Supranuclear vertical gaze palsy and eyelid retraction due to dorsal midbrain ischemia

Introduction: Paralysis of gaze, Pseudo-Argyll Robertson pupils, convergence-retraction nystagmus and eyelid retraction (Collier's sign) are typical signs of a dorsal midbrain syndrome (also known as Parinaud syndrome). The dorsal midbrain syndrome is caused by a damage to certain mesencephalic nuclei. Case Description: We present a case of dorsal midbrain syndrome with typical clinic and radiological findings. Discussion: This case shows that careful examination of eyes and good neuroanatomical knowledge are sufficient for localization of damage.
