線維柱帯切除術後の濾過胞からの房水漏出に対する結膜移植術の治療成績

Outcome of conjunctival transplantation for leaking bleb after trabeculectomy

　線維柱帯切除術後に濾過胞から房水漏出（bleb leak）が3眼に生じ，結膜移植を行った。1例は線維柱帯切除術2年後に房水漏出が生じ，有茎結膜弁で濾過胞を被覆した。術後に結膜縫合不全が起こり，再縫合を要した。1例は外傷で房水漏出が起こり，濾過胞を切除し有茎結膜弁移植を行った。他の1例は線維柱帯切除術27か月後に房水漏出が起こり，濾過胞の切除と結膜移植を行った。第2例と第3例では術後に短期間の結膜漏出があった。全例で房水漏出の再発はなく，眼圧の経過も良好であった。

　Three eyes were treated by conjunctival transplantation for leaking bleb following trabeculectomy. One case developed leaking bleb 2 years after trabeculectomy. The bleb was repaired by pedunculated conjunctival flap. Resuturing became necessary for insufficient conjuntival repair. A second case developed leaking bleb after trauma. The bleb was excised and covered by pedunculated conjunctival flap. A third case developed leaking bleb 27months after trabeculectolmy. The bleb was excised and covered by a conjunctival flap. The last two cases developed short-term leakage through the transplanted conjunctiva. Eventual cure was obtained in all cases with well-controlled intraocular pressure.
