| Popis: | Please view Fig 1 and watch the accompanying video clip (Video 1). Video 1. Click here to view the video. Reproduced with permission of Akshaya Vachharajani, MD, copyright 2018. The most likely cause of this infant’s examination findings is: (Note: More than 1 option is possible.) The video clip depicts an intubated term female infant with abnormal right eye findings. The infant’s left eye is normal: the eye opens completely and the left pupil reacts normally to light (video time 0:06 seconds). Her left eyeball is moving downward in the midline (video time 0:21 seconds), medial, and lateral (video times 0:23 and 0:25 seconds, respectively) positions. In contrast, her right eye does not open (video time 0:02 seconds), is immobile, and she has a right gaze preference with the right eyeball fixed downward and outward. This gaze preference persists even when the left eye is moving laterally (video time 0:23 seconds). The infant has bilateral forehead wrinkling (video time 0:27 seconds). Her nasolabial creases on both sides are normal. Her tongue moves appropriately and sometimes protrudes (video time 0:24 seconds). She is able to move her neck throughout the clip. The accompanying photograph (Fig 1) shows the infant’s dilated right pupil that is fixed (ie, the pupil remains dilated even with bright light). As shown in Video 1, the infant’s right eye does not open spontaneously, and hence the eyelids had to be opened manually. The right eyeball is noted to be in the downward and outward location.
