Understanding Phoria: Causes, Symptoms, and Treatment Options

Phoria is a type of eye movement that occurs when the eyes are looking straight ahead but the pupils appear to be deviated inward or outward. It is also known as an internuclear ophthalmoplegia.
Phoria can be caused by various factors, including:
* Abnormalities in the nerves that control eye movements
* Injury or stroke to the brain or the nerves that control eye movements
* Certain medications
* Eye muscle imbalance or weakness
* Thyroid disorders

Symptoms of phoria may include:

* Difficulty moving the eyes inward or outward
* Double vision or blurred vision
* Dizziness or vertigo
* Headaches or eye strain

Treatment for phoria depends on the underlying cause and may include:

* Glasses or contact lenses to correct refractive errors
* Prism lenses to help align the eyes
* Eye exercises to strengthen the muscles that control eye movements
* Surgery to realign the eyes or correct abnormalities in the nerves that control eye movements.

It is important to note that phoria can be a symptom of a more serious underlying condition, so if you experience any of these symptoms, it is important to see an eye doctor or a neurologist for proper evaluation and treatment.
