What is the difference between proptosis and exophthalmos?
Proptosis can describe any organ that is displaced forward, while exophthalmos refers to only the eyes. Proptosis can include any directional forward displacement.
How do you assess for exophthalmos?
Diagnosing exophthalmos
- check how well you’re able to move your eyes.
- use an instrument called an exophthalmometer to measure how far your eyeball protrudes.
- arrange for a CT scan or MRI scan.
- arrange for a blood test to check how well your thyroid gland is working.
What is the difference between exophthalmos and Enophthalmos?
Proptosis can also be used for other viscera (although rarely seen in contemporaneous usage), but exophthalmos only for the eyes. Enophthalmos is the antonym, referring to displacement of the globe posteriorly.
What are the stages of thyroid eye disease?
There are two phases. The active phase, marked by inflammation, usually lasts from six months to two years. The focus during this stage is on medical treatment to relieve the eye symptoms. During the second phase, or the stable phase, inflammation and other symptoms have subsided.
What disease causes exophthalmos?
In adults, the most common cause of unilateral and bilateral exophthalmos is thyroid-associated eye disease, such as Graves-related ophthalmopathy. In children, orbital cellulitis is the most common cause, whereas bilateral exophthalmos is most likely due to neuroblastoma and leukemia.
When does exophthalmos occur?
Exophthalmos is the protrusion of one or both eyes anteriorly out of the orbit due to an increase in orbital contents within the rigid bony orbit. It most commonly manifests in thyroid-associated eye disease such as Graves’ disease ophthalmopathy.
How quickly does thyroid eye disease progress?
Eye problems will usually occur and frequently change in type or severity for between six months and two years. Once stabilized, it is unusual for the eyes to start changing again. Some patients are left with permanent changes, and in others the eyes return to normal.
Can exophthalmos be treated?
In some cases, surgery may be considered as a treatment for exophthalmos if you have severe or persistent symptoms. For example, surgery might be used to improve the appearance of your eyes if exophthalmos has been in the inactive phase for a few months.
What causes thyroid eye bulging?
Hyperthyroidism occurs when your thyroid releases too many of these hormones. An autoimmune disorder called Graves’ disease is the most common cause of hyperthyroidism and bulging eyes. In this condition, tissues around your eye become inflamed. This creates the bulging effect.
How does exophthalmos develop?
Exophthalmos typically arises from an increase in orbital contents within the bony orbit, leading to forward displacement of the globe. The origin of the increased orbital content depends on the underlying cause.
Is exophthalmos reversible?
For example, surgery might be used to improve the appearance of your eyes if exophthalmos has been in the inactive phase for a few months. However, medical treatment alone will not necessarily reverse the protrusion of the eyes.
What happens if thyroid eye disease goes untreated?
Thyroid eye disease in its active phase can last between one and three years. That means if it is left untreated, the inflammation may gradually decrease by itself but may cause damage to vision through the course of the disease.
