Summary
-
1.
The influence of intravenously and topically applied catechol-amines on intraocular pressure (IOP) in normal and decentralized eyes was studied in the rabbit.
-
2.
After topical application, adrenaline induced a decrease in IOP. The response was much more pronounced in decentralized eyes, indicating the development of decentralization supersensitivity.
-
3.
The intravenous infusion of noradrenaline (10−5 g·kg−1 · min−1 for 5 min) increased both arterial blood pressure and IOP. The hypertensive response was approximately the same in normal and decentralized eyes. The increase in IOP is probably due to the rise in blood pressure. In this context, there were no signs of supersensitivity after decentralization, indicating that the increase in IOP is not brought about by a direct influence of the drug on the eye itself.
-
4.
The present results once more confirm the opinion that abrupt changes in arterial or venous blood pressure are followed by similar change in IOP.
