  2. Duane syndrome - Wikipedia

    en.wikipedia.org/wiki/Duane_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. [2] Other names for ...

  3. Convergence insufficiency - Wikipedia

    en.wikipedia.org/wiki/Convergence_insufficiency

    The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others. In some cases, difficulty ...

  4. Diplopia - Wikipedia

    en.wikipedia.org/wiki/Diplopia

    Diplopia is the simultaneous perception of two images of a single object that may be displaced horizontally or vertically in relation to each other. [1] Also called double vision, it is a loss of visual focus under regular conditions, and is often voluntary. However, when occurring involuntarily, it results from impaired function of the extraocular muscles, where both eyes are still functional ...

  5. Horror fusionis - Wikipedia

    en.wikipedia.org/wiki/Horror_fusionis

    In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia. Even when the double vision images are made to nearly overlap using optical means such as prisms ...

  6. Talk:Prism correction - Wikipedia

    en.wikipedia.org/wiki/Talk:Prism_correction

    I removed the Prentice rule example, because it is not written for a nonspecialist audience. As it was it was incomprehensible to anyone not familiar with the specialized terminology and notation of optometry. It could perhaps be included if rewritten in plain English, without assuming specialized knowledge.-- Srleffler ( talk) 06:57, 2 June 2013 (UTC) [ reply]

  7. Time base correction - Wikipedia

    en.wikipedia.org/wiki/Time_base_correction

    Time base correction. Time base correction (TBC) is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media. Without time base correction, a signal from a videotape recorder (VTR) or videocassette recorder (VCR), cannot be mixed with other, more time-stable devices found in ...

  8. Sheppard's correction - Wikipedia

    en.wikipedia.org/wiki/Sheppard's_correction

    Sheppard's correction. In statistics, Sheppard's corrections are approximate corrections to estimates of moments computed from binned data. The concept is named after William Fleetwood Sheppard . Let be the measured kth moment, the corresponding corrected moment, and the breadth of the class interval (i.e., the bin width).

  9. C (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_(programming_language)

    C is an imperative procedural language, supporting structured programming, lexical variable scope, and recursion, with a static type system. It was designed to be compiled to provide low-level access to memory and language constructs that map efficiently to machine instructions, all with minimal runtime support. Despite its low-level capabilities, the language was designed to encourage cross ...
