Ring-shaped acid burns of the rabbit cornea.
In the extension of our previous work on alkali burns of the rabbit cornea we have studied acid burns of the rabbit cornea using a ring-shaped chromoatographic paper soaked with solutions of different kinds of acids. The ensuing changes were studied with the silver methods of McGovern and Jabonero.
Ring-shaped alkali burns of the rabbit cornea. III. Late phase of the stroma reaction.
The present paper deals with late changes of the corneal stroma after alkali burns from the 5th day after the injury up to the 58th day. As has been pointed out in a previous paper, between the 3rd and 5th day the process of healing within the corneal stroma changes and at the end a dense scar ensues.
Glaucomatous cupping of the human optic disk: a neuro-histologic study.
The optic nerve and optic disk in 20 cases of glaucoma were examined neurohistologically. The interruption of retinal axons was found localized in a narrow transversal strip at the level of the posterior part of the lamina cribrosa and immediately behind it. Retinal axons anterior to this zone were mostly intact as long as their ganglion cells of origin were preserved. This picture was essentially identical in cases of primary and secondary glaucoma. The significance of this finding is discussed together with some hypotheses on the origin and causes of the glaucomatous cupping of the optic disk.
Ring-shaped alkali burns of the rabbit cornea. II. Early changes of the corneal stroma.
Corneas of 32 rabbits were coagulated in a circular zone of 1 mm width and 10 mm diameter. The results of the experiment showed sharply limited injury throughout the entire depth of the cornea without lateral diffusion. The reactions of the corneal stroma during the first three days are described and discussed.

Ring-shaped alkali burns of the rabbit cornea. Epithelial and endothelial changes.
Rabbit corneas were burned by touching their surfaces with rings of Whatman No. 1 chromatographic paper soaked in 1N NaOH. The corneal epithelium and endothelium were studied by impregnating flat sections with McGovern's and Jabonero's silver stains. Immediate destruction as well as regeneration of both cellular layers is described.
Activated human retinal microglia under pathological conditions.
Six pathological human retinas were studied in order to establish changes, migration, and other reactions of retinal microglia. The different morphological features of other retinal macrophages are also described. Hortega silver carbonate stain was used for this study. This investigation aided in answering some questions on the active movements of microglia elements and other details under discussion.
