acorea
Definition
Noun: - Absence of the pupil in an eye: A medical condition where the pupil, the central opening in the iris of the eye, is congenitally missing.
Usage
- Medical Diagnosis: The term is used specifically in medical contexts, particularly in ophthalmology and clinical descriptions, to describe a rare anatomical anomaly.
- Formal/Technical Writing: It is found in medical textbooks, journals, and patient records.
Examples
- The ophthalmologist's report noted a congenital anomaly of acorea in the patient's left eye.
- Acorea is often associated with other severe developmental eye disorders.
Advanced Usage
- The condition is typically mentioned alongside other ocular malformations, such as microphthalmia (abnormally small eye) or anterior segment dysgenesis.
Variants and Related Words
- Corectopia (n): Displacement of the pupil from its normal central position.
- Aniridia (n): Partial or complete absence of the iris, which surrounds the pupil. (Note: This is a related but distinct condition from acorea).
Synonyms

- Congenital pupil absence (n): A more precise descriptive term.
Notes
- Etymology: Derived from Greek (meaning "without") and (meaning "pupil").
- Specificity: This term refers only to the absence of the pupil itself, not the surrounding iris. It is a very specific and rare clinical finding.
