A Review of Eyelid Margin Malpositions: A Unique Spectrum in a South-East Asian Tertiary Hospital

Abstract

This study shows that the spectrum of eyelid margin malpositions in Singapore is unique and that developmental epiblepharon remains the commonest eyelid margin malposition requiring surgery. In terms of involutional eyelid margin malpositions, entropion is more common than ectropion, especially among the Chinese. The similarity in terms of eyelid involvement and ethnic distribution of both epiblepharon and involutional entropion suggests that there is a common factor in both these conditions, which the authors infer is due to the unique anatomy of the Asian eyelid.

“…24,26 It is also unique regarding the type of population, namely Caucasian and Latin subjects, compared with Chinese, 25 Japanese, 17 Pakistani 26 or Bangladeshi 7 subjects in the prior studies. Previous studies have already reported the anatomical differences between oriental and occidental population, 27,28 something that makes difficult the extrapolation of the results from one ethnics to others.…”
