The exact plural of Exophthalmos is exophthalmoses.
Exophthalmos, a medical term describing the forward protrusion of the globe (the eyeball), has a specific plural form derived from its Greek origin. While "exophthalmoses" is the grammatically correct plural, its usage is relatively rare in everyday medical conversation.
Understanding Exophthalmos
Exophthalmos (sometimes referred to as proptosis) is a condition where one or both eyeballs protrude from their normal position within the eye socket. This can be a symptom of various underlying medical conditions, most notably thyroid eye disease (Graves' ophthalmopathy), but also orbital tumors, inflammation, or trauma.
- Common Causes of Exophthalmos:
- Thyroid Eye Disease (Graves' Disease): The most common cause, where the immune system attacks the tissues and muscles around the eyes.
- Orbital Tumors: Benign or malignant growths behind the eye can push the globe forward.
- Inflammation or Infection: Conditions like orbital cellulitis can cause swelling and protrusion.
- Vascular Abnormalities: Abnormal blood vessel formations in the orbit.
For more detailed information on the condition, you can refer to resources like the American Academy of Ophthalmology.
The Plural Form: Exophthalmoses
The pluralization of "Exophthalmos" follows a pattern common in medical and scientific terminology, particularly for words of Greek origin ending in "-os." Just as "diagnosis" becomes "diagnoses" and "prognosis" becomes "prognoses," "Exophthalmos" becomes exophthalmoses.

Why is "Exophthalmoses" Rarely Used?
Despite being the technically correct plural, "exophthalmoses" is seldom heard in clinical settings or general discourse. Medical professionals often opt for alternative phrases to describe multiple instances of the condition. This is similar to how some other technically correct but less common plurals are avoided in favor of clearer, more direct language.
- Common Alternatives:
- "Cases of exophthalmos"
- "Multiple patients presenting with exophthalmos"
- "Instances of globe protrusion"
These phrases convey the same meaning while being more immediately understandable and less cumbersome for many speakers and writers. The rarity of the "exophthalmoses" plural reflects a broader trend in language to prioritize clarity and common usage, especially in specialized fields.
