Occlusion and stenosis of right posterior cerebral artery

This condition occurs when the right back brain artery becomes blocked or narrowed, reducing blood flow to the back portions of the brain that control vision and visual memory. Because this artery supplies areas processing what you see on your left side, blockage often causes vision loss on the left side of both eyes and problems recognizing faces or objects. Immediate emergency care is essential to prevent permanent vision loss and brain damage.
