Purpose. Cyclectomy/trabeculectomy and Ahmed glaucoma valve implant are operations suggested for refractory glaucomas. In this study, we have evaluated the outcomes that we observed with these two techniques in neovascular glaucoma patients. Material and Methods. Thirty-five eyes with neovascular glaucomas were included in this study. Ahmed Glaucoma valve (group A) was applied to ten eyes, while cyclectomy/trabeculectomy was applied to 25 eyes (group C/T). Vision, intraocular pressure and complications were evaluated at the end of the first week and after 6 and 12 months. Results. Vision preservations were 80% and 92%, and success rates in reducing intraocular pressure were 50% and 72% for Ahmed glaucoma valve and cyclectomy/trabeculectomy groups, respectively. None of the differences in complication rates was found to be statistically significant. Conclusions. In the surgical management of neovascular glaucoma, cyclectomy/trabeculectomy was shown to be an alternative to Ahmed glaucoma valve operation.

Objective: The aim of this study was to develop an experimental model for the assessment of bone augmentation, and in doing so, compare the use of beta-tricalcium phosphate (TCP) bone grafts in combination with Gore-Tex augmentation material (GTAM) and GTAM without TCP., Method and Materials: Calvarial sites in eight Sprague Dawley rats were prepared for bone augmentation. Graft materials and Hermann stainless steel bone pins were used for localized bone augmentation. Specimens were subjected to macroscopic and histological evaluation at the sixth week., Results: Bone formation was significantly higher in the group with the graft support., Conclusion: TCP bone grafts used in conjunction with supporting pins may contribute to successful bone regeneration by osseoconduction and by maintaining the membrane-created space. At the sixth week, guided bone regeneration utilizing Gore-Tex augmentation material and TCP bone grafts resulted in the formation of viable new bone.
