A syndrome that you might see in the clinical literature involving the superior colliculus is called the dorsal midbrain or PARINAUD syndrome. This is usually caused by a tumor of the pineal gland that compresses the superior colliculi and results in a paralysis of UPWARD gaze. It is not clear if this deficit is due to involvement of ONLY the superior colliculi. A center for vertical eye movements lies just rostral to the superior colliculi and could be involved. For now, REMEMBER-PARINAUD SYNDROME===PARALYSIS OF UPWARD GAZE.
