The purpose of this trial is to compare the ability of three different doses of pegaptanib sodium to safely and effectively minimize fluid leakage within the eye, thereby stabilizing or improving vision in patients with wet AMD. The study will also examine the effects of pegaptanib sodium on the cornea and sensory retina of patients with wet AMD.

Inclusion Criteria:

• Subjects of either gender, aged 50 years or greater.
• Subfoveal choroidal neovascularization (CNV) due to AMD.
• Best corrected visual acuity in the study eye between 20/40 and 20/320.
• Normal electroretinogram, and corneal endothelial cell density of 1500 cells/mm2 or more.

Exclusion Criteria:

• Any prior photodynamic therapy (PDT) with Visudyne or thermal laser to the study eye.
