  1. 1. + Pupillary Disorder Amaurotic Pupil
  2. 2. + Pupil  The pupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
  3. 3. + Pupillary light reflex is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retina of the eye, thereby assisting in adaptation to various levels of darkness and light, in addition to retinal sensitivity.
  4. 4. +
  5. 5. + Amaurotic pupillary defect is the term applied to an eye that does not even see light owing to severe unilateral retinal or optic nerve disease.
  6. 6. + Amaurotic pupillary defect Amaurotic pupillary response.
  7. 7. + Abnormal Pupils:  Amaurotic, "blind eye," with no light perception as a result of an optic nerve lesion.  A.) Pupils are of equal size.  B.) Neither pupil reacts when the defective eye is stimulated.  1.) There is no direct light response.  2.) There is no consensual light response to the contralateral eye.  C.) Both pupils react when the contralateral eye is stimulated.  1.) Direct light response is present.  2.) Consensual light response is present.  D.) Near reflex is normal.
