Prism therapy (if tolerated, to manage diplopia) Vision Therapy. Patching (mainly to manage amblyopia in children and diplopia in adults) Botulinum toxin injection. Surgical correction. Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the cosmetic defect.
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 and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1] Manifest is defined by the eye deviating constantly or intermittently ...
Certain abbreviations are current within the profession of optometry. They are used to denote clinical conditions, examination techniques and findings, and various forms of treatment.
Congenital fourth nerve palsy is a condition present at birth characterized by a vertical misalignment of the eyes due to a weakness or paralysis of the superior oblique muscle.
Strabismus can occur due to muscle dysfunction, farsightedness, problems in the brain, trauma, or infections. [3] Risk factors include premature birth, cerebral palsy, and a family history of the condition. [3] Types include esotropia, where the eyes are crossed ("cross eyed"); exotropia, where the eyes diverge ("lazy eyed" or "wall eyed"); and hypertropia or hypotropia where they are ...
The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. [1] Dissociation of the deviation is brought about by presenting a red line image to one eye and a white light to the other, while prisms are used to superimpose these and effectively measure ...
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. Through this test, suppression, microtropia, diplopia and manifest deviations can be noted. However this test should ...
Depending on the symptoms, the surgical correction of cyclotropia may involve a correction of an associated vertical deviation ( hyper- or hypotropia ), or a Harada–Ito procedure [14] or another procedure [15] to rotate the eye inwards, or yet another procedure to rotate it outwards. [16]
Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions. The most common application for this is the treatment of strabismus. By moving the image in front of the deviated eye, double vision can be avoided and ...
Skew deviation is an unusual ocular deviation ( strabismus ), wherein the eyes move upward ( hypertropia) in opposite directions. Skew deviation is caused by abnormal prenuclear vestibular input to the ocular motor nuclei, most commonly due to brainstem or cerebellar stroke.
