  The procedure was complicated by chest pain and the acute onset of blurred vision. Funduscopic examination revealed a white plaque in the left eye, occluding the inferior hemiretinal artery. This was interpreted as a fibrin embolus. [nejm.org]

  BRVO causes a painless decrease in vision, resulting in misty or distorted vision. If the veins cover a large area, new abnormal vessels may grow on the retinal surface, which can bleed into the eye and cause blurred vision. [sneretina.com]
