목적: 공막연화증의 수술적 치료로 조직접합제를 이용한 공막이식술과 자유자가결막이식술 그리고 일시적 양막이식술을 시행한 후 임상결과를 알아보고자 하였다. 대상과 방법: 군날개절제술 후 발생한 공막연화증으로 수술적 치료가 필요한 20명 20안을 대상으로 조직접합제를 이용한 공막이식술과 자유자가결막이식술 그리고 일시적 양막이식술을 실시하고 1년 이상 경과관찰 하여 수술결과 및 합병증을 조사하였다. 결과: 술 후 평균 17.6 ± 5.9개월의 경과관찰 기간 동안 1예를 제외한 모든 경우에서 술 후 1개월째 결막이식편과 주위의 충혈 및 부종이 대부분 소실되었고, 술 후 3개월째 이식편은 성공적으로 생착되었다. 하지만 1예에서 부주의한 관리로 술 후 2주째 결막이식편이 부분 손실되었으나 적절한 치료를 통해 술 후 6개월째부터는 안정된 안구표면을 이루었다. 3예에서 술 후 6개월 이후 공막이식편의 가장자리가 부분적으로 흡수되었지만 안구표면은 결막이식편이 덮고 있어서 안정적으로 유지되었다. 결론: 공막연화증 환자에서 조직접합제를 이용한 공막이식술과 자유자가결막이식술 그리고 일시적 양막이식술은 안구표면의 안정화가 빠르고 미용적인 효과도 우수한 수술방법이 될 수 있다.
Abstract
Purpose: To evaluate the surgical results and complications arising from scleral graft and free conjunctival autograft using tissue adhesive and temporary amniotic membrane transplantation as the surgical treatment for scleromalacia. Methods: Scleral graft and free conjunctival autograft using tissue adhesive and temporary amniotic membrane transplantation was performed in 20 eyes of 20 patients with scleromalacia caused by pterygium excision. The surgical results and complications arising from the procedure were monitored and analyzed through follow-up. Results: During the follow-up period of 17.6 ± 5.9 months, the wound injection and edema at the free conjunctival autograft and operation site healed in all the cases except 1 at postoperative 1 month. The stability of the ocular surface for graft transplantation was maintained at postoperative 3 months. Although a partial absorption of the conjunctival autograft induced by careless treatment occurred 2 weeks postoperative in 1 case, the ocular surface stabilized due to suitable treatment after 6 months. Although the edges of the scleral graft in 3 patients were partially absorbed 6 months postoperatively, the ocular surface stability was maintained by covering the conjunctival autografts. Conclusions: For scleromalacia patients, scleral graft and free conjunctival autograft using tissue adhesive and temporary amniotic membrane transplantation rapidly stabilized the ocular surface and presented excellent aesthetic results.
