Background: The KVWL-QS assists ophthalmologists in the transfer for good clinical praxis into real life. In addition the QS-commission initiated a pilotstudy "Qualitäts-Versorgung bei AMD" (Q‑VERA) in order to test new instruments for improvements. It was analized, if Reading Center (RC) based controls in combination with specific case-management modules can improve the results of IVOM treatment.

Patients and methods: In 5 treatment centers 878 consecutive patients with newly diagnosed AMD (Neu-Patienten) were included, who were treated with the IVAN-scheme. Initial FA and OCT images were transferred electronically to the RC. Also 781 retreatment patients (mean 20.7 IVOM before) with retreatment due to lesion activity were observed.

Results: In 5% of the 878 newly treated patients a discrepancy between RC and treatment center was recorded. In this group the 481 patients, who finished up to the analysis date the 12-month follow-up, the visual function (increase in BCVA) and SD-OCT (reduction in central retinal thickness) results were comparable with large prospective cohorts. This was achieved with 6.5 injections and 10.6 visits over 12 months. In the group of 781 patients with repeated injections the number of injections over 12 months was 7.7 and the number of visits 11.6.

Conclusion: Quality assessment can improve the efficacy of IVOM therapy for AMD patients in real life. In addition to existing structures, electronical exchange by a RC assisted evaluation can further improve the quality by reducing the number of unnecessary treatment visits. The case-management with adherence control, re-call-system and specific information for patients and relatives can specifically increase the long-term adherence and thus the success of the therapy.
