sunset eyes?

What is the context? Sunsetting eyes can be a sign of increased pressure in the brain, often from hydrocephalus. But context would be helpful.

there is a baby who has "sunset eyeball" movements. he also has been dx with severe hypoxic ischemic encephalopathy and an intraventricular germinal matrix hemorrhage....from what i can tell they are related somehow. i looked up the last 2 and have an understanding of what they mean....but sunset eyes is still throwing me. does it go away if the pressure in the brain decreases or is it permanent? don't worry....i will enlist the help of a physician who will review the medicals...but in the meantime i knew that if someone here had a child with sunset eyes or had any knowledge to impart i would find it helpful. :)
