Abstract

After the intraocular bleeding was inuced by amputation of the rabbit retinal artery, the level and duration of the level of the intraocular pressure to control the bleeding was studied. Then, the eyes were enucleated and evaluated for the effect of the increased intraocular pressure. In 3 of 4 eyes studied, the bleeding is controlled at the height of 140-145 cm of the infusion bottle for 10 seconds. And the maintenance of the height of 125 cm for 15 seconds was effective in one eye. Although the expanded intercellular space in the outer nuclear layer, destruction of the photoreceptors and formation of the vacuoles appeared in the first week, they were only the temporary findings for they disappeared after second week. In the rebbit, the retinal arterial bleeding is able to be controlled at the level of about 100 mmHg of the IOP for about 10 seconds effectively and safely.
