Exophthalmia is a medical condition wherein the eyes are bulging out of their sockets. This condition can be caused by various factors such as hyperthyroidism, Graves' disease, or orbital tumors. Synonyms for exophthalmia include proptosis, bulging eyes, or exorbitism. Proptosis is a term commonly used by medical professionals to describe the forward displacement of the eyes. Exorbitism is another synonym, which also refers to the protrusion of the eyeballs out of the eye sockets. Both words are used interchangeably with exophthalmia and are derived from the Greek words "ex" meaning out and "ophthalmos" meaning eyes. Understanding these synonyms can help in communication between healthcare providers and patients when discussing the condition.
