Summary

The eyelid crease position in children varies with age. Infants and toddlers have a lower crease, while older children have a higher one, guiding surgical placement for indistinct creases.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology

Background:

  • Determining the normal upper eyelid crease position is crucial for surgical correction of ptosis or aesthetic enhancement in children.
  • Existing data on eyelid crease proportions in pediatric populations is limited, necessitating further investigation.

Purpose of the Study:

  • To establish normative measurements for upper eyelid crease (LC) to lower brow (LB) ratios in a pediatric cohort.
  • To investigate potential age-related differences in eyelid crease proportions among children.
  • To provide data to guide surgical placement of eyelid creases in pediatric patients.

Main Methods:

  • Measurements of lash-line-lid crease (LC), lash-line-lower brow (LB), vertical fissure, and horizontal fissure were taken in 33 children.
  • Data were analyzed for age-group differences (infants/toddlers vs. preschool/school-age) and demographic factors (race, sex).

Main Results:

  • The mean LC/LB ratio was 0.33, with no significant differences based on race or sex.
  • A statistically significant difference (P < .01) was observed in the mean LC/LB ratio between age groups.
  • Preschool and school-age children exhibited a significantly greater mean ratio compared to infants and toddlers.

Conclusions:

  • The normal eyelid crease position in children is approximately one-third of the distance from the lash line to the lower brow.
  • Eyelid crease position demonstrates age-specific variations, being lower in infants/toddlers and higher in older children.
  • Age-based normative data can inform surgical decisions for eyelid crease reconstruction in pediatric patients.
