scotoma (skoh-TOH-muh) - n., an area of diminished vision within the visual field, esp. the blind spot.
Especially the place where the optic nerve enters the eye, preventing any photoreceptors from covering that location, but as a medical term any area of impaired or lost vision within an otherwise good field of vision. FWIW, the blind spot was first documented by Edme Mariotte, a French physicist and priest, in 1660. From New Latin scotōma, from Late Latin, where it had the meaning dim sight, from Greek skotōma, dizziness, from skotoun, to darken, from skotos, darkness.
