Abstract:
The aqueous bumor makes an important role to maintain intraocular pressure. The production and outflow of aqueous humor controls the intraocular pressure. The accurate understanding of the pathway of aqueous outflow and the rate of outflow is essential to the study of glaucoma. The purpose of this study is to investigate the pathway of aqueous outflow after injection of dye into the anterior chamber, the duration of staining and the degree of delay of aqueous outflow after the use of viscoelastics. Three dyes. Gentian Violet, Methylene Blue and Viscoelastics mixed with Gentian Violer were injected into the anterior chambers of 20 eyes of 10 rabbits. The eyes were enucleated at 1 hour, 2 hour, 3 hour, 4 hour after injection of Gentian Violer and Methylene Blue. After injiection of viscoelastics mixed with Gentian violet, the eyes were enucleated at 2 hour, 4 hour, 6 hour, 8 hour, and 9 hour. The enucleated eyes were performed for frozen section and the fragments were observed by light microscopee. Gentian violet and Merhylene Blue were stained in the pathway of the pectinate ligaments, trabecular meshwork, intrascleral plexus and the pathway of the capillary network of iris and suprachoroidal space. The disappearance of injected dye was ended between 3 hour and 4 hour. And the viscoelastics mixed with dye was removed between 8 hour and 9 hour. This means that viscoelastics make the outflow of aqueous delay.
