Methods: A 47-yea r-old man underwent trabeculectomy because of elevated IOP. A specimen obtained during surgery was studied by transmission electron microscopy. Results: Electr on microscopy showed the presence of a monolayer composed of corneal endothelium -like cells and thick basement membrane-like material. Neovascularization was also observed in the corneoscleral trabeculum. Conclusions: Our results indicate that several mechanisms, including the formation of basement membrane-like tis sue, infiltration of inflammatory cells and neovascularization, might contribute to the elevation of IOP in Chandler’s syndrome. These may occur even when ther e is no history of conspicuous inflammatory reaction in the anterior ocular segm ents.展开更多
