Abstract
The present invention relates to a method for administering a corticosteroid to a posterior segment of an eye. In the method, a sustained release device is implanted to deliver the corticosteroid to the eye. The aqueous corticosteroid concentration remains less than vitreous corticosteroid concentration during release of the corticosteroid from the device.

1-16. (canceled)
A sustained release device including fluocinolone acetonide (FA) disposed therein, which device is dimensioned for implantation in the vitreal cavity of a patient's eye and configured to have a release rate over a time course of at least 4 weeks after implantation, which release rate results in an aqueous humor FA concentration less than one tenth the vitreous FA concentration.
A sustained release device including FA disposed therein, which device is dimensioned for implantation in the vitreal cavity of a patient's eye and configured to have a release rate for said FA to produce a sustained and therapeutic concentration of said FA over a time course of at least 4 weeks effective for reducing neovascularization, edema, diabetic retinopathy, retinal detachment, sickle cell retinopathy, senile macular degeneration, retinal neovascularization, subretinal neovascularization, chronic posterior and pan uveitis, neovascularization resulting following a combined vitrectomy and lensectomy, vascular diseases retinal ischemia, choroidal vascular insufficiency, choroidal thrombosis, neovascularization of the optic nerve, diabetic macular edema, cystoid macular edema, macular edema, retinitis pigmentosa, retinal vein occlusion, proliferative vitreoretinopathy, angioid streak, or neovascularization due to penetration of the eye or ocular injury which release rate results in an aqueous humor FA concentration which does not cause an increase in intraocular pressure over said time course that results in damage to a patient's ocular tissue.
A sustained release device including (FA) disposed therein, which device is dimensioned for implantation in the vitreal cavity of a patient's eye and configured to have a release rate for said FA to produce a sustained and therapeutic concentration of said FA over a time course of at least 4 weeks effective for reducing neovascularization, edema, or diabetic retinopathy, retinal detachment, sickle cell retinopathy, senile macular degeneration, retinal neovascularization, subretinal neovascularization, chronic posterior and pan uveitis, neovascularization resulting following a combined vitrectomy and lensectomy, vascular diseases retinal ischemia, choroidal vascular insufficiency, choroidal thrombosis, neovascularization of the optic nerve, diabetic macular edema, cystoid macular edema, macular edema, retinitis pigmentosa, retinal vein occlusion, proliferative vitreoretinopathy, angioid streak, or neovascularization due to penetration of the eye or ocular injury which release rate results in an aqueous humor FA concentration less than one tenth the vitreous FA concentration.
A sustained release device including a steroid disposed therein, which device is dimensioned for implantation in the vitreal cavity of a patient's eye and configured to release a therapeutically effective amount of steroid, which amount does not produce ocular or systemic steroid-induced toxicity.
A sustained release device including a steroid disposed therein, which device is dimensioned for implantation in the posterior segment of a patient's eye and configured to release a therapeutically effective amount of steroid, which amount does not produce ocular or systemic steroid-induced toxicity.
A sustained release device including FA disposed therein, which device is dimensioned for implantation in the posterior segment of a patient's eye and configured to have a release rate over a time course of at least 4 weeks after implantation, which release rate results in an aqueous humor FA concentration less than one tenth the vitreous FA concentration.
A sustained release device including FA disposed therein, which device is dimensioned for implantation in the posterior segment of a patient's eye and configured to have a release rate for said FA to produce a sustained and therapeutic concentration of said FA over a time course of at least 4 weeks effective for reducing neovascularization, edema, diabetic retinopathy, retinal detachment, sickle cell retinopathy, senile macular degeneration, retinal neovascularization, subretinal neovascularization, chronic posterior and pan uveitis, neovascularization resulting following a combined vitrectomy and lensectomy, vascular diseases retinal ischemia, choroidal vascular insufficiency, choroidal thrombosis, neovascularization of the optic nerve, diabetic macular edema, cystoid macular edema, macular edema, retinitis pigmentosa, retinal vein occlusion, proliferative vitreoretinopathy, angioid streak, or neovascularization due to penetration of the eye or ocular injury, which release rate results in an aqueous humor FA concentration which does not cause an increase in intraocular pressure over said time course that results in damage to a patient's ocular tissue.
A sustained release device including FA disposed therein, which device is dimensioned for implantation in the posterior segment of a patient's eye and configured to have a release rate for said FA to produce a sustained and therapeutic concentration of said FA over a time course of at least 4 weeks effective for reducing neovascularization, edema, diabetic retinopathy, retinal detachment, sickle cell retinopathy, senile macular degeneration, retinal neovascularization, subretinal neovascularization, chronic posterior and pan uveitis, neovascularization resulting following a combined vitrectomy and lensectomy, vascular diseases retinal ischemia, choroidal vascular insufficiency, choroidal thrombosis, neovascularization of the optic nerve, diabetic macular edema, cystoid macular edema, macular edema, retinitis pigmentosa, retinal vein occlusion, proliferative vitreoretinopathy, angioid streak, or neovascularization due to penetration of the eye or ocular injury, which release rate results in an aqueous humor FA concentration less than one tenth the vitreous FA concentration.
