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 ...
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]
The device has been promoted via influencer marketing and multi-level marketing. Description. Energy medicine devices are a class of pseudoscientific devices that originated with the work of Royal Rife, claiming to work via transferring energy to a person's energy field. The Healy claims to work using electricity to find a user's "personalized ...
Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ophthalmologist. [1] The patient spends only a few hours in the hospital with minimal preoperative preparation. After surgery, the patient should expect soreness and redness but is generally free to return home.
A Cochrane review to examine different types of diagnosis test found only one study. This study used a photoscreener which was found to have high specificity (accurate in identifying those without the condition) but low sensitivity (inaccurate in identifying those with the condition). Several classifications are made when diagnosing strabismus.
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 ...
Peach 2 IPL. Just like the majority of Foreo's buzzy devices, this IPL hair removal tool is extremely high-tech—it even comes with its own app. The tool uses up to 120 flashes per minute and T ...
A delayed-choice quantum eraser experiment, first performed by Yoon-Ho Kim, R. Yu, S. P. Kulik, Y. H. Shih and Marlan O. Scully, [1] and reported in early 1998, is an elaboration on the quantum eraser experiment that incorporates concepts considered in John Archibald Wheeler 's delayed-choice experiment.
Optical aberration. 1: Imaging by a lens with chromatic aberration. 2: A lens with less chromatic aberration. In optics, aberration is a property of optical systems, such as lenses, that causes light to be spread out over some region of space rather than focused to a point. [1]
Pulsed energy projectile or PEP is a technology of non-lethal weaponry. The U.S. military is developing PEP using an invisible laser pulse which ablates the target's surface and creates a small amount of exploding plasma. This produces a pressure wave that stuns the target and electromagnetic radiation that affects nerve cells causing a painful ...
