Tonic Pupil

Tonic Pupil
Top:This patient has almost 2 mm of anisocoria in bright light. Bottom:In relative darkness, the anisocoria is markedly diminished. Anisocoria that is more pronounced in bright light than in dim light suggests that the larger pupil is the abnormal one and that the clinical signs reflect parasympathetic dysfunction. Note, however, that there are a number of exceptions to this general rule.
