  • Patent number: 6270749
    Abstract: The use of texaphyrins for ocular diagnosis and therapy is provided, especially use of photosensitive texaphyrins for photodynamic therapy of conditions of the eye characterized by abnormal vasculature, such as macular degeneration, or pterygium, for example. The photosensitive texaphyrin may be a free-base texaphyrin or may be metallated with a diamagnetic metal. Preferably, the photosensitive texaphyrin is metallated with lutetium. Due to the dual wavelength absorption of texaphyrins, i.e., at 400-500 nm and at 700-800 nm, especially about 732 nm, as compared to porphyrins, texaphyrins are more effective and versatile for use in humans as compared to porphyrins. Texaphyrins serve as effective contrast agents in ocular angiography.

  • Patent number: 6265435
    Abstract: A loop diuretic is applied topically to the corneal epithelium along with a therapeutic ophthalmic drug in an aqueous solution. The loop diuretic acts to temporarily block the discrete ion channels for outward Na+2Cl−K+ cotransport through the baso-lateral membrane of the corneal epithelium while allowing inward ion movement, to the anterior chamber unaffected and thus serves to enhance the rate of diffusion of the ophthalmic drug through the cornea to the interior of the eye through solvent drag.
