what causes eyes to pop out
Bulging of one eye, especially in a child, is a very serious sign. It should be checked right away. Hyperthyroidism (particularly Graves disease) is the most common cause of bulging eyes. With this condition, the eyes do not blink often and seem to have a staring quality. Normally, there should be no visible white between the top of the iris (the colored part of the eye) and the upper eyelid. Seeing white in this area most often is a sign that the eye is bulging.
