Involutional entropion and ectropion of the Asian lower eyelid.

PURPOSE
A clinical observation showed that involutional entropion of the lower eyelid in Asians may occur more commonly than ectropion. A review of surgical cases was performed to examine this hypothesis.


METHODS
A retrospective review of the number of Asian lower lid involutional ectropion and entropion repairs was performed in three different clinical practice settings. These data were compared and statistically analyzed with similar data for non-Asian patients.


RESULTS
The frequency of ectropion among Asians was significantly less than in non-Asians (chi-square, p < 0.001). Asian entropion repair represented 11.4% of the 604 eyelid operations performed on Asians, whereas Asian ectropion repair made up only 1.5% of cases. Non-Asian entropion and ectropion repairs were 3.7% and 6.2%, respectively, of the 1,849 eyelid procedures performed on non-Asians.


CONCLUSIONS
Because of the normal anteriorly protruding position of the orbital fat within the Asian lower eyelid, Asians may be more predisposed than whites to the development of involutional entropion rather than ectropion. Removal of lower eyelid fat should be considered in entropion repair of the Asian lower eyelid.
