Disclosed are methods and materials for visualizing or treating vasculature. The methods and materials in this invention relate to selective and non- invasive visualization, or treatment such as chemical occlusion, of vasculature in the mammalian eye. The methods utilize fluorescent dyes and tissue-reactive substances encapsulated within heat-sensitive liposomes whic h are subsequently heated to release the contents thereof at a predetermined anatomical locus. The methods of this invention further utilize tissue- reactive agents which, when activated, are effective to cause localized tiss ue damage and occlusion of blood vessels and/or blood sinuses. The materials of this invention relate to diagnostic reagents and kits for visualizing or treating a mammalian blood vessel or sinus.
