Glucocorticoids are potent anti-inflammatories, regardless of the inflammation's cause; their primary anti-inflammatory mechanism is lipocortin-1 (annexin-1) synthesis. Lipocortin-1 both suppresses phospholipase A2 , thereby blocking eicosanoid production, and inhibits various leukocyte inflammatory events ( epithelial adhesion , emigration , chemotaxis , phagocytosis , respiratory burst , etc.). In other words, glucocorticoids not only suppress immune response, but also inhibit the two main products of inflammation, prostaglandins and leukotrienes . They inhibit prostaglandin synthesis at the level of phospholipase A2 as well as at the level of cyclooxygenase /PGE isomerase (COX-1 and COX-2), [29] the latter effect being much like that of NSAIDs , potentiating the anti-inflammatory effect.

* Mydriatics and cycloplegics. While certainly not a systemic medication, it is worth noting that topical tropicamide may cause increased IOP via mechanisms other than angle closure. After examining IOP fluctuations in children given mydriatics, researchers found an average increase of 2mm Hg; however, a potential increase or decrease of 8mm Hg was documented in many patients with open angles. 27 The investigators concluded that some alteration in aqueous dynamics occurred upon dilation and, because of the variable effect on IOP (even without the presence of anterior segment complications), all patients who use mydriatics require observation. 27
