Effect of Sleep Position on the Development of Ectropion or Entropion in Aged Population

Abstract

Purpose: To explore a potential correlation between the position of the head of a sleeping individual and the (presence) of a unilateral ectropion or entropion. Method: A retrospective case series. Data were collected from all patients who had undergone repair of an involutional ectropion or entropion between 2004 and 2017 from all causes at the Soroka University Medical Center. Results: Thirty-six patients were available for participation in the survey received a telephone questionnaire regarding their sleep position and preference. The questionnaire was aimed to determine the patient's quality of sleep, position, and side preference while asleep. The ectropion group includes 16 patients who have had a statistically significant positive association between the preference of a head posture during sleep and the development of a unilateral ectropion (χ=6.11, p<0.05). There was no statistically significant correlation between head position preference and entropion occurrence. Conclusions: This study firstly demonstrates the correlation between sleep position preference and the risk of developing an involutional ectropion.
