Embodiment Construction

[0033] The preferred embodiments of the present invention and their advantages can be better understood by referring to FIGS. 1-15 , like or corresponding parts being designated by like reference numerals in the different views.

[0034] Figures 1-4 illustrate various parts of the human eye, which are important for a complete understanding of the invention. Referring to FIG. 1 , a human eye 90 is schematically shown. Eye 90 has cornea 92 , lens 93 , vitreous body 95 , sclera 100 , choroid 99 , retina 97 , and optic nerve 96 . Eye 90 is generally divided into anterior segment 89 and posterior segment 88 . The anterior segment 89 of the eye 90 generally includes the portion of the eye 90 anterior to the ora serrata 11 . The posterior segment 88 of the eye 90 generally includes the portion of the eye 90 posterior to the ora serrata 11 . Behind the optic disc 19 , the retina 97 is physically connected to the choroid 99 in a circumferential manner proximal to the planar portion ...

Abstract

Ophthalmic drug delivery devices useful for delivery of pharmaceutically active agents to the posterior segment of the eye are disclosed. The devices may include extensions and / or immobilizing structures and / or geometries to help properly locate, and prevent migration of, the devices.

Description

technical field [0001] The present invention generally relates to biocompatible implants for the local delivery of pharmaceutically active agents into human tissue. In particular, but not by way of limitation, the present invention relates to biocompatible implants for the local delivery of pharmaceutically active agents to the posterior segment of the eye. Background technique [0002] Several diseases and conditions of the back of the eye threaten vision. A few examples are: age-related macular degeneration (ARMD), choroidal neovascularization (CNV), retinopathy (eg, diabetic retinopathy, vitreoretinal disease), retinitis (eg, cytomegalovirus (CMV) retinitis), Uveitis, mid-retinal edema, glaucoma, and neurological disorders. [0003] ARMD is the leading cause of blindness in the elderly. ARMD attacks and blurs the center of vision, making reading, driving, and other specific tasks difficult or impossible. Approximately 200,000 new ARMD patients are diagnosed each year ...
