Eduard Jäger Von Jaxtthal
Eduard Jäger von Jaxtthal (25 June 1818 in Vienna – 5 July 1884 in Vienna) was an Austrian ophthalmologist who was a native of Vienna. He was a professor at the University of Vienna, and was son to oculist Friedrich Jäger von Jaxtthal (1784-1871), and grandson to Georg Joseph Beer (1763-1821). Jäger is remembered for his work involving eye operations, and for his research of ophthalmic disorders. He was an early practitioner of the ophthalmoscope, and was among the first to use ophthalmoscopy to determine refractive error in the eye. Also, he is credited with providing the first description of retinal appearances associated with diabetes. In the 1850s Jäger made improvements to eye chart test types that were earlier developed by Heinrich Küchler (1811-1873). In 1862 Dutch ophthalmologist Hermann Snellen introduced the popular "Snellen chart" for testing visual acuity.H. Snellen, Probebuchstaben zur Bestimmung der Sehschärfe, Utrecht 1862.

Heinrich Küchler
Heinrich Georg Küchler (23 April 1811, Darmstadt – 29 March 1873, Darmstadt) was a German ophthalmologist. From 1828 he studied medicine at the University of Giessen, and after graduation visited Paris for study. In 1834 he returned to Darmstadt, where he started a private ophthalmic practice. In 1836 he was arrested unexpectedly because of his actions in association with a ''Burschenschaft'' (fraternal organization) at Giessen. For nearly three years he was imprisoned, obtaining his freedom in January 1839. After his release, he resumed his ophthalmic practice in Darmstadt.ADB:Küchler, Heinrich – Wikisource at ...

Physicians From Vienna
A physician, medical practitioner (British English), medical doctor, or simply doctor is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases, and their treatment, which is the science of medicine, and a decent competence in its applied practice, which is the art or craft of the profession. Both the role of the physician and the meaning of the word itself vary ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Staff Of The University Of Vienna
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 skill, north of 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 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ophthalmologists
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] |

Aeiou Encyclopedia
Austria-Forum is a freely accessible online collection of reference works on Austria in German language, German, with some articles in English language, English, initiated by Graz University of Technology, TU Graz. As of 2022, Austria-Forum has been integrated with NID-Library (Netinteractive Document Library). Background The predecessor of Austria-Forum, the AEIOU project was launched in 1996 by the Austrian Federal Ministry for Science and Research as part of Austria's millennial celebrations. The first mention of the name ''Ostarrîchi'', or Austria was in the year 996. The content was based on the German-language ''Österreich-Lexikon'', first published in a printed version in 1995. Additional material has been acquired, including additional images and audio and video files, allowing ''AEIOU'' to hrow into one of the first multimedia information systems pertaining to Austrian history, culture and politics.

Pathology
Pathology is the study of disease. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area that includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue (biology), tissue and human cell samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be "Pathophysiology, pathophysiologies"). The suffix ''pathy'' is sometimes used to indicate a state of disease in cases of both physical ailment (as in cardiomyopathy) and psych ...

Visual Acuity
Visual acuity (VA) commonly refers to the clarity of visual perception, vision, but technically rates an animal's ability to recognize small details with precision. Visual acuity depends on optical and neural factors. Optical factors of the eye influence the sharpness of an image on its retina. Neural factors include the health and functioning of the retina, of the neural pathways to the brain, and of the interpretative faculty of the brain. The most commonly referred-to visual acuity is ''distance acuity'' or ''far acuity'' (e.g., "20/20 vision"), which describes someone's ability to recognize small details at a far distance. This ability is compromised in people with myopia, also known as short-sightedness or near-sightedness. Another visual acuity is ''Near visual acuity, near acuity'', which describes someone's ability to recognize small details at a near distance. This ability is compromised in people with hyperopia, also known as long-sightedness or far-sightedness. A com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snellen Chart
A Snellen chart is an eye chart that can be used to measure visual acuity. Snellen charts are named after the Dutch ophthalmologist Herman Snellen who developed the chart in 1862 as a measurement tool for the acuity formula developed by his professor Franciscus_Donders, Franciscus Cornelius Donders. Many ophthalmologists and vision scientists now use an improved chart known as the LogMAR chart. History Snellen developed charts using symbols based in a 5×5 unit grid. The experimental charts developed in 1861 used abstract symbols. Snellen's charts published in 1862 used alphanumeric capitals in the 5×5 grid. The original chart shows A, C, E, G, L, N, P, R, T, 5, V, Z, B, D, 4, F, H, K, O, S, 3, U, Y, A, C, E, G, L, 2. Description The normal Snellen chart is printed with eleven lines of block letters. The first line consists of one very large letter, which may be one of several letters, for example E, H, or N. Subsequent rows have increasing numbers of letters that decrease in s ...
