Visudyne was the treatment of choice for wet macular degeneration until about 2005.It is a light-sensitive drug...which was injected into the patient's bloodstream...and then, a few minutes later...when the drug became concentrated in the abnormal vessels of the eye...the eye was exposed to a special laser...which was absorbed by the drug. The idea was to destroy the abnormal blood vessels (which had a high concentration of the drug) but not damage other nearby tissues.
Visudyne...at the time was quite effective at stabilizing vision...but only very rarely caused visual improvement. The results with Lucentis has been found to be so superior to Visudyne...and as a result...Lucentis has become the first choice of treatment with most retinal specialists.
