What is decompensation of a phoria?
Any latent binocular misalignment that becomes symptomatic is considered to be a phoria that has “decompensated.” Symptoms of decompensated esophoria may range from simple headache to severe asthenopia and diplopia.
How is Decompensating exophoria treated?
Some common treatment methods include: Glasses. You can get special glasses that have prisms in the lenses. These prisms can help reverse the outward eye movement of exophoria and lessen eye strain.
How can we manage heterophoria?
Management of Heterophoria: Basic Principles
- Remove the cause of decompensation.
- Refractive correction or modification.
- Give eye exercises.
- Prescribe prism relief.
- Refer to another practitioner.
How is decompensated phoria diagnosed?
A battery of tests is required to diagnose decompensated heterophoria, including cover test, aligning prism (associated phoria), fusional reserves, and foveal suppression or stereoacuity. These tests, and sensitivity and specificity, are summarised.
What causes decompensated phoria?
Monocular diplopia is often caused by a problem in your cornea or the lens in your eye. Double vision that is only when both eyes are open is coming from a problem with the eye muscles. Many times true double vision is happening due to the eye muscles getting weaker as we age. We call this a decompensating phoria.
What is the meaning of phoria?
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.
What causes phoria?
Phorias or tropias can be caused by a variety of factors. One of the most common causes is having a large amount of hyperopia or farsightedness. 3 When young children have high amounts of farsightedness that is undiagnosed, they struggle to see clearly.
What is the treatment for exotropia?
HOW IS EXOTROPIA TREATED? Non-surgical treatment may include glasses and in some instances, patching therapy may be recommended. If the eyes are misaligned more often than they are straight, surgery on the eye muscles may be recommended in order to realign the eyes.
What causes a phoria?
How is phoria measured?
Phoria is determined by suspending fusion with an infrared filter. Response AC/A is assessed by simultaneously measuring accommodation with the Canon R-1 autorefractor for targets at 0, 2, and 4 D in a Badal optometer. This study assesses the repeatability and validity of this new technique.
