It is caused by vertical nystagmus, which is usually a congenital developmental abnormality due to involuntary periodic contraction of one, or more, of the superior rectus, inferior rectus, superior oblique, and inferior oblique muscles in the extraocular muscles, triggering the eyes to constantly turn in the vertical direction. 2. It is caused by tic disorder, which is usually prevalent in The symptoms will disappear naturally as most patients grow older. 3. It is caused by keratoconjunctival dryness, which is caused by a decrease in eye tear secretion, resulting in dry eyes without sufficient tear coverage on the surface of the eye.
