Ultrasonographic measurement of upper eyelid thickness in Korean children with epicanthus.

Lee HS, Lew H, Yun YS - Korean J Ophthalmol (2006)

Bottom Line: Upper eyelid thickness was measured to determine whether there is a difference in the thickness of the upper eyelids in children with and without epicanthus.The children with epicanthus were classified into four subgroups according to the Duke-Elder's classification.This result suggests that the etiology of epicanthus may not be hypertrophy of soft tissue.

ABSTRACT

Purpose: Upper eyelid thickness was measured to determine whether there is a difference in the thickness of the upper eyelids in children with and without epicanthus.

Methods: Children were enrolled into the epicanthus group or non-epicanthus (control) group. The children with epicanthus were classified into four subgroups according to the Duke-Elder's classification. The thickness of the upper eyelid was measured at five points with A-scan ultrasonography.

Results: There was no significant difference in upper eyelid thickness between the epicanthus group and control group (P > 0.05) or between the subgroups of the epicanthus group (P > 0.05).

Conclusions: This result suggests that the etiology of epicanthus may not be hypertrophy of soft tissue.

Mentions: The anterior segments of the eyes were examined with a slit-lamp to rule out the possibility of conjunctival inflammation, swelling, or a mass, that may change the thickness of the upper eyelid. The thickness of the upper lid was measured in mm by A-scan ultrasonography with a 10.0 MHz probe (A/B scan system, Humphrey instruments, INC., USA) (Fig. 2, 3). Three measurements were taken at each of five points by one investigator and the average values were used for data analysis. The five points of measurement in the upper lid were as follows; first point (I) - 3 mm upper point above the ciliary line on the middle line of the horizontal eyelid, second point (II) - 3 mm upper point on the superior border of tarsal plate on the middle line of the horizontal eyelid, third point (III) - 3 mm lower point below the orbital rim on the middle line of the horizontal eyelid, fourth point (IV) - 3 mm upper point above the ciliary line at the medial canthal lid margin, fifth point (V) - 3 mm upper point above the ciliary line at the lateral canthal lid margin.
