Eyes, Widely Spaced

Definition:

Objective: Interpupillary distance more than 2 SD above the mean (newborns 27-41 weeks gestational age) OR Interpupillary distance above the 97th centile (0-15 years of age)

Subjective: The interpupillary distance appears to be increased

Comments:

The finding is measured according to Hall et al. [2007]. Note that the data from Hall et al. [2007] show continuing increase in this measurement between 14 and 15 years of age, so this finding should only be made according to the subjective definition in persons above 15 years of age. It is important to distinguish between truly increased interpupillary distance and the apparently increased spacing that is caused by Telecanthus (see that entry for additional discussion). See Figure 3 for an illustration of variations of eye spacing.

Synonyms:

• Hypertelorism
