Comparison of Ranibizumab Monotherapy and Ranibizumab Combination Therapies in Recurrent or Persistent Choroidal Neovascularization Secondary to Age-related Macular Degeneration

"Patients will receive intravitreal dexamethasone using a special drug delivery system and same day intravitreal ranibizumab.~Study medications are initially given at the baseline visit. At each subsequent monthly follow-up visit, ranibizumab is administered if further visual decrease or persistence of sub-/intraretinal fluid is detected in the examination. At month 3, 6, 9 and 12 further treatments with intravitreal dexamethasone in combination with intravitreal ranibizumab are given if leakage is detected in fluorescein or indocyanine green (FLA or ICG) angiography, in case of further vision decrease or persistence of sub-/intraretinal fluid in OCT."

Patients will receive intravitreal ranibizumab monotherapy (cohort 3). Study medications are initially given at the baseline visit. At each subsequent monthly follow-up visit, ranibizumab is administered if further visual deterioration or persistence of sub-/intraretinal fluid is detected in the examination
