The question of safety using off-label intravitreal bevacizumab (Avastin Genentech, South San Francisco, California, USA; Roche AG, Basle, Switzerland) is a concern among ophthalmologists around the globe. This is one of the key aspects of The international intravitreal bevacizumab safety survey: using the internet to assess drug safety worldwide published by A Fung et al 1 ( see page xxx ). Why else would 70 centres from 12 countries voluntarily report on >7000 injections in >5000 patients using an internet-based questionnaire within just 6 months? The safety survey reported no drug-related adverse events for intravitreal bevacizumab injections beyond the level of incidence rates seen in control groups of current anti-vascular endothelial growth factor (VEGF) trials in ophthalmology. No single adverse event reported was above 0.21% over a mean follow-up of 3.5 months. On the one hand, a self-reported safety survey may have the risk of underestimating adverse events, which was discussed by the authors; on the other hand, hardly any prospective clinical trial would be able to obtain safety data from such a diversity of centres, using different techniques for preparing and injecting bevacizumab and for …
