Scientific notes
Libelle of note
The Tunica fibrosa has been subdivided into the Sclera, the Cornea and the Limbus corneae, a transitional zone between sclera and cornea, of utmost importance for the maintenance of intra-ocular pressure, since the removal of aqueous humor occurs here. The terminology used follows Hogan MJ, Alvarado JA, Weddell JE (1971) Histology of the Human Eye. Saunders, Philadelphia, PA.
New term; the Venulae aquosae ('Wasservenen') were described by Ascher KW (1942) Am J Ophthalmol 25:31. They collect the Humor aquosus from the Sinus venosus sclerae, and drain into the Venae episclerales.
