METHODS AND COMPOSITIONS FOR PRESERVING PHOTORECEPTOR AND RETINAL PIGMENT EPITHELIAL CELLS
First Claim
1. A method of preserving visual function of an eye of a subject with an ocular condition, wherein a symptom of the ocular condition is the loss of photoreceptor cell viability in the retina of the eye with the condition, the method comprising:
- (a) administering to the eye of the subject an effective amount of a necrostatin and an effective amount of an apoptosis inhibitor thereby to preserve the viability of photoreceptor cells disposed within the retina of the eye; and
(b) after step (a), measuring visual function of the eye.

Abstract
Provided are methods and compositions for maintaining the viability of photoreceptor cells and/or retinal pigment epithelial cells in a subject with an ocular disorder including, for example, age-related macular degeneration (AMD) (e.g., dry or neovascular AMD), retinitis pigmentosa (RP), or a retinal detachment. The viability of the photoreceptor cells and/or the retinal pigment epithelial cells can be preserved by administering a necrosis inhibitor either alone or in combination with an apoptosis inhibitor to a subject having an eye with the ocular condition. The compositions, when administered, maintain the viability of the cells, thereby minimizing the loss of vision or visual function associated with the ocular disorder.

9. A method of preserving the viability of photoreceptor cells disposed within a retina of a mammalian eye following retinal detachment, the method comprising:
administering a necrostatin and an apoptosis inhibitor to the eye in which a region of the retina has been detached in amounts sufficient to preserve the viability of photoreceptor cells disposed within the region of the detached retina, provided that, when necrostatin-1 is the only necrostatin administered, the region is exposed to a final concentration of necrostatin-1 in the eye greater than about 100 μ

11. A method of preserving visual function of an eye of a subject with an ocular condition selected from the group consisting of age-related macular degeneration (AMD), retinitis pigmentosa, macular edema, central areolar choroidal dystrophy, retinal detachment, diabetic retinopathy, BEST disease, adult vitelliform disease, pattern dystrophy, myopic degeneration, central serous retinopathy, Stargardt'"'"'s disease, Cone-Rod dystrophy, North Carolina dystrophy, infectious retinitis, inflammatory retinitis, uveitis, toxic retinitis and light-induced toxicity, wherein a symptom of the ocular condition is the loss of photoreceptor cell viability in the retina of the eye, the method comprising:
reducing the production and/or activity of a RIP-1 kinase and/or a RIP-3 kinase in the eye thereby preserving the viability of the photoreceptor cells disposed with the retina of the eye. - View Dependent Claims (13, 14)
