English: f2-oed-4-2012-015: Central retinal vein occlusion. (A1) Retinography showing central retinal vein occlusion in a 42-year-old male complaining for blurred vision for the last five days. Retinal hemorrhages can be appreciated in all the four retinal quadrants; (A2) Horizontal foveal-centerred optical coherence tomography scan showing the presence of diffuse retinal cystoid macular edema, and neurosensory foveal detachment. (B1) Retinography after twelve-month follow-up and four intravitreal injections of ranibizumab combined with panretinal photocoagulation. The visual acuity improved from 20/200 at baseline to 20/25; (B2) Complete resolution of the macular edema as evidenced in the optical coherence tomography. A secondary epimacular membrane can be seen as an hyperreflective lineal structure overlying the internal limiting membrane in the nasal side.
