Arthur Groenouw
Arthur Groenouw (27 March 1862 – 1945) was a German ophthalmologist born in Bosatz, a village near Ratibor. He studied medicine in Breslau, and was an assistant to physiologist Rudolf Heidenhain (1834–1897) and ophthalmologist Wilhelm Uhthoff (1853–1927). In 1892 he was habilitated for ophthalmology in Breslau, and in 1899 attained the title of professor. In 1890 Groenouw described two different types of corneal dystrophy, of which he wrote about in an article titled "''Knötchenförmige Hornhauttrübungen''" (noduli corneae). At the time, he believed that the two types were variations of the same disease. Later on, his findings on corneal dystrophy were classified as two separate syndromes: * " Groenouw Type I": Granular type of corneal dystrophy. Characterized by discrete grey opacities scattered over the surface of the cornea. * " Groenouw Type II": Macular type of corneal dystrophy. Characterized by greyish white opaque granules with sharp borders, mostly in cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ophthalmologist
Ophthalmology (, ) is the branch of medicine that deals with the diagnosis, treatment, and surgery of eye diseases and disorders. An ophthalmologist is a physician who undergoes subspecialty training in medical and surgical eye care. Following a medical degree, a doctor specialising in ophthalmology must pursue additional postgraduate residency training specific to that field. In the United States, following graduation from medical school, one must complete a four-year residency in ophthalmology to become an ophthalmologist. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology. Ophthalmologists prescribe medications to treat ailments, such as eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists provide both primary and specialty eye care—medical and surgical. Most ophthalmologists participate in academic research on eye diseases at some point in their training and many incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornea
The cornea is the transparency (optics), transparent front part of the eyeball which covers the Iris (anatomy), iris, pupil, and Anterior chamber of eyeball, anterior chamber. Along with the anterior chamber and Lens (anatomy), lens, the cornea Refraction, refracts light, accounting for approximately two-thirds of the eye's total optical power. In humans, the refractive power of the cornea is approximately 43 dioptres. The cornea can be reshaped by surgical procedures such as LASIK. While the cornea contributes most of the eye's focusing power, its Focus (optics), focus is fixed. Accommodation (eye), Accommodation (the refocusing of light to better view near objects) is accomplished by changing the geometry of the lens. Medical terms related to the cornea often start with the prefix "''wikt:kerat-, kerat-''" from the Ancient Greek, Greek word κέρας, ''horn''. Structure The cornea has myelinated, unmyelinated nerve endings sensitive to touch, temperature and chemicals; a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Breslau Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Mi ...

Academic Staff Of The University Of Breslau
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

Macular Corneal Dystrophy
Macular corneal dystrophy, also known as Fehr corneal dystrophy, is a rare pathological condition affecting the stroma of cornea first described by Arthur Groenouw in 1890.Groenouw A. Knötchenförmige Hornhauttrübungen (noduli corneae). Arch Augenheilkunde. 1890;21:281–289. Signs are usually noticed in the first decade of life and progress afterwards, with opacities developing in the cornea and attacks of pain. This gradual opacification leads to visual impairment often requiring keratoplasty in the later decades of life. Epidemiology While Macular Corneal Dystrophy is found throughout the world, countries with the highest prevalence include Iceland, Saudi Arabia, India, and the United States. In Iceland, MCD accounts for almost one-third of all corneal grafts performed. Estimates from Claims Data in the United States place the prevalence of MCD at 9.7 per million, which represents less than 1% of corneal dystrophies. Pathophysiology Macular Corneal Dystrophy is an autoso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Granula
Granula was the first manufactured breakfast cereal. It was invented by James Caleb Jackson in 1863. Jackson and many of his contemporaries believed that the digestive system was the basis of illness. He therefore began experimenting at his upstate New York health spa with cold cereal as an illness cure; the development of Granula was the outcome of his experiments. Granula could be described as being a larger and tougher version of the somewhat similar later cereal Grape-Nuts. However, it consisted primarily of bran-rich graham flour made into nugget shapes. The cereal had to be soaked overnight before it could be eaten. The cereal was manufactured from a dough of graham flour rolled into sheets and baked. The dried sheets were then broken into pieces, baked again, and broken into smaller pieces. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granular Corneal Dystrophy Type I
Granular corneal dystrophy is a slowly progressive corneal dystrophy that most often begins in early childhood. Granular corneal dystrophy has two types: * Granular corneal dystrophy type I, also corneal dystrophy Groenouw type I, is a rare form of human corneal dystrophy. It was first described by German ophthalmologist Arthur Groenouw in 1890. * Granular corneal dystrophy type II, also called Avellino corneal dystrophy or combined granular-lattice corneal dystrophy is also a rare form of corneal dystrophy. The disorder was first described by Folberg et al. in 1988. The name Avellino corneal dystrophy comes from the first four patients in the original study each tracing their family origin to the Italian province of Avellino. Presentation Granular corneal dystrophy is diagnosed during an eye examination by an ophthalmologist or optometrist. The lesions consist of central, fine, whitish granular lesions in the cornea. Visual acuity is slightly reduced. Genetics Granular co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
