Bulging eyes, or proptosis, occurs when one or both eyes protrude from the eye sockets due to space taking lesions such as swelling of the muscles, fat, and tissue behind the eye. This causes more of the cornea to be exposed to air, making it more difficult to keep eyes moist and lubricated. In extreme cases, bulging eyes can create a large amount of pressure on the optic nerve, potentially leading to vision loss.
Often prominent eyes are mistaken for bulging eyes. Prominent eyes are generally hereditary and in most cases are harmless. However, bulging eyes can be a different case, as they may be linked to a more serious condition.
What Causes Bulging Eyes?
Bulging eyes have been linked to a number of diseases and conditions, including glaucoma, hyperthyroidism, leukemia, and more.
The most common cause of bulging eyes is Graves’ disease, or more specifically, Graves’ ophthalmopathy – an autoimmune condition where the thyroid gland mistakenly senses harmful cells and releases antibodies, which then fuse to eye muscles and cause inflammation.
Symptoms of Bulging Eyes
Bulging eyes are usually a symptom of another condition. Symptoms of Bulging eyes may include:
Appearance of protruding eyes
Excessive dryness in eyes
Visible whiteness between the top of the iris and the eyelid
Treatment for Bulging Eyes
The underlying cause of bulging eyes will determine the overall course of treatment. However, in all cases, bulging eyes will be exposed to more air making it difficult to keep them lubricated. To combat excessive dryness, artificial tears and eye drops can be used for moisture and lubrication.
