verteporfin

   Also found in: Wikipedia 0.01 sec.
verteporfin /ver·te·por·fin/ (ver″tĕ-por´fin) a photosensitizing agent that accumulates preferentially in neovasculature, including that in the choroid; used, together with appropriate laser irradiation of the lesion, in the treatment of neovascularization due to disciform macular degeneration, to presumed ocular histoplasmosis, or to pathologic myopia.
verteporfin
[ver′tĕ-por′fin]
a photosensitizing agent that accumulates preferentially in neovasculature, including that in the choroid, such as occurs in age-related macular degeneration, ocular histoplasmosis, or pathologic myopia. The agent is then activated by light of a specific wavelength in the presence of oxygen and causes local damage to the neovascular endothelium followed by vessel occlusion. It is administered intravenously before irradiation of the lesion with light from a compatible laser.

In the smaller study, the control group also received a standard treatment--the drug verteporfin followed by laser light, which activates verteporfin.
A dye called Verteporfin is injected into the patient's bloodstream and then a light in shone into the eye which treats the abnormal blood cells.
Recently, the FDA has approved a new treatment for this distressing condition--the injection of verteporfin into the plasma of the eyeball, followed by shining light of a specific wavelength into the plasma to activate the verteporfin.
