- Hole size controlled by 2 muscles
- Sphincter pupillae
- Circular muscle constricts pupil (Miosis)
- Parasympathetic from Edinger-Westphal near CN3
- Dilator pupillae
- Radial muscle dilates pupil (Mydriasis)
- Sympathetic via:
- Hypothalamus
- Ciliospinal center of Budge and Waller
- Pupil size changes
- Pupil constriction (Miosis)
- Pupil Dilation (Mydriasis)
- Pupil distortion
- Posterior synechiae
- Inflammatory adhesion between lens and iris
- Tear drop-shaped pupil
- Suggests Globe Rupture with iris prolapse
- Pupil fixed, mid-dilated, slightly irregular
- Acute Glaucoma
- Pupil Normal in
- Conjunctivitis
- Absent Pupillary Light Reflex
- Structural lesion
- Hypothermia
- Barbiturate or Opiate overdose
