intercanthal distance
Measurement between the inner corners of the eyes, used to assess orbital positioning and spacing.
Full Definition
A key anthropometric measurement representing the distance between the medial canthi (inner corners) of the eyes, commonly used in craniofacial surgery to evaluate orbital hypertelorism or hypotelorism. Normal intercanthal distance varies with age and ethnicity, with standardized norms available for comparison. This measurement is crucial in planning orbital repositioning surgeries and assessing treatment outcomes in patients with craniofacial syndromes or traumatic orbital injuries.
Usage
Usage note: Do not confuse with interpupillary distance, which measures between pupil centers rather than inner canthi.
In Context
- "The patient's intercanthal distance was 45mm, indicating moderate hypertelorism." — Clinical measurement
- "Post-operative intercanthal distance measurements showed successful orbital medialization." — Surgical outcome assessment
