bagel vision

bagel vision
   Also known as doughnut vision and donut vision. The term bagel vision is indebted to the Yiddish verb beigen (to bend, to twist). It is used to denote the visual perception of a punched-out or doughnut-shaped image, caused by a central, *bilateral scotoma. Due to a loss of central vision, and a retention of peripheral vision, faces, for instance, may be perceived in instances of bagel vision as a ring of flesh surrounding a black hole or a void. Bagel vision has been described in relatively rare cases of *visual aura occurring in the context of migraine. In the literature the terms bagel vision, doughnut vision, and donut vision are also used to denote a ring-shaped * scotoma with intact areas of central and peripheral vision.
