verteporfin(redirected from Benzoporphyrin derivative)
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 prior to irradiation of the lesion with light from a compatible laser.
