Trichiasis in cicatricial ocular surface disease: a multi-center comparison of electroepilation versus eyelash...

To evaluate the outcomes of trichiasis (excluding entropion) management in non-trachomatous cicatricial ocular surface diseases.

This is a multicenter, retrospective study of 59 patients with trichiasis who were managed using two different techniques: electroepilation using radiofrequency (RF) cautery and eyelash resection. The assessed outcomes were residual trichiasis at 6 weeks, 6, and 12 months of follow-up and the number of procedures needed.

41 patients (90 eyelids) underwent electroepilation, and 18 (41 eyelids) were managed with eyelash resection. All patients belonged to either Indian or Japanese ethnicity. Most patients in both groups had Stevens-Johnson Syndrome (63.4% vs. 88.9%). The mean age (43.2 vs. 46 years), disease duration (122 vs. 192.4 months), median trichiasis grade (2 vs. 2), and involvement of upper eyelids (53/90 vs. 23/41) were similar in the two groups. At six weeks, 48.9% of eyelids that underwent electroepilation had no trichiasis, and recurrences were managed with repeat electroepilation (6 eyelids) and mucous membrane grafting (10 eyelids), and 35 eyelids opted for manual epilation, giving 67.8% success at a mean follow-up of 20 months. The eyelash resection group had 75.6% success at 6 months, and recurrences were managed using lid splitting and eyelash resection, resulting in 100% success at a mean follow-up of 79 months. More interventions were needed in the electroepilation group compared to eyelash resection.

Eyelash resection of the trichiatic eyelashes achieves a better success rate than electroepilation in cicatricial ocular surface disorders. Following electroepilation, one needs multiple interventions to resolve trichiasis.
