Josef Flammer (born April 21, 1948) is a Swiss ophthalmologist and long-time director of the Eye Clinic at Basel University Hospital. Flammer is a glaucoma specialist who developed a new pathogenetic concept of glaucomatous damage according to which unstable blood supply leads to oxidative stress, which in turn plays a major role in apoptosis (cell death) of cells in the optic nerve and retina in glaucoma patients.[1]

Flammer's scientific and medical endeavors were generally interdisciplinary. His first research focus was automatic perimetry for which he established normal values;[2] he studied short term and long term fluctuations of the human visual field and described influencing factors.[3] Together with Hans Bebie he developed the so-called Bebie curve, which plays a major role in the diagnosis of visual field loss due to glaucoma, he introduced the visual field indices. Flammer was one of the first researchers to demonstrate systemic side effects of locally administered beta blockers (i.e. eye drops) in ophthalmology. Flammer and his collaborators found that intraocular pressure variation is as important for the development of glaucoma, one of the main causes of blindness worldwide, as a constantly elevated intraocular pressure,[4] long considered the main, if not the only, cause of glaucoma. In numerous research projects he demonstrated that glaucoma could be caused by a dysregulation of ocular blood flow, even at normal levels of intraocular pressure. Flammer discovered that vasospasms in the eye are a manifestation of a general vasospastic syndrome. Later, he noted that such spasms are only the tip of the iceberg and an indication of a much more generalized vascular dysregulation in the human body.[5][6] This increases the risk of eye disease, in particular of normal tension glaucoma.[7] Flammer noted that people with a primary vascular dysregulation have other symptoms and signs; this led to the establishment of the term Flammer syndrome. Flammer also demonstrated the relationship between eye disease and heart disease.[8][9] In numerous laboratory studies, he contributed to the understanding of the role of endothelin - which according to his studies regulates retinal venous pressure - and nitric oxide in ocular perfusion.[10] He also described the pathogenic role of ocular blood flow in retinitis pigmentosa.[11]
In addition to hundreds of original papers, Flammer is the author of several books. His book "Glaucoma", intended for the general public, has so far been published in 22 languages and went through 30 different editions; "Glaucoma" is thus considered the world's most widely used non-fiction book on this ocular disease.[12] His "Basic Sciences in Ophthalmology" has received praise for demonstrating the role of chemistry and physics in modern ophthalmological diagnostics and therapies.[13] The Basel Eye Clinic organizes each year - as initiated by Flammer - one of the most renowned conferences for ophthalmologists in Europe, the Basel Ophthalmo Meeting.[14]
