PURPOSE: To report successful treatment of persistent retinal edema associated with retinal vascular occlusion with ranibizumab after initial failure with bevacizumab intravitreal injections.
METHODS: A retrospective chart review of all patients undergoing treatment with intravitreal bevacizumab for retinal vascular occlusion was undertaken. Clinical features of patients who were switched to monthly ranibizumab because of persistent and/or worsening retinal edema despite multiple (six or more) monthly intravitreal bevacizumab injections were selected for review. The type of retinal vascular occlusion, age of the patient, visual acuity at each visit, number of intravitreal bevacizumab injections, optical coherence tomography findings at each visit, fluorescein angiography, and number of intravitreal ranibizumab injections with optical coherence tomography findings at each subsequent visit were recorded.
RESULTS: Six patients (five women and one man) were identified. Age ranged from 56 years to 74 years. Five had central retinal vein occlusion and one a branch retinal vein occlusion. All were treated with at least 6 sequential intravitreal bevacizumab injections (range, 6-13) before treatment with ranibizumab. All demonstrated an immediate and marked reduction in retinal edema that had not occurred with any of the previous treatments. The average central foveal thickness on optical coherence tomography was 592 µm before ranibizumab injection and 346 µm after the injection. Visual acuity improved in four of the six patients and was stable in the remaining two patients.
CONCLUSION: Eyes of patients with persistent macular edema secondary to retinal vein occlusion despite bevacizumab may experience prompt improvement after initiation of intravitreal ranibizumab injections.
