Representative figures of untreated (a) and Ozurdex-treated (b) central retinal vein occlusion eyes at each time point. Retinal hemorrhage was more extensive in (b) compared to (a) at baseline. In untreated eye (a), some dot hemorrhages were still found from 6 months to 12 months. However, no additional hemorrhagic signs were observed after 6 months in Ozurdex -treated eye (b). Vessel tortuosity was dramatically improved after 1 month in treated eye (b), while engorged vessels remained almost unchanged during the 12-month follow-up in untreated eye (a). Edematous change in the disc was more prominent in treated eye (b), and it gradually resolved throughout the follow-up period
