This study was conducted to examine the usefulness of limbal autograft transplantation in the treatment of recurrent and advanced pterygia.
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.
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.
These results indicate that limbal autograft transplantation may be effective for the treatment of recurrent and advanced pterygia.
本研究旨在探讨自体角膜缘移植术治疗复发性及进展性翼状胬肉的有效性。
11例复发性翼状胬肉患者和16例进展性翼状胬肉患者（共27只翼状胬肉）接受了自体角膜缘移植术。切除翼状胬肉后，取上方角膜缘组织并带结膜瓣转移至切除区域。
所有移植物均及时植入，供体部位重新上皮化，无过多瘢痕组织形成。虽然2只眼（7.4%）出现轻微复发，但结膜下组织侵犯局限于1mm以内，无需进一步手术干预。
这些结果表明自体角膜缘移植术可能对复发性及进展性翼状胬肉的治疗有效。
