Which class is known to lower episcleral venous pressure as part of its action?

Explanation:
Rho-kinase inhibitors lower episcleral venous pressure as part of how they help reduce IOP. They work by relaxing the smooth muscle in the trabecular meshwork to boost conventional outflow, and they can also relax vascular smooth muscle in the episcleral veins. This venous relaxation lowers EVP, which reduces the pressure opposing aqueous drainage and contributes to a further drop in IOP. Other classes mainly lower IOP by reducing aqueous production or by increasing outflow through alternative (uveoscleral) routes, without the EVP-lowering effect. So the class known to decrease EVP as part of its action is the Rho-kinase inhibitors.
