  • Patent number: 8591885
    Abstract: Biocompatible intraocular drug delivery systems include a carbonic anhydrase inhibitor therapeutic agent and a polymeric component in the form of an implant, a microparticle, a plurality of implants or microparticles, and combinations thereof. The therapeutic agent is released in a biologically active form, for example, the therapeutic agent may retain its three dimensional structure when released into an eye of a patient, or the therapeutic agent may have an altered three. The implants may be placed in an eye to treat or reduce the occurrence of one or more ocular conditions, such as retinal damage, including glaucoma and proliferative vitreoretinopathy among others.

  • Patent number: 8569272
    Abstract: Compositions, and methods of using such compositions, useful for injection into the posterior segments of human or animal eyes are provided. Such compositions include corticosteroid component-containing particles present in a therapeutically effective amount, a viscosity inducing component, and an aqueous carrier component. The compositions have viscosities of at least about 10 cps or about 100 cps at a shear rate of 0.1/second. In a preferred embodiment, the viscosity is in the range of from about 140,000 cps to about 300,000 cps. The compositions advantageously suspend the particles for prolonged periods of time.
