Involutional Entropion and Ectropion of the Lower Eyelid: Prevalence and Associated Risk Factors in the Elderly Population

Abstract

The prevalence of involutional entropion and ectropion in the elderly population is 2.1% and 2.9%, respectively. The axial ocular globe position plays a pathogenic role in involutional lower eyelid malposition.

Eyelid aging: pathophysiology and clinical management

“…The prevalence of involutional ectropion seems to be similar to that of involutional entropion (12) . The literature suggests that the pre valence of ectropion is about 4% in patients older than 49 years, not differing among the different ectropion forms or regarding the underlying etiology (12,13) . This involutional malformation is the most common form of ectropion and entropion (14) .…”

“…In contrast, involutional entropion is more often seen in women (12) . This gender difference is caused by the difference in tarsal plate size and axial ocular globe projection between (12,15,16) . The involutional forms of ectropion and entropion affect whites more often than blacks (17,18) .…”

“…The involutional forms of ectropion and entropion affect whites more often than blacks (17,18) . The prevalence of involutional ectropion and entropion increases with the patient's age (12) , which is the logical order for involutional malformations to increase with age (13) .…”

“…This involutional malformation is the most common form of ectropion and entropion (14) . Males are more often affected by involutional ectropion (12) . In contrast, involutional entropion is more often seen in women (12) .…”
