TE group (14\% versus 46\%). Difficulties with activities of daily living, such as reading, were much lower or even nonexistent after CP, and complaints like eye burning or stinging were significantly lower in the CP group. Conclusions: Compared with TE, CP is associated with less QoL impairment and higher patient satisfaction after surgery. However, long-term data on intraocular pressure reduction after surgery are needed to confirm long-term patient satisfaction with this surgery.}, language = {en} } @article{MatlachDhillonHainetal.2015, author = {Matlach, Juliane and Dhillon, Christine and Hain, Johannes and Schlunck, G{\"u}nther and Grehn, Franz and Klink, Thomas}, title = {Trabeculectomy versus canaloplasty (TVC study) in the treatment of patients with open-angle glaucoma: a prospective randomized clinical trial}, series = {Acta Ophthalmologica}, volume = {93}, journal = {Acta Ophthalmologica}, doi = {10.1111/aos.12722}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-149263}, pages = {753-761}, year = {2015}, 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.}, language = {en} } @article{LangMessmerGeerlingetal.2015, author = {Lang, Stefan J. and Messmer, Elisabeth M. and Geerling, Gerd and Mackert, Marc J. and Brunner, Tobias and Dollak, Sylvia and Kutchoukov, Borislav and B{\"o}hringer, Daniel and Reinhard, Thomas and Maier, Philip}, title = {Prospective, randomized, double-blind trial to investigate the efficacy and safety of corneal cross-linking to halt the progression of keratoconus}, series = {BMC Ophthalmology}, volume = {15}, journal = {BMC Ophthalmology}, number = {78}, doi = {10.1186/s12886-015-0070-7}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-151498}, year = {2015}, abstract = {Background: Corneal cross-linking is widely used to treat keratoconus. However, to date, only limited data from randomized trials support its efficacy. Methods: The efficacy and safety of corneal cross-linking for halting progression of keratoconus were investigated in a prospective, randomized, blinded, placebo controlled, multicentre trial. Twenty-nine keratoconus patients were randomized in three trial centres. The mean age at inclusion was 28 years. Longitudinal changes in corneal refraction were assessed by linear regression. The best corrected visual acuity, surface defects and corneal inflammation were also assessed. These data were analysed with a multifactorial linear regression model. Results: A total of 15 eyes were randomized to the treatment and 14 to the control group. Follow-up averaged 1098 days. Corneal refractive power decreased on average (+/-standard deviation) by 0.35 +/- 0.58 dioptres/year in the treatment group. The controls showed an increase of 0.11 +/- 0.61 dioptres/year. This difference was statistically significant (p = 0.02). Conclusions: Our data suggest that corneal cross-linking is an effective treatment for some patients to halt the progression of keratoconus. However, some of the treated patients still progressed, whereas some untreated controls improved. Therefore, further investigations are necessary to decide which patients require treatment and which do not.}, language = {en} } @phdthesis{Sauer2015, author = {Sauer, Johannes}, title = {Postoperative gesundheitsbezogene Lebensqualit{\"a}t (HRQL) nach Trabekulektomie vs. Kanaloplastik}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-141492}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2015}, abstract = {Postoperative gesundheitsbezogene Lebensqualit{\"a}t (HRQL) nach Trabekulektomie vs. Kanaloplastik.

Ziel dieser Studie war es zu untersuchen, ob die Signalqualit{\"a}t des pattern-onset VEPs erh{\"o}ht und die Reproduzierbarkeit der Signalantworten mit Hilfe des mfVEPs verbessert werden kann, indem man einzelne mfVEPs gleichrichtet. 20 Normalpersonen nahmen an dieser Untersuchung teil. Ein kortikal skaliertes Schachbrettmuster von 30° Gr{\"o}ße wurde in 6 keilf{\"o}rmige Teilfelder unterteilt. Innerhalb jedes Teilfeldes wurden kortikal skalierte Schachbrettmuster mit einer mittleren Leuchtdichte von 50 cd/m2 und einem Kontrast von 99\% im pattern-pulse Verfahren pr{\"a}sentiert. Die durchschnittliche Stimulationsfrequenz betrug 2,0 Hz. MfVEPs des rechten Auges wurden {\"u}ber eine Oz-Fpz und bipolare Ableitung zwischen zwei 4 cm um das Inion angeordnete Elektroden abgeleitet. Durch Summierung der 6 mfVEP Ableitungen mit unterschiedlichen Vorzeichen wurden zwei Ganzfeld-VEPs synthetisiert, von denen eine die fr{\"u}hen C1 und C2 Komponenten, die andere die sp{\"a}te C3-Komponente des pattern onset VEPs erh{\"o}hte. Amplituden und Latenzunterschiede zwischen den synthetisierten Antwortkurven und der Ganzfeldantwort aller 6 Felder wurden auf Signifikanz getestet. Die Daten legen nahe, dass die inter-individuelle Variabilit{\"a}t des Standard Ganzfeld pattern onset VEPs auf die Ausl{\"o}schung von großen und wenig variablen VEP Signalen aus unterschiedlichen Bereichen des Gesichtfsfeldes zur{\"u}ckgef{\"u}hrt werden kann. Die Gleichrichtung dieser VEP-Signale f{\"u}hrte zu einem hochsignifikanten Anstieg der Amplitude und zu einer reduzierten Variabilit{\"a}t der synthetisierten Ganzfeldantworten im Vergleich zur gemessenen Ganzfeldantwort. Neben der objektiven Perimetrie kann die Anwendung multifokaler Techniken zu einer gesteigerten Sensitivit{\"a}t beim Aufsp{\"u}ren visueller Pathologien f{\"u}hren verglichen mit Standard Ganzfeldmessungen.}, subject = {Patterns}, language = {de} }
