Proptosis (rare plural: proptoses) refers to forward protrusion of the globe with respect to the orbit. There are many causes of proptosis which can be divided according to location and it is worth remembering that it is not just orbital disease processes that cause proptosis
Remember the main causes of Proptosis using the mnemonic THE-I (pronouned THE-EYE).
THE I (I~eye)
- Tumor (eg, retinoblastoma)
- Hemorrhage (eg, traumatic posterior orbital hematoma)
- Endocrinopathy (eg, Graves’ disease)
- Infection (eg, orbital cellulitis
Another mnemonic to remember the causes of Proptosis is VEIN.
