ABSTRACT

The treatment of glaucoma has varied through the years. Sclerothalamotomy is a surgical approach that seeks to create a thalamus through the trabecular mesh for the aqueous humor to circulate. Several devices are available to observe the esclerocorneal angle, such as OCT Visant, which is a coherent tomographic, biomicroscopic optical devise. This paper discusses the results found with such devise (OCT Visant), reviewing the anatomical changes caused by the surgery, as well as the creation of a cyclodialysis or a thalamus. The post-op sclerothalamotomy patients show anatomical changes in the architecture of the sclerocorneal angle induced by such surgical procedures. These changes have been analyzed by the OCT Visant and in each image of the sclerocorneal angle, one finds cyclodialysis and not thalamuses. In every image produced by the OCT Visant we find a split of the ciliary body of the iris (cyclodialysis) but not a thalamus. We may conclude that sclerothalamotomy is an attempt to create a thalamus in the t rabecular mesh. Yet, such thalamus is not viable and this surgical procedure causes a split of the iris or its roots (cyclodialysis).
