Macular edema due to retinal vein occlusion is the second most common cause of vascular vision impairment. The authors refer two case reports that describe different response to treatment with OZURDEX, biodegradable injectable implant slowly releasing 700 µg dexamethasone.
Treatment with corticosteroids is effective also in the case of cystic retinal edema, but its effect can be temporary. The most common adverse events are elevation of intraocular pressure and cataract development.
