Week 16 (Visit 6): This study visit will allow collection of eye exam data, vision, eye pressure, and OCT. This visit will last approximately 1-2 hours. At this visit, the study doctor will determine the need for retreatment with the patient's assigned study treatment regimen. If they do not receive treatment, it is because the initial treatments administered at the baseline (visit 2) are still working and patients will be re-assessed for retreatment at study visit 7. The next study visit (Visit 7) will be scheduled in 4-5 weeks. Someone from the study doctor's office will contact the patient prior to their visit to remind them of this next visit.
