Exophthalmus
A condition characterized by bulging of the eye anteriorly out of the orbit
Exophthalmus[edit | edit source]
Exophthalmus, also known as proptosis, is a condition where the eye bulges anteriorly out of the orbit. It is most commonly associated with thyroid eye disease, particularly Graves' disease, but can also result from other causes such as orbital tumors, inflammation, or trauma.
Causes[edit | edit source]
Exophthalmus can be caused by a variety of conditions, including:
- Graves' disease: An autoimmune disorder that affects the thyroid gland and is the most common cause of exophthalmus.
- Orbital tumors: Tumors within the orbit can push the eye forward.
- Inflammation: Conditions such as orbital cellulitis or sarcoidosis can cause swelling and displacement of the eye.
- Trauma: Injury to the orbit can lead to bleeding or swelling that displaces the eye.
Symptoms[edit | edit source]
The primary symptom of exophthalmus is the noticeable protrusion of one or both eyes. Other symptoms may include:
- Dry eyes or irritation due to exposure
- Double vision
- Eye pain or discomfort
- Redness and swelling of the eye and surrounding tissues
- Vision changes
Diagnosis[edit | edit source]
Diagnosis of exophthalmus involves a thorough clinical examination and may include:
- Visual acuity tests
- Ophthalmic examination
- Imaging studies such as CT scan or MRI to assess the orbit and surrounding structures
- Blood tests to evaluate thyroid function and detect autoimmune markers
Treatment[edit | edit source]
Treatment of exophthalmus depends on the underlying cause:
- For Graves' disease, treatment may include medications to control thyroid function, radioactive iodine therapy, or surgery.
- In cases of inflammation, corticosteroids or other anti-inflammatory medications may be used.
- Surgical intervention may be necessary to remove tumors or relieve pressure within the orbit.
Prognosis[edit | edit source]
The prognosis for exophthalmus varies depending on the cause and severity of the condition. Early diagnosis and treatment are crucial to prevent complications such as vision loss or corneal damage.
