This test is performed on patients suspected to have small angle deviations of less than 10 prism dioptres, a microtropia, that may or may not have been observed on cover test because of subtle eye movements. The test determines whether the patient has bifoveal fixation or monofixation despite their eyes seeming straight. [2]
Videonystagmography (VNG) is a type of testing used to assess vestibular and central nervous system function through the use of eye movement tracking, specifically evaluating nystagmus. [1] The older version of technology used to performed these tests, known as electronystagmography (ENG), leverages electrophysiological signals.
The unilateral cover test is performed by having the patient focus on an object then covering the fixating eye and observing the movement of the other eye. If the eye was exotropic , covering the fixating eye will cause an inwards movement; and if esotropic , covering the fixating eye will cause an outwards movement.
Pupillary constriction is tested for on the eye examined (direct response) and on the opposite eye (consensual response). The swinging flashlight test involves moving the light between the two pupils. Normally both direct and consensual responses are elicited when the light shines on an eye, and some dilation will occur during the swing between.
An eye examination, commonly known as an eye test, [1] is a series of tests performed to assess vision and ability to focus on and discern objects. [2] It also includes other tests and examinations of the eyes. [2] Eye examinations are primarily performed by an optometrist, ophthalmologist, or an orthoptist.
The results from this method of assessment rely on the patient's responses, and are therefore subjective. The assessment should also be performed objectively, in which the examiner observes the eye's movement behind the prism, anticipating the break point at which the eye can no longer make a vergence movement to maintain BSV.
