Eyes - bulging

Protruding eyes; Exophthalmos; Proptosis; Bulging eyes

Bulging eyes is the abnormal protrusion (bulging out) of one or both eyeballs.

Considerations

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.

Hyperthyroidism (particularly Graves disease) is the most common medical 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.

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

Causes may include:

Home Care

The cause needs to be treated by a provider. Because bulging eyes can cause a person to be self-conscious, emotional support is important.

When to Contact a Medical Professional

Contact your provider if:

  • You have bulging eyes and the cause has not yet been diagnosed.
  • Bulging eyes are accompanied by other symptoms, such as pain or fever.

The provider will ask about your medical history and do a physical exam.

Some questions you may be asked include:

  • Are both eyes bulging?
  • When did you first notice bulging eyes?
  • Is it getting worse?
  • What other symptoms do you have?

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).

    Goiter - illustration

    A goiter is a swelling in the neck due to an enlarged thyroid gland. The size may range from a single small nodule to a large neck lump. The swollen thyroid can put pressure on the windpipe and esophagus which can cause a cough, wheezing, breathing difficulties or swallowing difficulties. A goiter only needs to be treated if it is causing symptoms.
