The mechanism of action is thought to be ability to block prostaglandin synthesis by inhibiting cyclooxygenase 1 and 2. In studies performed in animal eyes, prostaglandins have been shown to produce disruption of the blood–aqueous humor barrier, vasodilation, increased vascular permeability, leukocytosis, and increased intraocular pressure
