Abstract: A method of treating diabetic retinopathy in a subject in need thereof includes administering to the subject a therapeutically effective amount of one or more agents that act as a trap of reactive aldehydes and/or inhibit diabetes-induced superoxide generation and capillary degeneration regulated by GPCR signaling pathways.

Abstract: A pharmaceutical composition includes a retinylamine derivative having the following formula (I): where R1 is an amino acid residue, a dipeptide or a tripeptide that is linked to the retinylamine by an amide bond.

Abstract: Compositions of and methods for using synthetic retinal derivatives as retinoid replacements and opsin agonists are provided.

Abstract: A method of determining retinal degeneration of photoreceptors and/or the retinal pigment epithelium (RPE) of a subject includes measuring two-photon induced fluorescence inner and/or outer segments of the photoreceptor cells and/or retinal pigment epithelium to assess photoreceptor cell death and retinal pigment epithelium cell death or degeneration.

Abstract: A method of treating or preventing age-related retinal dysfunction involves administering to a patient a pharmaceutically effective amount of a synthetic retinal derivative repeatedly over a duration of at least about 3 months. Effective synthetic retinal derivatives include 9-cis-retinyl esters, 11-cis-retinyl esters, derivatives and congeners thereof, and combinations thereof. Suitable ester substituents include carboxylates of C1-monocarboxylic acids and C2-C22 polycarboxylic acids.

Abstract: Compositions of and methods for using synthetic retinal derivatives as retinoid replacements and opsin agonists are provided.

Abstract: Methods and compositions for stabilizing opsin protein, such as a Pro23His mutant opsin protein, in a vertebrate visual system, by administration of opsin-binding synthetic retinoids, are provided. The mutant opsin protein binds to the synthetic retinoid, which stabilizes the mutant opsin protein and/or ameliorates the effects of the mutant opsin protein on the vertebrate visual system.

Abstract: A composition includes a polysaccharide at least one retinoid linked to at least one monosaccharide subunit of the polysaccharide with a covalent linkage. The linkage being degradable by hydrolysis during digestion of the composition to provide controlled, delayed, and/or sustained delivery of the at least one retinoid upon enteral administration of the composition to a subject.

Abstract: A method of treating an ocular disorder in a subject associated with aberrant all-trans-retinal clearance in the retina, the method comprising administering to the subject a therapeutically effective amount of a primary amine compound of formula: wherein R1 is an aliphatic and/or aromatic compound.

Abstract: A method of treating an ocular disorder in a subject includes administering to the subject a therapeutically effective amount of an agent that modulates at least one target in a signaling cascade associated with light induced retinal degeneration, aberrant all-trans-retinal accumulation, and/or generation of reactive oxygen species (ROS).
