Novel neurostimulator device uses nasal cavities to stimulate tearsChronic dry eye disease (DED) affects more than 25 million people and to date the only pharmacologic therapies are topical or involve punctal plugs. Results from two studies wth a neurostimulator indicate there may be a new pathway to upregulate the body’s tear system.
Exploring risk, reward in trabecular bypass, suprachoroidal devices
Exploring risk, reward in trabecular bypass, suprachoroidal devicesThough much focus for stents has been in the trabecular meshwork, many companies are currently developing suprachorodial devices, which are in various stages of FDA review.
Device makers swing for fence with new technologiesDevice manufacturers presenting new implants and technologies to treat glaucoma. As the industry moves from 1.0 devices to 2.0 devices, this will be a transformative time in the way physicians treat patients.
What astronauts can teach us about glaucoma
What astronauts can teach us about glaucomaNASA’s Vision Impairment and Intracranial Pressure (VIIP) project was started after NASA realized many astronauts return from space with vision problems, and these problems may last for years after mission completion.
Intracanalicular drug depot may fill unmet need for better topical therapyA sustained-release dexamethasone intracanalicular depot may be able to treat post-cataract surgery inflammation without causing spikes in IOP. The product’s one-time administration may also improve compliance and convenience.
Regulating IOP in space—and redefining glaucomaJohn Berdahl, MD, is the developer of Balance Goggles, eyewear intended to help regulate the pressure inside the eye.
