Dendrimer compositions and methods for the treatment of one or more inflammatory and/or angiogenic diseases and/or disorders of the eye include hydroxyl-terminated dendrimers complexed or conjugated with one or more active agents for the treatment or alleviation of one or more symptoms of the diseases of the eye, and/or for diagnosing the diseases and/or disorders of the eye. The dendrimers may include one or more ethylene diamine-core poly(amidoamine) (PAMAM) hydroxyl-terminated generation-4, 5, 6, 7, 8, 9, or 10 dendrimers. The active agents may be VEGFR tyrosine kinase inhibitors including sunitinib or analogues thereof. Preferably, the compositions are suitable for administration via a systemic route to target activated microglia/macrophages in retina/choroid.

The present invention provides compositions comprising PAMAM dendrimers conjugated with one or more biologically active agents, and their use systemically to target activated microglia/macrophages in retina/choroid and generally, inflammatory and/or angiogenic diseases of the eye.
