Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence of poor vision in one eye. Infantile exotropia (sometimes called "congenital ...
The Four Prism Dioptre Reflex Test (also known as the 4 PRT, or 4 Prism Dioptre Base-out Test) is an objective, non-dissociative test used to prove the alignment of both eyes (i.e. the presence of binocular single vision) by assessing motor fusion. [1] Through the use of a 4 dioptre base out prism, diplopia is induced which is the driving force for the eyes to change fixation and therefore re ...
An Abbe–Koenig prism is a type of reflecting prism, used to invert an image (rotate it by 180°). They are commonly used in binoculars and some telescopes for this purpose. The prism is named after Ernst Abbe and Albert Koenig . The prism is made from two glass prisms, which are optically cemented together to form a symmetric, shallow Vee ...
Raman Tool Set is a free software package for processing and analysis of Raman spectroscopy datasets. It has been developed mainly aiming to Raman spectra analysis, but since it works with 2-columns datafiles (Intensity vs Frequency) it can deal with the results of many spectroscopy techniques. Beyond the spectra preprocessing steps, such as ...
51107174. Correction is a novel by Thomas Bernhard, originally published in German in 1975, and first published in English translation in 1979 by Alfred A. Knopf . Correction’s setting is a garret in the middle of an Austrian forest, described by the narrator as the "thought dungeon" in which the main character, Roithamer, will pursue his ...
This book is mainly centered around algebraic and combinatorial techniques for designing and using error-correcting linear block codes. [1] [3] [9] It differs from previous works in this area in its reduction of each result to its mathematical foundations, and its clear exposition of the results follow from these foundations. [4]
Roof prism. A roof pentaprism used in Single-lens reflex cameras; the lower right face is the roof ( dach ). A roof prism, also called a Dachkanten prism or Dach prism (from German: Dachkante, lit. "roof edge"), is a reflective prism containing a section where two faces meet at a 90° angle, resembling the roof of a building and thus the name.
Bietti's crystalline dystrophy. Bietti's crystalline dystrophy has an autosomal recessive pattern of inheritance. Bietti's crystalline dystrophy (BCD) is a rare autosomal recessive [2] eye disease named after G. B. Bietti. [3] BCD is a rare disease and appears to be more common in people with Asian ancestry.
