Mati Therapeutics is also developing a punctal plug delivery system for latanoprost and other agents, Dr. Cantor said. However, the bigger concern will be whether Medicare or third-party payers will cover the cost involved with newer drug delivery devices, Dr. Trubnik said. When it comes to implantable drug delivery systems, such as iDose, one concern would be whether it is worthwhile to have patients take multiple trips to the OR to implant devices that deliver medications, considering a possible increased infection risk— and how to handle patients who don’t return for follow up if the technology is not biodegradable. Another consideration among the technology options is a continuous pressure monitoring device that would provide 24- hour IOP monitoring. “Their widespread use has not been adopted, although this is an area of interest in the glaucoma community,” Dr. Angelilli said. There are also newer therapies for glaucoma patients to consider, such as the Rho-kinase inhibitor netarsudil (Rhopressa, Aerie *…>À“>ViṎV>Ã® >˜` ̅i wÝi` combination of netarsudil and latanoprost (Roclatan, Aerie Pharmaceuticals), which was I t is undeniable that surgical and medical glaucoma management have been revolutionized over the past decade.

A single iStent may not be as good as two or three as in many reports; therefore, their cost is yet an issue in many countries. Subconjunctival MIGS such as XEN or InnFocus have easily aroused the interest of many more surgeons, particularly in Asia, since the subconjunctival area is vast and easily manipulated. It may be in part due to Asian eyes having rather stronger tissue response to surgery than Caucasian eyes and glaucoma presentation tends to be rather more advanced. Connecting anterior chamber and subconjunctival space with a microstent which is simply visible postoperatively may more quickly achieve successful IOP lowering, if needed. ," ˆ˜…ˆLˆÌœÀ ̅>Ì “œ`Տ>Ìià ÌÀ>LiVՏ>À “iÅܜÀŽ œÕÌyœÜ…>à Vœ“i ˆ˜Ìœ ̅i “i`ˆV> ÌÀi>̓i˜Ì ëœÌˆ}…Ì° iÈ`ià "* œÜiÀˆ˜} ivwV>VÞ 3 ] Ài«œÀÌà œv ˆ˜VÀi>Ș} Àï˜> Lœœ` yœÜ] «ÀœÌiV̈˜} ˜iÕÀœ˜Ã >}>ˆ˜ÃÌ stress, promoting wound healing as well as treatment of Fuchs’ endothelial dystrophy 4,5 are their potential Li˜iwÌ𠜘Õ˜V̈Û>…Þ«iÀi“ˆ>] ̅i “œÃÌ Vœ˜ViÀ˜ˆ˜} >`ÛiÀÃi iÛi˜Ì] Ü>à V>ˆ“i` ÌÀ>˜Ãˆi˜Ì >˜` “ˆ` 6 .

Punctal plugs and injectable implants that deliver medication to patients could help with the dilemma of patient compliance, Dr. Trubnik said. “We already have plugs on the market with steroids but not for glaucoma drugs,” she said.
