Josef Flammer

Josef Flammer looked at glaucoma, a leading cause of blindness, and saw a puzzle where others saw a simple equation. For decades, the condition was defined by high intraocular pressure. As the long-time director of the University Eye Clinic in Basel, Flammer's meticulous research challenged this orthodoxy. He proposed and proved a radical new pathogenetic concept: that a fragile, unstable blood supply to the optic nerve, leading to localized oxidative stress, was a primary culprit in the death of retinal cells. This wasn't just an academic theory; it fundamentally changed how glaucoma is understood and managed. It explained why patients with normal pressure could still lose their sight and opened the door to neuroprotective treatments aimed at improving blood flow and combating oxidative damage. Flammer's work shifted the medical gaze from a single number on a pressure test to a holistic view of the eye's vascular health, giving doctors new tools and hope for preserving vision.
