Background: To study the efficacy and safety of a new intravitreal implant (sustained release of dexamethasone, Ozurdex®) recently approved in Switzerland for the treatment of macular edema secondary to retinal vein occlusion in a clinical setting.Patients and Methods: Prospective non-consecutive study of patients with macular edema secondary to central retinal vein occlusion or branch retinal vein occlusion treated with implant of dexamethasone 0.7 mg. Follow-up visits were performed at day 1, week 1 and monthly thereafter. ETDRS best corrected visual acuity, Goldmann tonometry and macular thickness on SD-OCT were registered. Retreatment was carried out on a pro re nata basis starting from month 3.Results: Fifteen eyes of 15 patients were included (8 branch retinal vein occlusions, 7 central retinal vein occlusions). 33 % of the patients achieved 3 lines or more of vision gain. The central retinal vein occlusion subgroup showed a mean decline in visual acuity at month 3. A reduction of 36 % of macular edema was already observed at day 1. All maculae were dry at month 1. The mean time of recurrence of macular edema for both groups was 4.6 months. A similar reduction of macular edema was obtained after a second implantation. An intraocular pressure increase of ≥ 20 % was observed after the first implantation in 53 % of patients.Conclusion: Our study showed efficacy and safety of intravitreal dexamethasone implant in the treatment of macular edema due to retinal vein occlusion. Anatomical efficacy was observed at day 1 but seems to have shorter effect than previously published data. No serious side effects were observed.
