Studies on the Cornea
Physiological studies have demonstrated that ions, as well as large molecules such as hemoglobin or fluorescein, can diffuse across and within the cornea. Most of the substrates for corneal metabolism are obtained from aqueous humor filling the anterior chamber. In order to receive its nutrients and in order to maintain its normal conditions of hydration, the avascular cornea must transport rel...
متن کاملImmunohistologic Studies on Antigen-antibody Reactions in the Avascular Cornea
The injection of antigen into the center of the avascular cornea of homologously sensitized animals induced a ring of opacification between the center of the cornea and the limbus. This ring of opacification was composed of a line of deeply eosinophilic amorphous material in a matrix of swollen collagen fibers, palisaded by polymorphonuclear leucocytes. By use of fluor-tagged antigen, it was sh...
متن کاملPolarized Light Studies of the Cornea
A. THE MEASUREMENT OF THE RETARDATION OF THE CORNEA Preliminary experiments on the change of corneal retardation with changes in intra-ocular pressure have been described elsewhere (Stanworth, 1949, 1950). Theoretical considerations, together with measurements of the retardation of the cornea at different pressures with transmitted light passing in various directions, led to the conclusion that...
متن کاملSTUDIES ON THE CORNEA III. The Fine Structure of the Frog Cornea and the Uptake and Transport of Colloidal Particles by the Cornea in vivo
The fine s tructure of the frog cornea has been studied and compared wi th tha t of the r a b b i t cornea (1, 2) par t icular ly in re la t ion to the uptake and t ranspor t of colloidal particles. The frog corneal endothe l ium does not possess a terminal bar and the fluid space of the intercellular space is apparent ly cont inuous with tha t of the anter ior chamber . Colloidal markers (ThO2...
