The present review casts a critical eye on intraocular pressure (IOP) monitoring and its value in current and future glaucoma care. Crucially, IOP is not fixed, but varies considerably during the 24-h cycle and between one visit and another. Consequently, a single IOP measurement during so-called office hours is insufficient to characterize the rea...

Carbonic anhydrase inhibitors are IOP-lowering sulfonamide derivatives which inhibit the activity of CA in the ciliary processes of the eye, thus reducing aqueous humor formation and consequently decreasing IOP. Systemic CAIs provide an approximately 40% IOP reduction, and their effect develops rapidly. Therefore, systemic CAIs (most frequently ace...
