Background And Objective:
This study was conducted to examine the usefulness of limbal autograft transplantation in the treatment of recurrent and advanced pterygia.
Patients And Methods:
Eleven patients with recurrent and 16 with advanced pterygia (a total of 27 pterygia) were treated with limbal autograft transplantation. Once a pterygium had been excised, superior limbal tissue was taken with conjunctival flap and transferred to the excised area.
Results:
All the grafts were planted promptly, and donor sites were re-epithelialized with no excessive scar tissue formation. Although slight recurrence was noted in 2 eyes (7.4%), subconjunctival tissue invasions were limited to less than 1 mm, and no further surgical interventions were needed.
Conclusion:
These results indicate that limbal autograft transplantation may be effective for the treatment of recurrent and advanced pterygia.
