Background: Pterygium is a wing-shaped fibrovascular tissue overgrowth of the conjunctiva that crosses over the nasal or temporal limbus, or both, and grows onto the corneal surface. We report a case of complications due to the use of cyanoacrylate glue in conjunctival grafting in pterygium surgery.

Case presentation: A 70-year-old Iban woman presented with worsening foreign body sensation in the nasal aspect of the left eye 10 years after undergoing nasal pterygium excision. The foreign body sensation had worsened over the course of 1 year. Upon examination, a greyish foreign body in the nasal aspect of the left eye
(acrylate-like material) was noted.

Conclusion: In this case report, we highlight the complications of the usage of cyanoacrylate glue in pterygium surgery and the possible intraoperative complications in this case.
