Abstract BACKGROUND AND RESEARCH QUESTION: The authors address the question of whether vascular endothelial growth factor inhibitors (anti-VEGF) lead to better clinical outcomes than current treatments in patients with clinically manifest diabetic macular oedema (DMO), which is the leading cause of vision loss in the working age population in developed countries. METHODS: The authors performed a systematic literature search in common databases and compiled the evidence according to the GRADE methodology. The authors analysed clinically relevant improvement of visual acuity, vision-related quality of life and local or systemic adverse events. RESULTS: In a proportion of patients (on average 25\%), VEGF inhibitors result in better visual acuity (≥15 ETDRS letters or equivalent) than in patients treated with laser photocoagulation or sham injection. The number of injections required for long-term improvement as well as the general long-term efficacy is unknown. The evidence is not sufficient to confirm safety of the products in patients with DMO and does not suggest superiority of a single product. CONCLUSION: For some patients with DMO, VEGF inhibitors seem to be more effective as a short-term treatment option than alternative therapies. The evidence is not of sufficient quality to confirm safety. Decisions on financing should take into account the high price difference between the products and ongoing research.
