Protruding eyes; Exophthalmos; Proptosis; Bulging eyes
Bulging eyes is the abnormal protrusion (bulging out) of one or both eyeballs.
Prominent eyes may be a family trait. But prominent eyes are not the same as bulging eyes. Bulging eyes should be checked by a health care provider.
Bulging of one eye, especially in a child, can be a very serious sign. It should be checked right away.
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.
Because eye changes most often develop slowly, family members may not notice it until the condition is fairly advanced. Photos often draw attention to the bulging when it may have gone unnoticed before.
Causes may include:
The cause needs to be treated by a provider. Because bulging eyes can cause a person to be self-conscious, emotional support is important.
Contact your provider if:
The provider will ask about your medical history and do a physical exam.
Some questions you may be asked include:
A slit-lamp examination may be done. Blood testing for thyroid disease may be done.
Treatments depend on the cause. Artificial tears may be given to lubricate the eye to protect its surface (cornea).
