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 ...

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] |

Franco-Prussian War
The Franco-Prussian War or Franco-German War, often referred to in France as the War of 1870, was a conflict between the Second French Empire and the North German Confederation led by the Kingdom of Prussia. Lasting from 19 July 1870 to 28 January 1871, the conflict was caused primarily by France's determination to reassert its dominant position in continental Europe, which appeared in question following the decisive Austro-Prussian War, Prussian victory over Austria in 1866. According to some historians, Prussian chancellor Otto von Bismarck deliberately provoked the French into declaring war on Prussia in order to induce four independent southern German states—Grand Duchy of Baden, Baden, Kingdom of Württemberg, Württemberg, Kingdom of Bavaria, Bavaria and Grand Duchy of Hesse, Hesse-Darmstadt—to join the North German Confederation. Other historians contend that Bismarck exploited the circumstances as they unfolded. All agree that Bismarck recognized the potential for new ...

Eye Chart
__NOTOC__ An eye chart is a chart used to measure visual acuity comprising lines of optotypes in ranges of sizes. Optotypes are the letters or symbols shown on an eye chart. Eye charts are often used by health care professionals, such as optometrists, physicians and nurses, to screen persons for vision impairment. Ophthalmology, Ophthalmologists, physicians who specialize in the eye, also use eye charts to monitor the visual acuity of their patients in response to various therapies such as Eye drop, medications or Eye surgery, surgery. The chart is placed at a standardized distance away from the person whose vision is being tested. The person then attempts to identify the optotypes on the chart, starting with the larger ones and continuing with progressively smaller ones until the person cannot identify the optotypes. The size of the smallest optotypes that can be reliably identified is considered the person's visual acuity. The Snellen chart is the most widely used. Alternative ...

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] |
Staphyloma
A staphyloma is an abnormal protrusion of the uveal tissue through a weak point in the human eye, eyeball. The protrusion is generally black in colour, due to the inner layers of the eye. It occurs due to weakening of outer layer of eye (cornea or sclera) by an inflammatory or degenerative condition. It may be of five types, depending on the location on the eyeball (''bulbus oculi''). Anterior (corneal) staphyloma In the anterior segment of the eye, involving the cornea and the nearby sclera. It is an ectasia and outpouching of the pseudocornea ( the scar formed from organised exudates and fibrous tissue covered with epithelium over the iris) which results after total sloughing of cornea in sloughening corneal ulcer with iris plastered behind; the pseudocornea, being too weak to resist the IOP protrudes forward with the uveal tissue. This is known as anterior staphyloma. Intercalary staphyloma It is the name given to the localised bulge in limbal area, lined by the root of th ...

Grand Duchy Of Hesse
The Grand Duchy of Hesse and by Rhine () was a grand duchy in western Germany that existed from 1806 to 1918. The grand duchy originally formed from the Landgraviate of Hesse-Darmstadt in 1806 as the Grand Duchy of Hesse ().

Colloquially, the grand duchy continued to be known by its former name of Hesse-Darmstadt. In 1806, the Landgraviate of Hesse-Darmstadt seceded from the Holy Roman Empire and joined Napoleon's new Confederation of the Rhine.
