Corneo-scleral graft is used in this study as an alternative material for its desirable properties of being transparent, higher in tensile strength, cheap and more readily available. Methods: Eighteen consecutive cases were implanted with the Ahmed glaucoma valve im-plant. The limbal portion of the silicone tube was covered by a comeo-scleral graft obtained from the corneo-scleral rim left over following corneal transplant operation. The effectiveness in protecting the tube from erosion or migration, the transparency of the patch graft and complications encountered after surgery were assessed.Results: At a mean follow-up of 6 months, all tubes were well protected and no complications related to the patch graft were encountered during intra and postoperative period. All comeo-scleral grafts remained transparent and展开更多

Various surgical methods were explored to treat such patients. However, there is no defined protocol. The aim of this study was to describe a new combined operation, and to demonstrate the outcome of the treatment. Methods Nine patients with BAE were enrolled in our study. The combined operation including pars plana vitrectomy （PPV）, sclera patch graft （SPG） and endoscopic cyclophotocoagulation （ECP） was used to treat these patients. Results In the follow-up of 18-24 months, all patients with the endophthalmitis were cured, the useful visual acuity was preserved in 7 patients, and the intraocular pressure （lOP） of 8 patients was controlled just after first operation, only one needed another trans-scleral cyclophotocoagulation. Conclusion This combined operation is a useful method for treating the patients with BAE, with SPG and vitrectomy to control the endophthalmitis and ECP to balance the postoperative lOP.展开更多
