Ophtalmologie. Thérapies anti-vasoprolifératives

The most important recent advance in the treatment of neovascular age-related macular degeneration (AMD) is the development of antivascular endothelial growth factor (anti-VEGF) therapeutic agents that preserve and improve visual acuity by arresting choroidal neovascular growth and reducing vascular permeability. Two anti-VEGF agents, ranibizumab and pegaptanib sodium, are currently approved by Swissmedic for the treatment of neovascular AMD. A third anti-VEGF agent, bevacizumab, is currently used as an off label treatment option for exsudative AMD. Other anti-VEGF agent strategies that have shown efficacy include among others, small interfering RNA agents to silence the VEGF gene and receptor and the fusion protein VEGF trap. Anti-VEGF therapies have been used successfully in the clinic, encouraging their use in the treatment of other neovascular and exudative eye diseases.
