This invention provides a polymeric drug delivery system including a hydrogel containing one or more drugs for the treatment of a posterior segment disease. Exemplary drugs are anti-angiogenesis compounds for the treatment of macular degeneration. Allowing passive transference of this drug from a dilute solution into the hydrogel produces the delivery system. The hydrogel, when placed in contact with the eye, delivers the drug. The delivery of the drug is sustained over an extended period of time, which is of particular utility in the eye, which is periodically flushed with tears. This sustained delivery accelerates the treatment process while avoiding potential damaging effects of localized delivery of high concentrations of compounds, e.g., from eye drops.

Ocular solutions containing an antioxidant provide beneficial properties, for example, the antioxidant scavenges free radicals in the solution which may cause the solution to deteriorate. However, antioxidants are themselves extremely susceptible to oxidation. A stabilizing agent for the antioxidant retards or prevents the antioxidant from undesirable reactions and thus enhances its ability to stabilize the ocular solution. This in turn enhances the physiological properties of the ocular solution, which may be a topical solution such as eye drops, or a surgical ocular irrigation or volume replacement solution.
