[Studies on oxygen content of aqueous humor in the anterior chamber of rabbit's eye--II. Oxygen content of aqueous humor in anterior chamber and arterial blood in experimentally provoked ischemia].

The ligature of the right common carotid artery has been performed in 20 rabbits. Then, the partial pressure of oxygen pO2 in the aqueous humor of anterior chamber of the both eyes and in the right and left ear artery was measured. An electrochemical polarographic oxymeter was used for this purpose. The measurements were carried out on the second day, in a week and in one month after performing the ligature. A statistically significant decrease of pO2 in aqueous humor of anterior chamber of the right eye and of ear artery on the right side was observed, especially on the second day and after a week. Blood circulation stoppage within the right common carotid artery causes, in spite of the preservation of collateral circulation, a significant pO2 decrease in aqueous humor. The pO2 measurement would be a valuable supplement to the methods applied in the measurement of ear artery blood circulation.
