Rocklatan lowers IOP by how many mmHg more than PGA alone?

Explanation:
The key idea is that combining a prostaglandin analogue with a ROCK inhibitor can yield an extra drop in IOP beyond what the prostaglandin alone achieves. In studies, Rocklatan produced about 2 mmHg more IOP lowering than latanoprost alone on average. This reflects how the two drugs work together: latanoprost mainly increases uveoscleral outflow, while netarsudil (the ROCK inhibitor) improves outflow through the trabecular meshwork and can also lower episcleral venous pressure. The result is a modest but consistent additional reduction, which is why the correct choice is the 2 mmHg extra. The other options don’t match the observed incremental effect in the trials.
