난치성 괴사성 공막 천공 환자에서 자가 귀구슬 연골막을 이용한 안구재건술 1예

초록

Purpose: To report the effectiveness of an autologous tragal perichondrium graft for a necrotizing scleritis case which was refractory to conventional surgery. Case summary: A 75-year-old woman was referred to our clinic with recurrent necrotizing scleritis of the left eye which occurred after pterygium removal five years earlier. The patient underwent scleral graft, pericardium graft, and amniotic membrane graft in other clinics; however, necrosis of the sclera progressed. The best corrected visual acuity was 0.06,and choroidal tissue was nearly exposed below the melted pericardium graft in the nasal area. The authors harvested tragal perichondrium from the right ear, and the scleral defect was successfully reconstructed with an autologous tragal perichondium graft. The graft showed rapid epithelization and neovascularization within a week and conjunctivalization after three months. No complications have been observed up to one year after surgery. Conclusions: Autologous tragal perichondrium graft is an effective treatment to alter necrotized sclera via neovascularization and rapid epithelization in refractory necrotizing scleritis cases.
