Ranibizumab belongs to the class of medications called antivascular endothelial growth factors. It is used to treat “wet,” age-related macular degeneration, a condition where blood vessels behind the retina start to grow and leak blood and fluid. This causes damage to the macula (the centre of the retina) and results in central vision loss that can occur quickly.
Ranibizumab helps to slow down vision loss and may improve vision by stopping the growth and leakage of new blood vessels in the eye.
Ranibizumab is also used to treat decreased vision caused by fluid build-up in the eye as a result of complications of diabetes, blockage of the blood vessel leading away from the macula (retinal vein occlusion) and a condition called pathological myopia.
