Which statement about the efficacy of prostaglandin analogs is true?

Explanation:
Prostaglandin analogs lower intraocular pressure by increasing the outflow of aqueous humor, mainly through the uveoscleral pathway. This effect is strong and reliable, with an average IOP reduction in the roughly 25–35% range, commonly summarized as about 30%. That makes the statement describing around a 30% drop the most accurate reflection of their efficacy. They’re typically used once daily and are generally well tolerated, though side effects like conjunctival redness, eyelash growth, and iris darkening can occur; these do not negate the IOP-lowering effect. The other possibilities are not consistent with how these drugs work or their impact on IOP.
