Strabismus treatment aims to improve the alignment of the eyes and restore proper vision. Treatment of strabismus or 'crossed eyes' may include patching, eyeglasses, orthoptic therapy or muscle surgery.
Early diagnosis is critical in preventing the vision loss that occurs as a result of amblyopia, also known as lazy eye.
On this page, we cover what causes strabismus, the symptoms of strabismus and how it is treated.
Causes of lazy eye
A squint (strabismus)
This is the most common cause and it means that the eyes are not parallel when they focus on an object. You will notice that each eye looks in a different direction and the child will experience double or blurred vision. They will unconsciously suppress the image from one eye, causing it to become lazy.
Some squints will not be obvious and need to be diagnosed by an ophthalmologist.
Poor vision in one eye (refractive error)
If the vision in one eye is stronger than the other, a child will use the good eye and suppress the image from the weaker eye. This can be corrected with glasses but often requires further treatment to correct the amblyopia.
An example of this would be an eye tumour. Serious cases like this are rare, but they underline the importance of eye exams for young children.

FAQs about strabismus
Most adults with strabismus have had the condition since childhood. Although it may start later in life.
- Head injury may cause damage to the eye muscles
- Chronic health conditions such as diabetes or stroke
- Brain tumour
Surgery for strabismus involves repositioning the eye muscles to help the eyes point in the same direction.
Amblyopia is a condition that develops when a weak or lazy eye moves inwards or outwards, resulting in decreased vision in one eye. If left untreated, it can lead to permanent vision loss.
