Current Treatment of Retinal Vein Occlusion

Abstract

Retinal vein occlusion (RVO) was first described more than 150 years ago. Even though much has been written about this frequent condition, the aetiopathology appears to be multifactorial with many unclear aspects and varied expression, making it difficult to define treatment guidelines. The management of the patient with RVO is complex and a multidisciplinary approach is required in order to identify and correct the associated risk factors. In the past, laser therapy was the gold standard in RVO, but only modest functional improvement has been shown in branch retinal occlusion forms. Current multicentre studies of intravitreal drugs present them as an option to combine with laser. Anti-vascular endothelial growth factor, corticosteroids and sustained-release implants are attractive options to halt disease progression and achieve a better visual outcome. Consequently, it is useful to clarify some aspects of the pathology that allow better patient management.
