Acetazolamide decreases intraocular pressure by what mechanism: September 2010
Decreases aqueous humor production
Decreases vitreous volume
Increased drainage of aqueous
None of the above
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)
