At Hill Vision Services, we are proud to offer two, new, groundbreaking glaucoma eye drops representing entirely new classes of glaucoma medications. Vyzulta (latanoprostene bunod ophthalmic solution 0.024%) and Rhopressa (netarsudil ophthalmic solution 0.02%) are both promising glaucoma therapies that lower eye pressure by targeting the diseased tissue in glaucoma patients — the trabecular meshwork.

To understand these new medications, let’s first describe how the gold standard of glaucoma medications, prostaglandins, accomplishes reduction of intraocular pressure (pressure inside the eye).

If we think of eye pressure and its control as a plumbing system, there is a “faucet” that produces fluid (the aqueous humor) and a drain (actually two drainage systems-the primary, trabecular meshwork and the secondary, uveoscleral outflow path). While some medications “turn off the faucet,” others reduce intraocular pressure by increasing flow through the drain. Prostaglandins work primarily by increasing flow through the secondary, uveoscleral path.

While all of these types of medications will result in lowered eye pressure, none of the “older” glaucoma medications targeted the trabecular meshwork, the primary pathway for aqueous humor drainage. Both new medications make this drainage more effective, but they do it slightly differently.

What are Vyzulta Glaucoma Eye Drops?

Vyzulta is somewhat of an “updated” prostaglandin analogue with its addition of a nitric oxide component. Nitric oxide helps to dilate blood vessels in the eye which, in turn, increase oxygen supply to the optic nerve as well “relax” the trabecular meshwork, improving drainage of the aqueous humor.

Vyzulta is appro­priate as either a first-line treatment option for patients with glaucoma or ocular hypertension, or it can be used along with other medications. It is prescribed once daily and has few side effects.

Vyzulta might be good for patients who have done well on prostaglandin, but maybe it has lost a bit of its effectiveness. Vyzulta may lower eye pressure in order to get back into a safer range.

What are Rhopressa Glaucoma Eye Drops?

Like Vyzulta, Rhopressa is a once-daily eye drop; it is, however, a different class of drug than we’ve ever had before. Rhopressa is known as a kinase inhibitor, also known as ROCK inhibitor, and it helps to lower eye pressure by relaxing the trabecular meshwork and the canal that drains the aqueous humor from the front chamber of the eye. This decreases the resistance of drainage in the conventional outflow pathway, thus lowering eye pressure.

Rhopressa might be a good alternative for patients who have tried a prostaglandin and found out that they have an allergy or sensitivity to the medication. Rhopressa also combines well with other types of glaucoma drops.

Is Vyzulta or Rhopressa Covered by Insurance?

Until recently, Rhopressa and Vyzulta glaucoma eye drops had been used only when regular eye drops were tried without success, and many insurance carriers did not cover it. Over time, however, insurance coverage has increased. Please check with your insurance provider.
