| Abstract |
|
During filtration surgery for glaucoma, the conjunctival incision site is sutured watertightly with a suture material like 10-0 nylon. However, this suture material may cause the infiltration of inflammatory cells, and the proliferation and migration of fibroblasts and collagen fibers at the junction of the conjunctiva and episclera. Subsequently, the arrangement of collagen fiber in episclera would be disrupted and the outflow of aqueous humor could be occluded. In the search for a more suitable suture material, the fibrin glue(Tisseel(R)) was introduced recently. It is claimed to be simple to use and safe, causes less damage and less inflammatory reaction than nylon. The authors used 10-0 nylon(control group) on the right eye and fibrin glue(Tisseel(R))(experimental group) on the left eye of a white rabbit's conjunctival suture. We compared and evaluated the clinical and histological effects of the suture material on the suture site as well as on the intraocular region. The results were as follows; 1. In the experimental group, conjunctival injection and chemosis were mild and disappeared rapidly. 2. The filtering bleb was macroscopically well formed and maintained from the third postoperative day in both groups, but, thereafter, it decreased in size in two cases of the control group. 3. There was no difference in the inflammatory reaction in anterior chamber in both groups postoperatively. 4. In the experimental group, there was loosening of the fibroblasts proliferation and lesser infiltration of inflammatory cells at the postoperative second and fourth week. And the arrangement of collagen fibers in episclera was intact. The above findings strongly suggest fibrin glue(Tisseel(R)) as a suture material in the filtration surgery of glaucoma is clinically promising. |
