Baseline/Randomization (Visit 2): If patients are eligible to receive study treatment(s) they will be scheduled for a baseline randomization study visit to allow collection of eye exam data (intraocular pressure, inflammatory cells, abnormal blood vessels) and ocular coherence tomography OCT. This is the same type of eye exam and OCT patients typically undergo at a retina specialist's office. Additionally, patients will undergo a special vision test and an intravenous fluorescein angiogram to assess retinal circulation. This visit will last approximately 2 hours. The next study visit (Visit 3) will be scheduled in 4-5 weeks. Someone from your study doctor's office will contact the patient prior to the baseline visit to remind you of this next visit
