Design outcomes

Primary

MeasureTime frame
regression analysis to look for prognostic factors before and after switch of medication: age, injections before switch, medication before switch, visual acuity (5m distant VA) and retinal thickness (central macular thickness measured by OCT (optical coherence tomography)) at the time of switch

Secondary

MeasureTime frame
change of visual acuity (5m distance VA) and retinal thickness (central macular thickness measured by OCT) 4 weeks after 3 intravitreal injections after switching the medication
