Conjunctiva-limbus autografting is known as a safe surgical technique for the removal of pterygia, with a low rate of recurrence. However, the long-term effect of this surgical maneuver is not clear. This study now investigates the long-term efficacy of conjunctiva-limbus autografts to prevent pterygium recurrence.
Conjunctiva-limbus transplants for primary (n = 62) or recurrent (n = 8) pterygia were reevaluated 11 to 83 months after surgery (mean: 44.97 months). Slit-lamp appearance and photomicrographs were studied with respect to the configuration of the transplant and the recurrence of the fibrovascular tissue typical of pterygia.
Corneal pterygium recurrence has been observed in 2 cases. Fibrovascular tissue was found at the peripheral transplant-margin in 15 cases, and transplant compression towards the limbal margins were detected in further 7 patients. These conjunctival changes have not been observed during the first postoperative months.
Conjunctiva-limbus autografts in pterygia have excellent efficacy against recurrence within the first few years. The transplant compression and fibrovascular changes within the peripheral conjuctiva seen in this study suggest that recurrencies might, however, develop on the long-term.
结膜-角膜缘自体移植术是一种已知的用于切除翼状胬肉的安全手术技术，复发率较低。然而，这种手术操作的长期效果尚不清楚。本研究现调查结膜-角膜缘自体移植术预防翼状胬肉复发的长期疗效。
对原发性（n = 62）或复发性（n = 8）翼状胬肉的结膜-角膜缘移植术后11至83个月（平均：44.97个月）进行重新评估。通过裂隙灯外观和显微照片研究移植片的形态以及翼状胬肉典型的纤维血管组织复发情况。
观察到2例角膜翼状胬肉复发。15例在周边移植片边缘发现纤维血管组织，另有7例检测到移植片向角膜缘边缘的压迫。这些结膜变化在术后最初几个月未观察到。
翼状胬肉的结膜-角膜缘自体移植术在最初几年对预防复发具有优异疗效。然而，本研究中观察到的周边结膜内的移植片压迫和纤维血管变化表明，从长期来看可能会出现复发。
