<unk>  revealed by laser Doppler imaging through flow alteration in the upper right<unk>  artery. The diagnosis of<unk>  is made clinically by finding retinal hemorrhages in the distribution of an obstructed retinal vein. * Fluorescein angiography is a helpful adjunct. Findings include delayed venous filling, hypofluorescence caused by hemorrhage and capillary nonperfusion, dilation and tortuosity of veins, leakage due to neovascularization and macular edema. * Optical coherence tomography is an adjunctive test in<unk> . Macular edema is commonly seen on optical coherence tomography exams. Serial optical coherence tomograph is used as a rapid and noninvasive way of monitoring the macular edema. * Laser Doppler imaging reveals dynamic hemodynamics discrepancies between<unk>  arteries and veins, from local vascular resistance increase by the venous<unk> .
