Content: The clot obstructs the blood flow to the retina, and the vision blacks-out. When the clot breaks up, the blood flow returns, as does the vision. The source of the clot (or embolus) is usually from the carotid arteries leading up the neck to the brain, or from the heart. The embolus may be a cholesterol crystal, a calcium deposit, or a true blood clot. This problem falls into the same category as "transient ischemic attacks" (or TIA's), which may herald a stroke. Vascular evaluation and possibly anti-coagulation (use of blood thinners) is indicated for this problem. Other problems which cause a temporary loss of vision include: Obstruction of the vertebral arteries, which course up the back of the neck and supply the visual part of the brain. People which this problem may notice temporary dimming of vision affecting both eyes, and possibly imbalance. Increased intracranial pressure (the pressure of the fluid around the brain) can cause momentary lapses of vision especially when moving, such as standing from a sitting position.
