Dexamethasone-implant for the Treatment of RVO

January 10, 2013 updated by: Wolfgang Mayer, Ludwig-Maximilians - University of Munich

Twelve Months Experience With a Dexamethasone-implant for the Treatment of Macular Edema Associated With Retinal Vein Occlusion

To evaluate the efficacy and safety of a dexamethasone-implant alone or in combination with bevacizumab. 64 eyes are prospectively investigated. Group 1 (22 CRVO and 16 BRVO) is treated with dexamethasone-implant alone, Group 2 (14 CRVO 12 BRVO) with three consecutive bevacizumab injections followed by a dexamethasone-implant. Recurrences are treated with dexamethasone-implant only. Patients are seen preoperatively and thereafter in monthly intervals. The primary endpoint was BCVA at twelve months.
