The study aims to compare the effectiveness and complications of transconjunctival retractor plication (TRP) with lateral tarsal strip (LTS) and the polypropylene sling (PS) surgery for treatment of involutional lower lid ectropion.
A prospective randomised pilot study was conducted on 30 eyes of 30 patients suffering from epiphora having horizontal eyelid laxity >6mm and age >50 years at a tertiary care centre from December 2014 to March 2015. They were randomly divided into two equal groups for TRP with LTS (group A) and PS (group B). Success was defined as relief in epiphora and lid laxity ≤4mm at 12 months post operatively.
There were 19 male and 11 female patients with age ranging from 55-80 years. The mean grade of ectropion was 2.80±1.32 in group A and 2.87±1.60 in group B. The preoperative horizontal laxity increased with the grade of ectropion (p <0.001) while medial canthal laxity was variable. The average surgical time per procedure in group A was 66 minutes and in group B was 24 minutes. Group A had a success rate of 93.33%, while group B had a success rate of 87%. Post-operative complications occurred in 2 eyes in group B only.
Both LTS with TRP and PS are effective in the management of involutional ectropion. LTS with TRP though more invasive has higher success rates and a lower incidence of complications as compared to PS. However, PS is an easy to perform out- patient procedure that is faster and better tolerated in old patients.
