Oral CAIs can lower IOP by what percent?

Explanation:
Systemic carbonic anhydrase inhibitors lower IOP mainly by reducing aqueous humor production in the ciliary body. Because their effect depends on dose, timing, and individual response, the typical decrease in IOP with oral CAIs spans a broad but moderate range. In practice, the expected reduction is about 10% to 50%, with many patients experiencing roughly a 20–40% drop. Reductions as small as 5–15% are not the usual expectation for this drug class, while very large drops (50–90%) are uncommon outside specific circumstances. This makes the 10–50% range the most accurate general statement.
