Younger Age-Related Incidence of Corneal Limbitis Following Pterygium Excision Combined with Conjunctival-Limbal Autograft

<p>To investigate the incidence, clinical characteristics, and risk factors of corneal limbitis following pterygium excision with conjunctival-limbal autograft.</p> <p>This retrospective study included 63 eyes of 61 patients with primary nasal pterygium who underwent pterygium excision with conjunctival-limbal autograft. Patients were assessed perioperatively using anterior segment swept-source optical coherence tomography (AS SS-OCT; Anterion, Heidelberg, Germany), and postoperative complications were evaluated during follow-up.

Risk factors for corneal limbitis, including age and preoperative AS SS-OCT-guided morphological and optical parameters, were analyzed.</p> <p>Corneal limbitis occurred in 12 of 63 eyes (19.0%), with a mean onset of 19.1 ± 10.9 weeks postoperatively. Eyes with limbitis were significantly younger than those without (45.3 ± 8.1 vs. 60.5 ± 9.5 years, <i>p</i> < 0.001), while other demographic, clinical severity, and morphological parameters were not significantly different between the two groups.
