Default Trochlear damage

According to wikipedia, damage to trochlear nerve causes weakness of the downward eye movement and subsequent double vision. the affected eye drifts upward relative to the normal eye. According to uworld it says the affected eye is looking towards the nose. which causes double vision. In reality damage to the trochlear nerve causes down and out movement of eye.

Question was a patient is suffering double vision while walking down the stairs. which nerve is damaged.

Can anybody explain what is this.
