Erich Seidel (ophthalmologist)
Erich Seidel (1882–1946) was a German ophthalmologist known for his studies in the field of glaucoma, ocular anesthesia and aqueous humor dynamics. Seidel test and Seidel's scotoma are named after him. Biography Erich Seidel was born on 1882 December 30 at Apolda, Thüringen, Germany. He received MD from Jena in 1907 (Topic: über die Lidbildung mittels übertragener stiellser Hautlappen (eyelid formation by means of transferred skin flaps)). After specialising in Ophthalmology during 1907-1910, he began working as an assistant at the University of Heidelberg Eye Clinic in 1910 and was appointed Head Physician in 1916 and Ausserordentlicher Professor in 1919. In 1935 he was offered to join at the University of Gottingen, but he rejected. Receiving habitation in Heidelberg in 1914, his inaugural address was on the problems of spectacle glasses and solutions through modern spectacle optics. He spent his last days in Jene, East Germany. He died on February 26, 1946. Scientif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apolda
Apolda () is a town in central Thuringia, Germany, the capital of the Weimarer Land district. It is situated in the center of the triangle Weimar–Jena–Naumburg near the river Ilm, c. east by north from Weimar. Apolda station lies on the Halle–Bebra railway, which is part of the main line from Berlin to Frankfurt. History Apolda was first mentioned in 1119. Until 1633 it was seat of a family of nobles, the Vitzthums, which acted relatively independent. Between 1633 and World War I Apolda was property of the University of Jena. Nevertheless, from 1691 to 1809 Apolda was part of the Duchy of Saxe-Weimar and from 1809 to 1918 of Saxe-Weimar-Eisenach (after 1815 Grand Duchy). Around 1700, the knitting industry began to grow, so that finally, at the end of the 19th century, Apolda was the wealthiest town of the whole region. On July 12–17, 1945, Apolda issued a set of three of its own postage stamps. They depicted a new sprig growing up out of a tree stump. After World War II, ...

People From Apolda
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Anterior Chamber
The anterior chamber ( AC) is the aqueous humor-filled space inside the eye between the iris and the cornea's innermost surface, the endothelium. Hyphema, anterior uveitis and glaucoma are three main pathologies in this area. In hyphema, blood fills the anterior chamber as a result of a hemorrhage, most commonly after a blunt eye injury. Anterior uveitis is an inflammatory process affecting the iris and ciliary body, with resulting inflammatory signs in the anterior chamber. In glaucoma, blockage of the trabecular meshwork prevents the normal outflow of aqueous humour, resulting in increased intraocular pressure, progressive damage to the optic nerve head, and eventually blindness. The depth of the anterior chamber of the eye varies between 1.5 and 4.0 mm, averaging 3.0 mm. It tends to become shallower at older age and in eyes with hypermetropia (far sightedness). As depth decreases below 2.5 mm, the risk for angle closure glaucoma increases. Clinical significance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blind Spot (vision)
A blind spot, scotoma, is an obscuration of the visual field. A particular blind spot known as the ''physiological blind spot'', "blind point", or ''punctum caecum'' in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc.Gregory, R., & Cavanagh, P. (2011)"The Blind Spot" Scholarpedia. Retrieved on 2011-05-21. Because there are no cells to detect light on the optic disc, the corresponding part of the field of vision is invisible. Processes in the brain interpolate the blind spot based on surrounding detail and information from the other eye, so it is not normally perceived. Although all vertebrates have this blind spot, cephalopod eyes, which are only superficially similar, do not. In them, the optic nerve approaches the receptors from behind, so it does not create a break in the retina. The first documented observation of the ...

Visual Field Defect
The visual field is the "spatial array of visual sensations available to observation in introspectionist psychological experiments". Or simply, visual field can be defined as the entire area that can be seen when an eye is fixed straight at a point. The equivalent concept for optical instruments and image sensors is the field of view (FOV). In optometry, ophthalmology, and neurology, a visual field test is used to determine whether the visual field is affected by diseases that cause local scotoma or a more extensive loss of vision or a reduction in sensitivity (increase in threshold). Normal limits The normal (monocular) human visual field extends to approximately 60 degrees nasally (toward the nose, or inward) from the vertical meridian in each eye, to 107 degrees temporally (away from the nose, or outwards) from the vertical meridian, and approximately 70 degrees above and 80 below the horizontal meridian. The binocular visual field is the superimposition of the two monocular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schlemm's Canal
Schlemm's canal is a circular lymphatic-like vessel in the eye. It collects aqueous humor from the anterior chamber and delivers it into the episcleral blood vessels. Canaloplasty may be used to widen it. Structure Schlemm's canal is an endothelium-lined tube, resembling that of a lymphatic vessel. On the inside of the canal, nearest to the aqueous humor, it is covered and held open by the trabecular meshwork. This creates outflow resistance against the aqueous humor. Development While Schlemm's canal has generally been considered as a vein or a scleral venous sinus, the canal is similar to the lymphatic vasculature. It is never filled with blood in physiological settings as it does not receive arterial blood circulation. Schlemm's canal displays several features of lymphatic endothelium, including the expression of PROX1, VEGFR3, CCL21, FOXC2, but lacked the expression of LYVE1 and PDPN. It develops via a unique mechanism involving the transdifferentiation of venous endotheli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciliary Body
The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The aqueous humor is produced in the non-pigmented portion of the ciliary body. The ciliary body is part of the uvea, the layer of tissue that delivers oxygen and nutrients to the eye tissues. The ciliary body joins the ora serrata of the choroid to the root of the iris.Cassin, B. and Solomon, S. ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company, 1990. Structure The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor then flows through the pupil into the anterior chamber. The ciliary bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Germany
East Germany, officially the German Democratic Republic (GDR; german: Deutsche Demokratische Republik, , DDR, ), was a country that existed from its creation on 7 October 1949 until its dissolution on 3 October 1990. In these years the state was a part of the Eastern Bloc in the Cold War. Commonly described as a communist state, it described itself as a socialist "workers' and peasants' state".Patrick Major, Jonathan Osmond, ''The Workers' and Peasants' State: Communism and Society in East Germany Under Ulbricht 1945–71'', Manchester University Press, 2002, Its territory was administered and occupied by Soviet forces following the end of World War II—the Soviet occupation zone of the Potsdam Agreement, bounded on the east by the Oder–Neisse line. The Soviet zone surrounded West Berlin but did not include it and West Berlin remained outside the jurisdiction of the GDR. Most scholars and academics describe the GDR as a totalitarian dictatorship. The GDR was establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Gottingen
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', 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 Church 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 ''universitas'' (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, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A ...

Thüringen
Thuringia (; german: Thüringen ), officially the Free State of Thuringia ( ), is a state of central Germany, covering , the sixth smallest of the sixteen German states. It has a population of about 2.1 million. Erfurt is the capital and largest city. Other cities are Jena, Gera and Weimar. Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" () from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin, a left-bank tributary of the Elbe. Thuringia is home to the Rennsteig, Germany's best-known hiking trail. Its winter resort of Oberhof makes it a well-equipped winter sports destination – half of Germany's 136 Winter Olympic gold medals had been won by Thuringian athletes as of 2014. Thuringia was favoured by or was the birthplace of three key intellectuals and leaders in the arts: Johann Sebastian Bach, Johann Wolfgang von Goethe, and Friedri ...
