Abstract | PURPOSE: DESIGN: Post hoc analysis of prospective randomized 12-month multicenter clinical trial data. METHODS: PATIENT POPULATION: OBSERVATION PROCEDURE: Assessment of the vitreomacular interface on monthly optical coherence tomography with division of patients into the following categories according to continuous 1-year grading: posterior vitreous detachment (n=154), dynamic release of vitreomacular adhesion (n=32), stable vitreomacular adhesion (n=51). MAIN OUTCOME MEASURES: Mean best-corrected visual acuity (BCVA) letter and central retinal thickness changes at month 12 in the vitreomacular interface groups. RESULTS: Mean BCVA changes at month 12 were +3.5 ( posterior vitreous detachment), +4.3 (release of vitreomacular adhesion), and +6.3 (vitreomacular adhesion) in patients receiving monotherapy (P=.767), and +0.1 ( posterior vitreous detachment), +6.6 (release of vitreomacular adhesion), and +9.2 (vitreomacular adhesion) in patients receiving combination therapy (P=.009). Mean central retinal thickness changes were -113 μm ( posterior vitreous detachment), -89 μm (release of vitreomacular adhesion), and -122 μm (vitreomacular adhesion) in monotherapy (P=.725) and -121 μm ( posterior vitreous detachment), -113 μm (release of vitreomacular adhesion), and -113 μm (vitreomacular adhesion) in combination therapy (P=.924). Mean ranibizumab retreatments during 12 months were 4.9 ( posterior vitreous detachment), 6.6 (release of vitreomacular adhesion), and 5.3 (vitreomacular adhesion) in monotherapy (P=.018) and 4.7 ( posterior vitreous detachment), 5.2 (release of vitreomacular adhesion), and 5.8 (vitreomacular adhesion) in combination therapy (P=.942). CONCLUSION: This study adds evidence that the vitreomacular interface status impacts functional outcomes and retreatment requirements. Patients with posterior vitreous detachment achieve acceptable results with fewer injections in PRN monotherapy, but lose potential vision gain with PDT. Patients with other vitreomacular interface configurations may potentially achieve optimized vision outcomes by combination of antiangiogenic treatment and vaso-occlusive PDT.
