A study of the various etiologies and sequelae to ectropion and entropion

Abstract

Purpose: This study aims to analyze the different etiologies of ectropion and entropion and helps in understanding the anatomical abnormalities responsible for the occurrence of entropion and ectropion, which is key to planning a successful surgical procedure. Methodology: It is a prospective study of 40 patients with ectropion and entropion studied for 17 months. Detailed slit lamp examination of lid abnormality, keratinization, trichiasis, corneal exposure was performed and axial length was measured. Results: The prevalence of ectropion and entropion put together was 0.064%. Paralytic ectropion ranks first among the different etiologies occupying 65.38%. The senile cause is the highest (78.57%) among the etiologies of entropion. The mean axial globe length of affected eyes in senile ectropion is 21.96 mm and in senile entropion is 20.73 mm. Conclusion: Eyelid malpositions have a low prevalence of 0.064%. The difference in the mean axial globe length between senile ectropion and entropion for this small sample size was found to be statistically significant. The overall percentage of conjunctival and corneal complications was found to be significantly higher in ectropion than in entropion.
