The present invention relates to the use of cyclic oligosaccharides as chemical complexants of lipofuscin bisretinoids (A2E) to prevent and treat eye (i.e., retinal or macular) disease. Monomeric, dimeric, multimeric, or polymeric oligosaccharide rings act as pharmacologic agents to prevent and treat ophthalmologic disorders triggered by the accumulation of lipofuscin in the retinal pigment epithelium (RPE), which occurs as a consequence of either genetic disorders, such as Stargardt Disease (SD) and Best Disease (BD), or aging, such as Age-Related Macular Degeneration (AMD), or other diseases, such as retinitis pigmentosa, and cone-rod dystrophy.

The present invention relates to processes for production of Very Long Chain Polyunsaturated Fatty Acids (VLC-PUFAs). The present invention also relates to compositions (e.g., nutritional supplements and food products) containing such VLC-PUFAs. In one embodiment, the present invention is directed to methods for biosynthesis and production of the VLC-PUFAs described herein (particularly C28-C38 PUFAs, also referred to herein as supraenes or supraenoics) by the expression, in a production host cell, of the full or partial sequence(s) of Elovl4 DNA/mRNA nucleic acids or ELOVL4 protein sequences encoded thereby, from any species (prokaryotic or eukaryotic) for use in the biosynthesis, production, purification and utilization of VLC-PUFAs in particular by the elongation of C18-C26 saturated fatty acids and PUFAs. The composition of the invention comprises, in various embodiments, a dietary supplement, a food product, a pharmaceutical formulation, a humanized animal milk, an infant formula, a cosmetic item and a biodiesel fuel for example. A pharmaceutical formulation can include, but is not limited to: a drug for treatment of neurodegenerative disease, a retinal disorder, age related maculopathy, a fertility disorder, particularly regarding sperm or testes, or a skin disorder.

Intravitreal administration of a JNK-inhibitory peptide less than 150 amino acids in length, containing at least one D-amino acid, and having (a) a JNK-inhibitory sequence of at least any of SEQ ID NO: 1 and SEQ ID NO: 2, and (b) a transport sequence of at least any of SEQ ID NO: 3 and SEQ ID NO: 4 suppressed spermidine-induced retinal pigment epithelial damage, tunicamycin-induced photoreceptor cell damage, and laser-induced choroidal neovascularization. Thus, the JNK-inhibitory peptide of the present invention is useful for prophylaxis or therapy of a retinal disease. By the use of this JNK-inhibitory peptide, a drug and a method are provided which are capable of preventing or treating a retinal disease even by topical administration to the eye, and use of the JKN-inhibitory peptide for manufacturing the drug is also provided.

The present invention is directed to VEGF-2 polynucleotides and polypeptides and methods of using such polynucleotides and polypeptides. In particular, provided are methods of treating retinal disorders with VEGF-2 polynucleotides and polypeptides.

An intra ocular implant consisting of optical elements, adapted to forming images on the retina, especially useful in treating presbyopic patients, patients with AMD, patients with other diseases of the retina, and patients in which future development of retinal disorders may occur. An intra ocular implant wherein at least one mirror is operationally connected to the action of the ciliary muscle or its effect on the zonules and capsule of the natural lens; and wherein the mirror is adapted to change curvature, position or optical properties, such that bringing a plurality of objects at different distances into focus is facilitated in presbyopic patients. A lens assembly comprising an intra ocular lens and, an adjustable external or contact lens comprising at least in part of light polarizing material; the assembly at least partially polarizes at least part of the central visual field, at least part of the peripheral visual field or both in any angle.

The invention relates to stem cells isolated from the retina of mammals and retinal cells differentiated from these stem cells. The invention also relates to a method of isolating retinal stem cells and inducing retinal stem cells to produce retinal cells. Retinal stem cells may also be induced in vivo to produce retinal cells. The invention also includes pharmaceuticals made with retinal stem cells or retinal cells which may be used to restore vision lost due to diseases, disorders or abnormal physical states of the retina. The invention includes retinal stem cell and retinal cell culture systems for toxicological assays, for isolating genes involved in retinal differentiation or for developing tumour cell lines.

The present invention provides a method of treating edematous retinal disorders. The method comprises administration of a pharmaceutical formulation comprising a hydrolysis-resistant P2Y receptor agonist to stimulate the removal of pathological extraneous fluid from the subretinal and retinal spaces and thereby reduce the accumulation of said fluid associated with retinal detachment and retinal edema. The P2Y receptor agonist can be administered with therapeutic and adjuvant agents commonly used to treat edematous retinal disorders. The pharmaceutical formulation useful in this invention comprises a P2Y receptor agonist with enhanced resistance to extracellular hydrolysis, such as dinucleoside polyphosphate compounds, or hydrolysis-resistant mononucleoside triphosphates.
