exophthalmos
Học thuậtThân thiện
Definition
Noun: A medical condition characterized by an abnormal protrusion or bulging of the eyeball(s) from the eye socket (orbit). It is often a symptom of an underlying disease, most commonly thyroid eye disease (Graves' ophthalmopathy).
Usage
This is a specialized medical term. It is used in clinical, diagnostic, and academic contexts to describe the physical sign of protruding eyes.
Examples
- The patient's exophthalmos was a clear indicator for further thyroid function tests.
- Severe exophthalmos can lead to difficulty closing the eyelids and corneal exposure.
- The doctor noted bilateral exophthalmos during the examination.
Advanced Usage
- Adjectival Form: The condition can be described using the adjective exophthalmic, as in "exophthalmic goiter."
- Measurement: The degree of protrusion is often measured in millimeters using an instrument called an exophthalmometer.
- Unilateral vs. Bilateral: The term specifies whether one eye (unilateral exophthalmos) or both eyes (bilateral exophthalmos) are affected, which aids in differential diagnosis.
Variants and Related Words
- Exophthalmus: An alternative, less common spelling.
- Proptosis: In clinical practice, this term is often used interchangeably with exophthalmos, though some specialists distinguish proptosis as a more general term for any forward displacement of the eye.
- Exophthalmic (adj): Pertaining to or characterized by exophthalmos.
