- BD: base down prisms - BU: base up prisms - BO: base out prisms - BI: base in prisms - eso: esotropia - exo: exotropias - L/R: left hypertropia or right hypotropia - R/L: right hypertropia or left hypotropia Double Maddox rod test. The double Maddox rod test can also be used to assess torsion and measure cyclotropias.
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.
When measuring horizontal fusion ranges, base in prisms assess fusional divergence while base out prisms assess fusional convergence. The vertical fusional vergence amplitude can also be measured with base up and base down prisms although the horizontal PFR is typically the main focus when testing.
One of greatest climbing guides on Mount Everest has scaled the world's highest peak for the 29th time, extending his own record for most times to the summit, expedition organizers said Sunday ...
Specialty. Ophthalmology. 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 ...
Amblyopia. Anisometropia is a condition in which a person's eyes have substantially differing refractive power. [1] Generally, a difference in power of one diopter (1D) is the threshold for diagnosis of the condition . [2] [3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye ...
Prism adaptation. Prism adaptation is a sensory-motor adaptation that occurs after the visual field has been artificially shifted laterally or vertically. It was first introduced by Hermann von Helmholtz in late 19th-century Germany as supportive evidence for his perceptual learning theory (Helmholtz, 1909/1962). [1]
GameBox 1.0 (2004) – Directed by David Hillenbrand & Scott Hillenbrand. A video game tester must fight to escape from a video game that has become all too real. Satan's Little Helper (2004) – Directed by Jeff Lieberman. A nine-year old gamer mistakes a costumed killer for a video game version of the Devil.
James Todd Smith (born January 14, 1968), known professionally as LL Cool J (short for L adies L ove Cool J ames), [3] is an American rapper, songwriter, record producer, and actor. [4] He is one of the earliest rappers to achieve commercial success, alongside fellow new school hip hop acts Beastie Boys and Run-DMC .
Because of this, the masses in a free-fall configuration do not orbit in a closed "loop", but travel forward and backward along an open "track". In 2023, Ivan Hristov, Radoslava Hristova, Dmitrašinović and Kiyotaka Tanikawa published a search for "periodic free-fall orbits" three-body problem, limited to the equal-mass case, and found 12,409 ...
