A Comparative Analysis of the Clinical Outcomes of Two Surgical Techniques for the Treatment of Senile Lower Eyelid Entropion with Trichiasis

This study investigates the clinical efficacy of different surgical methods for treating senile entropion with trichiasis of the lower eyelid and their effectiveness in alleviating symptoms.A total of 54 cases of elderly patients with senile entropion and trichiasis of the lower eyelid were included as study subjects. They were divided into a control group (30 cases, 46 eyes) treated with eyelid skin and orbicularis oculi muscle excision, and an observation group (24 cases, 40 eyes) treated with orbicularis oculi muscle shortening combined with marginal inversion suture.The clinical efficacy of the two groups was compared, and improvements in ocular symptoms were assessed using specialized scales.Results: Both groups demonstrated high surgical efficacy with no statistically significant difference (P>0.05). The observation group exhibited higher tear film breakup time (BUT) and tear meniscus height (TMH), and lower corneal fluorescein staining (CFS) and ocular surface disease index (OSDI) scores compared to the control group. These differences were statistically significant (P<0.05).The incidence of postoperative complications was low in both groups, with no statistically significant differences (P > 0.05).For elderly patients with lower eyelid entropion, the procedure of orbicularis oculi muscle shortening combined with marginal inversion suture can achieve definitive clinical efficacy and significantly alleviate ocular discomfort.
