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 epicanthus patients were classified into four groups according to Duke-Elder's classification (Fig. 1A).2,4 In epicanthus supraciliaris the epichanthal fold arises from the region of the eyebrow and runs toward the tear sac or the nostrils. In epicanthus palpebralis the epicanthal fold arises from the upper lid, above the tarsal region, and extends to the lower margin of the orbit (Fig. 1B). In epicanthus tarsalis the epicanthal fold arises from the tarsal fold and is lost in the skin close to the inner canthus (Fig. 1C). Epicanthus inversus differs greatly from the first three cases, with a small epicanthal fold arising in the lower eyelid and extending upward, partially covering the inner canthus (Fig. 1D).
