  • Publication number: 20080112922
    Abstract: Ophthalmically therapeutic materials, such as liquid-containing compositions and polymeric drug delivery systems, include a therapeutic component which includes an alpha 2 adrenergic receptor agonist that is cleared from the anterior segment of an individual's eye to which the material is administered. The alpha 2 adrenergic receptor agonist may have a vitreal half-life greater than about three hours. The present materials are effective in treating an ocular condition(s) that affect the anterior segment of an eye, or the anterior and posterior segment of the eye. The materials are suitable for intravitreal or periocular administration and can provide prolonged drug delivery and therapeutic benefits to patients to which the materials have been administered. The alpha 2 adrenergic receptor agonists can be provided in liquid-containing formulations and/or bioerodible and/or non-bioerodible polymeric implants and microparticles. Methods of making and using the present materials are also described.

  • Publication number: 20060182781
    Abstract: Biocompatible microparticles include a ophthalmically active cyclic lipid component and a biodegradable polymer that is effective, when placed into the subconjunctival space, in facilitating release of the cyclic lipid component into the anterior and posterior segments of an eye for an extended period of time. The cyclic lipid component can be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the cyclic lipid component can be encapsulated by the polymeric component. The present microparticles include oil-in-oil emulsified microparticles. The subconjunctivally administered microparticles can be used to treat or to reduce at least one symptom of an ocular condition, such as glaucoma or age related macular degeneration.

  • Publication number: 20060106104
    Abstract: Ophthalmic compositions including compatible solute components and/or polyanionic components are useful in treating eyes, for example, to relieve dry eye syndrome, to protect the eyes against hypertonic insult and/or the adverse effects of cationic species on the ocular surfaces of eyes and/or to facilitate recovery from eye surgery.

  • Publication number: 20050271705
    Abstract: Biocompatible intraocular implants include a retinoid component and a biodegradable polymer that is effective to facilitate release of the retinoid component into an eye for an extended period of time. The therapeutic agents of the implants may be associated with a biodegradable polymer matrix, such as a matrix that is substantially free of a polyvinyl alcohol. 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.

  • Publication number: 20050244475
    Abstract: Biocompatible intraocular implants include a tyrosine kinase inhibitor and a biodegradable polymer that is effective to facilitate release of the tyrosine kinase inhibitor into the vitreous of an eye for an extended period of time. The therapeutic agents of the implants may be associated with a biodegradable polymer matrix, such as a matrix that is substantially free of a polyvinyl alcohol. The implants can be placed in an eye to treat or reduce the occurrence of one or more ocular conditions, such as posterior ocular conditions.
