Abstract
A 40-year-old woman visited our clinic for recurred pterygium and symblepharon in the right eye. She had a history of pterygium excision 8 years before. Over the course of 7 years, we performed pterygium excision combined initially with mitomycin C (MMC) application and conjunctival autograft. This was followed by three procedures using limbal allografts, MMC application, and amniotic membrane transplantation. All procedures were unsuccessful, resulting in aggressive recurrences of pterygial mass and symblepharon, extraocular movement limitation, corneal astigmatism, and decreased visual acuity. Ultimately, we applied a labial mucosal autograft after the recession of pterygial tissue. No complications were observed. Two and a half years postoperatively, the labial mucosal autograft was well-integrated into the conjunctival surface without symblepharon recurrence or abduction limitation. Corneal clarity was restored, and astigmatism was reduced, with no recurrence of pterygium. In conclusion, a labial mucosal autograft is a viable treatment option in complex cases of recalcitrantly recurrent pterygium with symblepharon.
