Abstract

The scleral attachments of the ciliary body and choroid were found to be densest from the equator to the posterior pole, less dense at the ora serrata, and practically nonexistent under the ciliary body and between the ora and equator. The elasticity of the choroid is such that in the excised human eye about 2 mm. Hg pressure is necessary to distend the uvea against the sclera. The tensile strength of the choroid was found to be greater than 5 Gin. per centimeter. It was concluded that although the interciliary zomdes are under stress in vivo the elastic behavior of the ciliary body could not be entirely attributed to these zomdes. It is suggested that, since pressure in the suprachoroidal space is lower than intraocular pressure due to the elasticity of ciliary body and choroid, in the presence of ocular hypotony the suprachoroidal pressure may fall below atmospheric pressure, encouraging transudation into the space. The distribution of the transudate is explained by the distribution of the suprachoroidal lamellae
