This article describes a novel surgical technique for successful repair of intractable corneoscleral necrosis caused by severe ocular burns. In this prospective case series, 19 eyes of 15 consecutive patients with sectional scleral necrosis and persistent corneal epithelial defects were treated with tenonplasty and amniotic membrane transplantation. The main outcome measure was the stability of the ocular surface after reepithelialization and repair of defects. All patients underwent successful combined surgery involving tenonplasty and amniotic membrane transplantation, in which the conjunctival and corneal surfaces were reconstructed. The interval from injury to surgery was 37.4 ± 24.5 days (3-91 days), and the ocular surfaces became stabilized in 82.2 ± 35.4 days (26-156 days, median 87 days). At the final visit, all cases presented with corneal opacity and neovascularization to various degrees. The best-corrected visual acuity decreased from 2.83 ± 1.02 LogMAR preoperatively to 2.87 ± 1.31 LogMAR postoperatively. The results imply that tenonplasty combined with amniotic membrane transplantation could provide vascular supply to the ischemic sclera, repair defects in the conjunctiva, and promote corneal reepithelialization, thus facilitating ocular surface stabilization after burns.
