Results
The usefulness of photodynamic therapy was evaluated and published, and a related manuscript is under preparation. The feasibility of suspending anti-VEGF therapy was assessed; suspension was possible with subretinal fluid and retinal pigment epithelial detachment but difficult with intraretinal fluid and subretinal hyperreflective material. We also examined binocular-onset AMD and evaluated the impact of cataract surgery, with part of the data presented.
