Patent Claims: 1. A method of treating geographic atrophy in a human subject, the method comprising administering by intravitreal injection, to said subject, 2 mg/eye of a pegylated aptamer; wherein the aptamer comprises the sequence fCmGfCfCGfCmGmGfUfCfUfCmAmGmGfCGfCfUmGmAmGfUfCfU mGmAmGfUfUfUAfCfCfUmGfCmG-3T (SEQ ID NO: 26), wherein fC and fU=2′-fluoro nucleotides, mG and mA=2′-OMe nucleotides, all other nucleotides are 2′-OH, and 3T indicates an inverted deoxythymidine, or a salt thereof; wherein the pegylated moiety has the following structure: wherein the pegylated aptamer is administered to the subject monthly; and wherein the method slows or inhibits loss of visual acuity in the human subject.
