Abstract
• The topical application of prostaglandin E2 (dinoprostone) is followed by massiveswelling of the ciliary process, leading to substantial leakage of marker dye into the posterior chamber and directly into the region of the iris, where the primary ciliary processes insert. In contrast, blood vessels of the iris proper retain most of their normal barrier quality and do not leak Evans blue dye.
The adrenergic innervation of the anterior segment remains normal in density and in quality after the topical application of PGE2.
