Purpose: To evaluate the types, frequency, and causes of complications at the donor site after conjunctivo-limbal autograft for primary or recurrent pterygium treatment.
Methods: From January 2010 to December 2016, 91 eyes of 91 patients (male, n = 37; female, n = 54; mean age, 53.29 ± 10.73 years), diagnosed with primary or recurrent pterygium, and who were followed up for 6 months or longer after conjunctivo-limbal autograft, were enrolled in this study retrospectively.
Results: Of the 91 eyes, 27 eyes (29.7%) developed a conjunctival scar on the donor site and 36 eyes (39.6%) had localized vascularization. Eighteen eyes (19.8%) had a conjunctival scar and localized vascularization. Conjunctival granuloma and limbal stem cell deficiency occurred in one eye (1.1%). Multiple regression analysis showed that having a conjunctival scar and localized vascularization were significantly correlated with young age (p < 0.001), but were not significantly correlated with gender, pterygium type, dry eye, conjunctivochalasis, hypertension, diabetes, anticoagulant treatment, graft size, or delayed epithelialwound healing.
Conclusions: Conjunctival scarring or localized vascularization on the donor site after conjunctivo-limbal autograft for the treatment of the pterygium was found to be significantly higher in younger patients. Therefore, it is recommended that conjunctivo- limbal autograft should be adequately explained for donor-site complications in younger-aged pterygium patients.
