Safety and Effectiveness of Bevacizumab Intravitreal Injections in the Treatment of Macular Edema Secondary to Retinal Vein Occlusion

Lack of an effective treatment for macular edema secondary to central retinal vein occlusion and the bad response to grid laser treatment in patients with macular edema secondary to branch retinal vein occlusion, together with the high incidence of the pathology and the great functional loss in the patients that suffer from it has motivated the search for new therapeutic approaches. In recent times, intravitreal bevacizumab has been tested in clinical practice in small series of patients with this pathology, whether as first treatment or after failure of grid laser treatment with good functional results in short series. However, no retreatment information is available, although preliminary results from published series are good.
