Study: Glaucoma meds and dry eye (again)

Another one in a very tall and growing stack.

What will it take to turn the tide?

We have a few preservative-free meds now, but insurers won’t cover them and who can afford them?

Tear Film, Conjunctival and Corneal Modifications Induced by Glaucoma Treatment. Roberti et al, Curr Med Chem. 2019 May 17

Abstract

Ocular surface disease is characterized by tear film instability and histopathologic and clinical changes of the ocular surface. Glaucoma patients often suffer from ocular surface disease caused by the chronic use of preserved medical treatment to reduce intraocular pressure. Benzalkonium chloride is the preservative most frequently used in glaucoma medications. Its effect on tear film, conjunctiva and cornea and the consequences in glaucoma management are discussed in this mini-review.
