Randomised clinical trial of intravitreal Avastin vs photodynamic therapy and intravitreal triamcinolone: long-term results


Sacu, S; Michels, S; Prager, F; Weigert, G; Dunavoelgyi, R; Geitzenauer, W; Pruente, C; Schmidt-Erfurth, U (2009). Randomised clinical trial of intravitreal Avastin vs photodynamic therapy and intravitreal triamcinolone: long-term results. Eye, 23(12):2223-2227.

Abstract

PURPOSE: To compare 1-year functional and anatomic outcomes of intravitreal bevacizumab (IVB) and photodynamic therapy plus intravitreal triamcinolone (PDT+IVTA) combination in patients with neovascular age-related macular degeneration (AMD). METHODS: In this prospective, randomised, controlled clinical trial, 28 patients were included. All patients were randomised 1 : 1 to 0.04 ml/1 mg of IVB or PDT plus same day 0.1 ml/4 mg IVTA (PDT+IVTA). Follow-up examinations were performed in monthly intervals in IVB group and every 3 months in PDT+IVTA group. Main outcomes were change in mean visual acuity (VA), mean central retinal thickness (CRT) and the mean number of treatments. RESULTS: At month 12, mean VA improved to a 1.5-line gain in IVB group, and lost three letters in PDT+IVTA group (P=0.02). Mean CRT was reduced from 357 microm at baseline to 244 microm at month 12 in IVB group and from 326 microm to 254 microm, respectively, in PDT+IVTA group (P=0.8). The mean number of treatments was 6.8 in the IVB group vs 1.9 in the PDT+IVTA group. No significant local or systemic safety concerns were detected during follow-up time. CONCLUSIONS: Patients treated with IVB showed a significant better VA outcome compared with the PDT+IVTA group despite the fact that both modalities showed equal potency in reducing CRT during a 12-month period.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
