A conjugate gaze palsy is inability to move both eyes together in a single horizontal (most commonly) or vertical direction. Parinaud syndrome, also called the dorsal mid brain syndrome, sylvian aqueduct syndrome, and pretectal syndrome, includes multiple clinical signs, the most prominent of which is paralysis of upward gaze ( 1, 2). Compression of the superior colliculus may result in upward gaze palsy (Parinaud syndrome), and effacement of the cerebral aqueduct may lead to obstructive hydrocephalus (Figure 10.
