A squint, also known as strabismus, is a condition where the eyes don't point in the same direction at the same time. This misalignment can cause one eye to turn inward, outward, upward, or downward. The condition can be present constantly or only noticeable during periods of tiredness or concentration.
Types of Squints:
- Inward squint (esotropia): One or both eyes turn inward.
- Outward squint (exotropia): One or both eyes turn outward.
- Vertical squint (hypertropia or hypotropia): One eye turns upward or downward.
Causes of Squints:
While the exact cause isn't always known, various factors can contribute to the development of a squint. These may include:
- Muscle imbalance: Problems with the eye muscles responsible for controlling eye movement.
- Underlying medical conditions: Certain neurological conditions or syndromes.
- Eye problems: Refractive errors like farsightedness (hyperopia) can sometimes lead to a squint.
- Genetics: A family history of strabismus increases the risk.
Symptoms of a Squint:
- Misaligned eyes: The most obvious symptom is the noticeable misalignment of the eyes.
- Double vision (diplopia): This can occur, especially in adults.
- Eye strain: Difficulty focusing or maintaining eye contact.
- Head tilting: Individuals may tilt their head to reduce double vision.
Treatment for Squints:
Treatment options vary depending on the severity and cause of the squint. They may include:
- Eyeglasses: Correcting refractive errors.
- Eye patches: Strengthening the weaker eye by covering the stronger one.
- Vision therapy: Exercises to improve eye coordination.
- Surgery: To correct muscle imbalances and realign the eyes.
