<prompt> Acetazolamide decreases intraocular pressure by what mechanism: September 2010Decreases aqueous humor productionDecreases vitreous volumeIncreased drainage of aqueousNone of the above  <response>: Ans. A: Decreases aqueous humor production Acetazolamide is a carbonic anhydrase inhibitor, which means that it forces the kidneys to excrete bicarbonate HCO;, thus re-acidifying the blood. It also lowers intraocular tension by decreased formation of aqueous humour It is rich in bicarbonate
