Prostaglandin analogs (PGAs) lower intraocular pressure by approximately what percent?

Explanation:
Prostaglandin analogs lower intraocular pressure primarily by increasing uveoscleral outflow, leading to a typical reduction that centers around 30% on average. In many patients, the IOP drops about a quarter to a third, with 30% representing the common mean response. Individual results vary, but this value mirrors the usual expected effect for standard dosing. Reductions near 10% are smaller than expected for a PGA, while reductions around 50% or more are not typical with standard therapy, making the 30% figure the best representative choice.
