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, orthoptists, and optometrists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [ 1 ]
Strabismus is an eye disorder in which the eyes do not properly align with each other when looking at an object. [2] The eye that is pointed at an object can alternate. [3] The condition may be present occasionally or constantly. [3] If present during a large part of childhood, it may result in amblyopia, or lazy eyes, and loss of depth ...
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 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 or orthoptist or ophthalmologist (medical/surgical eye doctor). It is mainly used in strabismus clinics.
Prism and Base Prism refers to a displacement of the image through the lens, often used to treat strabismus and other binocular vision disorders. The prism value is measured in prism diopters, and Base refers to the direction of displacement. PL is an abbreviation for plano or plain, meaning no prescription
Spectacles (glasses) to correct refractive errors of the eye; not invasive Contact lenses: to correct refractive errors of the eye; a little invasive Phoropter: used in refraction testing Tonometers: used to determine the intraoccular pressure (IOP) - useful in glaucoma; video link for various types of tonometers.

The management of strabismus may include the use of drugs or surgery to correct the strabismus. Agents used include paralytic agents such as botox used on extraocular muscles, [1] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.

The 2 red lights from the right eye are seen on the right side; The 3 green lights from the left eye are seen on the left side; This is recorded as: W4LT (D): 5 lights (Uncrossed Diplopia) ET NB: The clinician will be unable to indicate which eye is the deviating eye based on these results alone.
