What is a Phoria?
Understanding Phorias. A phoria is a misalignment of the eyes that only appears when binocular viewing is broken and the two eyes are no longer looking at the same object. The misalignment of the eyes starts to appear when a person is tired, therefore it is not present all of the time. A phoria can be diagnosed by conducting the cover/cover test.

Medicines, such as prochlorperazine and some antihistamines, can help in the early stages or most cases of vertigo. Many people with vertigo also benefit from vestibular rehabilitation training (VRT), which is a series of exercises for people with dizziness and balance problems.
Why am I seeing vertical lines in my vision?
Causes. Most floaters are flecks of collagen that come from the gel-like substance in the back of the eye called the vitreous. As you get older, these collagen fibers shrink and clump together. The floaters are actually the shadows they cast on your retina.

Vertical heterophoria symptoms are often not constant. You may go hours or even days without feeling any symptoms at all, before sudden onset leaves you feeling disoriented and sick.
Does vertical heterophoria impact driving?
Binocular vision dysfunction, including VH, can sometimes make people feel anxious when driving, because their peripheral vision tricks them into feeling as though objects that are stationary are actually in movement.
Can vertical heterophoria be misdiagnosed?
It is quite common for VH to be misdiagnosed as a disorder of the inner ear, migraine issues, multiple sclerosis or vertigo. This is because VH symptoms often imitate the symptoms of these disorders, and are not problems that are naturally associated with a vision condition.
How is vertical heterophoria treated?
Treatment of VH involves correction of the misalignment. There are a few ways your eye doctor may go about helping with this.
What is a misalignment of the eyes that only appears when binocular viewing is broken?

How does vertical hematophyria affect the vestibular system?
Vertical Heterophoria can also affect the vestibular system, disrupting one’s sense of balance. When your body feels off-balance, you’re more likely to fall. This can make what should be effortless actions – such as stepping off curbs, going up the stairs or even transitioning between surfaces as you walk – perilous.

What does phoria mean?
phoria. [ for´e-ah] any tendency to deviation of the eyes from the normal when fusional stimuli are absent or fusion is otherwise prevented; a latent or usually unmanifested tropia; see also heterophoria.
What is the relative direction assumed by the eyes during binocular fixation of a given object in the absence of
The relative directions assumed by the eyes during binocular fixation of a given object in the absence of an adequate fusion stimulus. See: cyclophoria, esophoria, exophoria, heterophoria, hyperphoria, hypophoria, orthophoria.
What causes diplopia in the right eye?
Torsional diplopia can be relieved by an angular tilt of the head to the right or left shoulder.
What is forced duction test?
The forced duction test can be used to differentiate between limitation of eye movement from denervation of the agonist eye muscle and tethering of the antagonist eye muscle. If the examiner cannot move the globe in the direction of gaze limitation, forced ductions are said to be positive and it can be assumed that there is a mechanical or restrictive component.
What is the law of projection of images?
This law establishes that an object that forms its image on any point in the retina is projected to a point in visual space directly opposite , and when a distant object is viewed with two normally seeing eyes, the visual axes are parallel. Conjugate gaze up and to the right, for example, is accomplished by conjugate movement of the eyes to the right and simultaneous and equal innervation to the right SR and the left IO muscles. Each EOM moves the eye in the same distance and at the same speed to attain precise "foveation." If there is an interocular difference in the speed or extent of eye movement, the fixational target falls on non-corresponding points in the retina and diplopia results. It follows that conjugate movement of the eyes further into the field of the weakened eye muscle will increase the amount of retinal non-correspondence and, therefore, increase the distance between disparate images.
Which muscle moves the eye vertically?
Underaction of the superior or inferior rectus muscles, which primarily moves the eye in a vertical plane, is compensated for by chin flexion or extension. Figure 4. Anomalous head position in a person with a right superior rectus muscle palsy. Top: Right eye does not elevate normally in abduction.
What happens if the vertical deviation increases with right head tilt?
If the vertical deviation increases with right head tilt (which reflexly causes incyclodeviation of the right eye and excyclodeviation of the left eye) the right SO must be underacting; if the hyperdeviation increases on left head tilt, the left superior rectus is underacting. The explanation is simple.
What is a three step eye test?
The three-step test simply is a variation of the cover-uncover test. It will quickly and accurately provide the diagnosis of a weakened vertical eye muscle. Each step reduces by one-half the number of muscles that could possibly be causing the vertical imbalance.
What angle does the SR attach to the globe?
It courses forward at an angle of 23 degrees to the medial wall of the orbit and attaches to the globe superiorly. With the eye abducted 23 degrees, the plane of the SR parallels the vertical anterior-posterior plane of the globe. In this position, contraction of the SR elevates the eye.
