Influence of estrogens on intraocular tension in the eyeballs of rabbits.

Iridocorneal angles from the eyes of female rabbits subjected to large doses of estrogens were examined under an electron scanning microscope. A temporary rise in intraocular tension was noted lasting up to 24 h after injection of estrogens, followed by a slow return to normal conditions. Histostructural changes of the iridicorneal angle were observed as widening of the marginal sector, enlarging of the dimple-shaped depressions and also increased number and narrowing of the micropores in the central part of the iridocorneal field.

Scanning microscope observations of alcali-burned rabbit cornea treated with embryonic corneal homogenisates.

The process of epithelial regeneration of alcali-burned rabbit cornea was observed in control animals and in animals treated with bovine embryonic corneal homogenates using scanning electron microscopy. It was found that regeneration is more rapid when homogenate treatment is applied, but follows the same stages as observed in the control animals.
