Über Lufteinblasung unter die Bindehaut, in das Hornhautparenchym und in die Vorderkammer

Summary

Experimental insufflation of air into different parts of the eye of rabbits has proved:

• 1. It is possible to press air into the bulbar part of the conjunctiva. Only very small bubbles penetrate, if ever, a part of the conjunctiva proximate to the limbus, no air at all into the tarsal conjunctiva. The position of blood vessels can be easily seen with the slit-lamp when the conjunctiva is insufflated.

• 2. It is possible to produce, by air insufflation into the cornea, interlamellar tubular spaces, which, when very numerous and tightly packed, give to the cornea a snow-white foamy aspect. The parts of the parenchyma next to the Descemet membrane are not insufflated, wich indicates a denser layer of these corneal lamellae.

  It is also possible to divide, by air insufflation, the corneal parenchyma in two layers and to transform the cornea into a monolocular cyst.

• 3. The air insufflation of the anterior chamber shows the location and deformation of air bubbles. These are always divided and separated from the wall of the anterior chamber by a thin layer of liquid. Microbubbles on the surface of major bubbles are visible. The iridocorneal angle can be directly seen when the anterior chamber is filled with air.

  The appendix shows a diagram which represents the volume and the surface of a schematic anterior chamber by variation of its depth (h). R = 6,8 mm, Ø = 11 mm, h = 0–4 mm.
