Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]
Exophoria. Exophoria is a form of heterophoria in which there is a tendency of the eyes to deviate outward. [1] During examination, when the eyes are dissociated, the visual axes will appear to diverge away from one another. [2] The axis deviation in exophoria is usually mild compared with that of exotropia .
Vishaka and Ors. v. State of Rajasthan was a 1997 Indian Supreme Court case where various women's groups led by Naina Kapur and her organisation, Sakshi filed Public Interest Litigation (PIL) against the state of Rajasthan and the central Government of India to enforce the fundamental rights of working women under Articles 14, 19 and 21 of the Constitution of India.
Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called ...
The strength of the prism is increased until the streak of the light passes through the centre of the prism, as the strength of the prism indicates the amount of deviation present. The Maddox rod is a handheld instrument composed of red parallel plano convex cylinder lens , which refracts light rays so that a point source of light is seen as a ...
Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause. Causes include: Refractive errors; Divergence insufficiency; Convergence excess; this can be due to nerve, muscle, congenital or mechanical anomalies.
Specialty. Neurology, ophthalmology. 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.
v. t. e. Rajasthani literature is an tradition in Indian literature dating to the 2nd millennium, which includes literature written in the Rajasthani language. An early form of Rajasthani started developing in the 11th century from Saurseni Prakrit as Maru-Gurjar or Gurjar Apabhramsa . Early Rajasthani literature was usually written by Charans.
The prism cover test ( PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. [1] It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
Māru-Gurjara architecture, or "Solaṅkī style" is a distinctive style that began in Rajasthan and neighbouring Gujarat around the 11th century, and has been revived and taken to other parts of India and the world by both Hindus and Jains. This represents the main contribution of the region to Hindu temple architecture.
