Ved at hæmme karboanhydrase i øjets ciliære processer nedsættes kammervand sekretionen, formodentlig ved at sinke dannelsen af bikarbonationer medførende reduktion i natrium og væske transport.
Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humour secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fluid transport.
