Alexander Duane
Alexander Duane (September 1, 1858 – June 10, 1926) was an American ophthalmologist who was a native of Malone (town), New York, Malone, New York (state), New York. He studied medicine at the College of Physicians and Surgeons (today the medical school of Columbia University). In 1881 he became an intern at the New York Hospital under German-born ophthalmologist Hermann Jakob Knapp (1832–1911), and in 1884 started his ophthalmological practice in New York. He was with the U.S. Navy during the Spanish–American War and World War I, and for a brief period of time taught classes at Cornell University. Duane is remembered for contributions made in the study of the human eye, eye and vision, including aspects such as refractive error, refraction, accommodation (eye), accommodation and strabismus, squint. He also performed extensive analysis involving movement of the extraocular muscles. In 1897 he published a highly regarded treatise titled "A new classification of the motor anomal ...

Ophthalmologist
Ophthalmology ( ) is a surgery, surgical subspecialty within medicine that deals with the diagnosis and treatment of eye 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 (medicine), residency training specific to that field. This may include a one-year integrated internship that involves more general medical training in other fields such as internal medicine or general surgery. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology. Ophthalmologists prescribe medications to treat 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 an ...

Accommodation (eye)
Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies. In this, distances vary for individuals from the far point—the maximum distance from the eye for which a clear image of an object can be seen, to the near point—the minimum distance for a clear image. Accommodation usually acts like a reflex, including part of the accommodation-vergence reflex, but it can also be consciously controlled. Mammals, birds and reptiles vary their eyes' optical power by changing the form of the elastic lens using the ciliary body (in humans up to 15 dioptres in the mean). Fish and amphibians vary the power by changing the distance between a rigid lens and the retina with muscles. The young human eye can change focus from distance (infinity) to as near as 6.5 cm from the eye. This dramatic change in focal power of the eye of approximately 15 dioptres (the reciprocal of focal length in metres) ...

People From Malone, New York
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 ...

American Ophthalmological Society
The American Ophthalmological Society (AOS) is a medical society of ophthalmologists and the second oldest specialty medical society in the United States, after the New York Ophthalmological Society (founded on March 7, 1864). It was founded on June 7, 1864, by 18 physicians, including Henry Noyes, D. B. St. John Roosa, and Edward Delafield (its first president and also one of the founders of the New York Eye and Ear Infirmary). The society is now based in San Francisco, California. As of 2019, there are approximately 360 active members. Admission to membership in the society is via nomination from current members and the submission of a scholarly thesis, which when approved are published in a peer-reviewed journal, '' The American Journal of Ophthalmology''. A collection of the society's papers are held at the National Library of Medicine. References External links * American Ophthalmological Society Records (1925-c.1940)– National Library of Medicine The United States N ...

Duane's Syndrome
Duane syndrome is a congenital rare type of strabismus most commonly characterized by the inability of the eye to move outward. The syndrome was first described by ophthalmologists Jakob Stilling (1887) and Siegmund Türk (1896), and subsequently named after Alexander Duane, who discussed the disorder in more detail in 1905. Other names for this condition include: Duane's retraction syndrome, eye retraction syndrome, retraction syndrome, congenital retraction syndrome and Stilling-Türk-Duane syndrome. Presentation The characteristic features of the syndrome are: *Limitation of abduction (outward movement) of the affected eye. *Less marked limitation of adduction (inward movement) of the same eye. *Retraction of the eyeball into the socket on adduction, with associated narrowing of the palpebral fissure (eye closing). *Widening of the palpebral fissure on attempted abduction. (N. B. Mein and Trimble point out that this is "probably of no significance" as the phenomenon also oc ...

Ernst Fuchs (doctor)
Ernst Fuchs (14 June 1851, in Vienna – 21 November 1930, in Vienna) was an Austrian ophthalmologist, physician and researcher. Overview The importance of Fuchs' life achievement must surely be based on his discovery and description of numerous ocular diseases and abnormalities. As a result of more than 250 scientific publications, the name Ernst Fuchs became well known throughout the world. Although his name is commonly recognized in conjunction with various corneal and anterior segment disorders, Ernst Fuchs' contribution to ophthalmology exceeds purely the delineation of ocular diseases and the detailed description of signs. Fuchs' collection of microscopic samples laid the foundation for anatomical and pathological understanding of blood vessels, muscles, and most other tissues of the eye. Additionally, Fuchs was able to pass on his unique knowledge, educating ophthalmologists at an international level. His Textbook of Ophthalmology was, for many decades, the most extensivel ...

Extraocular Muscles
The extraocular muscles (extrinsic ocular muscles), are the seven extrinsic muscles of the human eye. Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye and the other muscle, the levator palpebrae superioris, controls eyelid elevation. The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction. Structure Since only a small part of the eye called the fovea provides sharp vision, the eye must move to follow a target. Eye movements must be precise and fast. This is seen in scenarios like reading, where the reader must shift gaze constantly. Although under voluntary control, most eye movement is accomplished without conscious effort. Precisely how the integration between voluntary and involuntary control of the eye occurs is a subject of continuing research."eye, human."Encyclopædia Britannica from Encyclopædia Britannica 2006 Ulti ...

Strabismus
Strabismus is a vision disorder in which the eyes do not properly align with each other when looking at an object. The eye that is focused on an object can alternate. The condition may be present occasionally or constantly. If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth perception. If onset is during adulthood, it is more likely to result in double vision. Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma or infections. Risk factors include premature birth, cerebral palsy and a family history of the condition. Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia or hypotropia where they are vertically misaligned. They can also be classified by whether the problem is present in all directions a person looks (comitant) or varies by direction (incomitant). Diagnosis may be made by obser ...

Refractive Error
Refractive error, also known as refraction error, is a problem with focus (optics), focusing light accurately on the retina due to the shape of the human eye, eye and or cornea. The most common types of refractive error are myopia, near-sightedness, hyperopia, far-sightedness, astigmatism, and presbyopia. Near-sightedness results in far away objects being blurred vision, blurry, far-sightedness and presbyopia result in close objects being blurry, and astigmatism causes objects to appear stretched out or blurry. Other symptoms may include double vision, headaches, and eye strain. Near-sightedness is due to the length of the eyeball being too long, far-sightedness the eyeball too short, astigmatism the cornea being the wrong shape, and presbyopia aging of the lens of the eye such that it cannot change shape sufficiently. Some refractive errors occur more often among those whose parents are affected. Diagnosis is by eye examination. Refractive errors are corrected with eyeglasses, ...

Malone (town), New York
Malone ( moh, Tekanatà:ronhwe) is a town in Franklin County, New York, United States. The population was 14,545 at the 2010 census. The town contains a village also named Malone. The town is an interior town located in the north-central part of the county. History The town was formed from part of the town of Chateaugay in 1805. The town was originally named "Harison", after Richard Harison, who had purchased the land and founded the town. The name was changed in 1808 to "Ezraville", after Ezra L'Hommedieu, and in 1812 to "Malone". During the War of 1812, the village was sacked by British troops making incursions from what would become Canada. Former Governor Mario Cuomo instituted financial measures to increase economic stability to the county by bringing in many prisons (state and federal). Between 1901 and 1958, a commuter train service run by the New York Central Railroad connected Malone with Montreal, Quebec. Notable people * Michael Hastings (1980–2013), i ...
