Four prism dioptre reflex test

Index Four prism dioptre reflex test

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]

Amblyopia

Amblyopia, also called lazy eye, is a disorder of sight due to the eye and brain not working well together.

Anisometropia

Anisometropia is the condition in which the two eyes have unequal refractive power.

Bagolini Striated Glasses Test

Bagolini striated glasses test, or BSGT, is a subjective clinical test to detect the presence or extent of binocular functions and is generally performed by an Optometrist(O.D) or orthoptist or ophthalmologist (medical/surgical eye doctor, M.D. or D.O.). It is mainly used in strabismus clinics.

Binocular vision

In biology, binocular vision is a type of vision in which an animal having two eyes is able to perceive a single three-dimensional image of its surroundings.

Diplopia

Diplopia, commonly known as double vision, is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, diagonally (i.e., both vertically and horizontally), or rotationally in relation to each other.

Hering's law of equal innervation

Hering's law of equal innervation is used to explain the conjugacy of saccadic eye movement in stereoptic animals.

Horopter

In studies of binocular vision the horopter is the locus of points in space that have the same disparity as fixation.

Monofixation syndrome

Monofixation syndrome (MFS) (also: microtropia or microstrabismus) is an eye condition defined by less-than-perfect binocular vision.

Random dot stereogram

Random-dot stereogram (RDS) is stereo pair of images of random dots which when viewed with the aid of a stereoscope, or with the eyes focused on a point in front of or behind the images, produces a sensation of depth, with objects appearing to be in front of or behind the display level.

Stereopsis

Stereopsis (from the Greek στερεο- stereo- meaning "solid", and ὄψις opsis, "appearance, sight") is a term that is most often used to refer to the perception of depth and 3-dimensional structure obtained on the basis of visual information deriving from two eyes by individuals with normally developed binocular vision.

Worth 4 dot test

The Worth Four Light Test, also known as the Worth's Four Dot test or W4LT, is a clinical test mainly used for assessing a patient's degree of binocular vision and binocular single vision.
