Ludwig Laqueur
Ludwig Laqueur (July 25, 1839 – April 20, 1909) was a German ophthalmologist born in Twardogóra, Festenberg, Silesia. He was the father of historian Richard Laqueur (1881–1959). He studied medicine in Breslau and Berlin, earning his doctorate in 1860. From 1863 to 1869 he worked as an assistant at Richard Liebreich's ophthalmological hospital in Paris. In 1872 he became an associate professor at the University of Strasbourg, where in 1877 he was appointed a full professor of ophthalmology. Among his assistants at Strasbourg was Paul Silex (1858-1929). Laqueur is remembered for his research of physostigmine, a chemical substance found in the Calabar bean (''Physostigma venenosa'') of West Africa. In 1876 he published ''Ueber eine neue therapeutische Verwendung des Physostigmin'', suggesting the use of physostigmine for the treatment of glaucoma . Laqueur noticed that extracts of the Calabar bean significantly lowered intraocular pressure. He could attest to these results firs ...

Glaucoma
Glaucoma is a group of eye diseases that result in damage to the optic nerve (or retina) and cause vision loss. The most common type is open-angle (wide angle, chronic simple) glaucoma, in which the drainage angle for fluid within the eye remains open, with less common types including closed-angle (narrow angle, acute congestive) glaucoma and normal-tension glaucoma. Open-angle glaucoma develops slowly over time and there is no pain. Peripheral vision may begin to decrease, followed by central vision, resulting in blindness if not treated. Closed-angle glaucoma can present gradually or suddenly. The sudden presentation may involve severe eye pain, blurred vision, mid-dilated pupil, redness of the eye, and nausea. Vision loss from glaucoma, once it has occurred, is permanent. Eyes affected by glaucoma are referred to as being glaucomatous. Risk factors for glaucoma include increasing age, high pressure in the eye, a family history of glaucoma, and use of steroid medication. F ...

Academic Staff Of The University Of Strasbourg
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. 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 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, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rudolf Virchow
Rudolf Ludwig Carl Virchow (; or ; 13 October 18215 September 1902) was a German physician, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician. He is known as "the father of modern pathology" and as the founder of social medicine, and to his colleagues, the "Pope of medicine". Virchow studied medicine at the Friedrich Wilhelm University under Johannes Peter Müller. While working at the Charité hospital, his investigation of the 1847–1848 typhus epidemic in Upper Silesia laid the foundation for public health in Germany, and paved his political and social careers. From it, he coined a well known aphorism: "Medicine is a social science, and politics is nothing else but medicine on a large scale". His participation in the Revolution of 1848 led to his expulsion from Charité the next year. He then published a newspaper ''Die Medizinische Reform'' (''The Medical Reform''). He took the first Chair of Pathological Anatomy at the University of Wü ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Von Graefe (ophthalmologist)
Friedrich Wilhelm Ernst Albrecht von Gräfe, often Anglicized to Graefe (22 May 182820 July 1870), was a Prussian pioneer of German ophthalmology. Graefe was born in Finkenheerd, Brandenburg, the son of Karl Ferdinand von Graefe (1787–1840). He was the father of the far right politician Albrecht von Graefe (1868–1933). Background At the University of Berlin, Graefe studied philosophy, logic, natural sciences and anatomy, under notable names such as Dove, H. Rose, Müller, and Schlemm, eventually obtaining his medical doctorate in 1847. He continued his studies at Prague, Paris, Vienna and London, and having devoted special attention to ophthalmology, in 1850, he began to practice as an oculist in Berlin. Here, he founded a private institution for the treatment of eyes. During the same year, he received his habilitation with the thesis ''Über die Wirkung der Augenmuskeln''. In 1858 he became an associate professor of ophthalmology at the Charité in Berlin, where in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Margherita Ligure
Santa Margherita Ligure ( lij, Santa Margaita) is a ''comune'' (municipality) in the Metropolitan City of Genoa in the Italian region Liguria, located about southeast of Genoa, in the area traditionally known as Tigullio. It has a port, used for both tourism and fishing activities. Part of ''comune '' territory is included in the Regional Natural Park of Portofino. Santa Margherita Ligure borders the following municipalities: Camogli, Portofino, Rapallo. History The presence of a Roman settlement has not been definitely proven. The burgh, known as ''Pescino'', was devastated by Rothari in 641 and by the Saracens in the 10th century. Later it was a fief of the Fieschi family until 1229, when it was acquired by the Republic of Genoa. In 1432 it was attacked by the fleet of Venice and in 1549, together with Rapallo, by that of Turgut. In 1813, under the Napoleonic domination, the two burghs of ''Pescino'' and ''Corte'' were unified as ''Porto Napoleone''. Two years later it was ann ...

Intraocular Pressure
Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury ( mmHg). Physiology Intraocular pressure is determined by the production and drainage of aqueous humour by the ciliary body and its drainage via the trabecular meshwork and uveoscleral outflow. The reason for this is because the vitreous humour in the posterior segment has a relatively fixed volume and thus does not affect intraocular pressure regulation. An important quantitative relationship (Goldmann's equation) is as follows: :P_o = \frac + P_v Where: * P_o is the IOP in millimeters of mercury (mmHg) * F the rate of aqueous humour formation in microliters per minute (μL/min) * U the resorption of aqueous humour through the uveoscleral route (μL/min) * C is the facility of outflow in micr ...

Calabar Bean
''Physostigma venenosum'', the Calabar bean or ordeal bean, is a leguminous plant, Endemic to tropical Africa, with a seed poisonous to humans. It derives the first part of its scientific name from a curious beak-like appendage at the end of the stigma, in the centre of the flower; this appendage, though solid, was supposed to be hollow (hence the name from , a bladder, and stigma). Growth The plant is a large, herbaceous, climbing perennial, with the stem woody at the base, up to in diameter; it has a habit like the scarlet runner, and attains a height of about . The flowers, appearing in axillary peduncles, are large, about long, grouped in pendulous, fascicled racemes pale-pink or purplish, and heavily veined. The seed pods, which contain two or three seeds or beans, are in length; and the beans are about the size of an ordinary horse bean but less flattened, with a deep chocolate-brown color.
