Long-Term Efficacy and Safety of Modified Canaloplasty Versus Trabeculectomy in Open-Angle Glaucoma.

BACKGROUND: To evaluate the long-term efficacy and safety of modified canaloplasty versus trabeculectomy in open-angle glaucoma. METHODS: In total, 210 subjects with open-angle glaucoma were included. 70 were treated with Mitomycin C-augmented modified canaloplasty with enhanced subconjunctival filtration and 140 with Mitomycin C-augmented trabeculectomy. Cases were matched 1:2 by sex and age. RESULTS: In canaloplasty and trabeculectomy groups, 61.4% and 57.9% of participants were female. Mean age was 60.0 ± 13.9 and 63.0 ± 12.2 years, median follow-up time was 4.6 [IQR 4.3, 5.05] years and 5.8 [IQR 5.4, 6.3]. Strict success was achieved in 20.0% and 56.4%, complete success in 24.3% and 66.4%, and qualified success in 34.3% and 73.6% (each p < 0.001). Kaplan-Meier survival analysis showed a better survival probability for trabeculectomy than for canaloplasty (p < 0.001) and Cox regression analysis revealed an HR of 6.03 (95%-CI 3.66, 9.93, p < 0.001) after canaloplasty. Trabeculectomy showed superiority in terms of IOP decrease (9.2 ± 7.9 mmHg vs. 13.7 ± 10.4 mmHg, p = 0.002), use of AGM (50.0% vs. 10.7%, p < 0.001), and the number of revision surgeries (41.4% vs. 21.4%, p = 0.004). Occurrence of complications was similar in both groups (14.5% vs. 7.5%, p = 0.19). CONCLUSIONS: Trabeculectomy showed superiority in efficacy and equality in safety compared to modified canaloplasty.

[German national survey of lecturers in ophthalmology on student teaching in the 2020/21 corona pandemic]. / Deutschlandweite Befragung der Lehrbeauftragten in der Augenheilkunde zur studentischen Lehre in der Corona-Pandemie 2020/21.

BACKGROUND: The corona pandemic has had a significant impact on the conditions of university student teaching. Due to the pandemic-related contact restrictions, digital teaching formats were widely used instead of the previous face-to-face teaching. In the summer semester of 2020 students received this well and evaluated it positively in recent publications. In this work, the main focus was on the experiences and assessments of teachers in ophthalmology during the winter semester 2020/2021. METHODS: By means of two anonymous surveys via online questionnaires, the lecturers in ophthalmology of German university hospitals as well as internal and external lecturers and staff members of the student teaching of the Department of Ophthalmology of the University Medical Center Mainz were asked about their experiences with the implementation of digital teaching. RESULTS: In this context 95% of the teaching staff of ophthalmology departments of university hospitals in Germany stated that they had established digital teaching concepts at the latest since the corona pandemic. Hybrid formats with a proportion of face-to-face teaching were used by 68%. A wide variety of teaching formats were used. Difficulties were also encountered, particularly in interaction with students. Despite predominantly digital teaching, examinations continued to be held in face-to-face settings; only 18% of respondents stated that they had conducted online examinations. In the future, 86% of respondents want to integrate digital formats into their teaching concepts and establish them as a supplement to existing face-to-face teaching. CONCLUSION: The development of student teaching during the corona pandemic can serve as an opportunity for shaping the future education of medical students in ophthalmology.
