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.

Treatments for retinal disorders

Disclosed are novel methods of treatment for retinal diseases and conditions including age-related macular degeneration, genetic-based retinal degenerations and retinal detachment. A novel glycan binding protein thought to be a cell surface receptor has been discovered in the retina. The retinal glycan binding receptor is shown to play an important role in promoting assembly of outer segment (OS) membranes by the photoreceptor cells of the eye, a process that is essential for vision. Based on the finding that certain sugars can bind with very high affinity to the retinal glycan receptor and stimulate its function, the invention provides novel therapeutic agents for treatment of retinal diseases that are multivalent N-linked glycans. Preferred pharmaceutical compositions in accordance with the present invention comprise active agents having the general formula: (Gal-GlcNAc).sub.n-Man.sub.3-GlcNAc.sub.2, where n is 1-4. Particularly preferred multivalent glycans are galactosylated, biantennary (NA2), and asialo, galactosylated, triantennary (NA3) oligosaccharides.
