Surgery

In severe cases, surgery may be needed. Eye surgery can be performed to improve the appearance of an eye turn, usually in cases of cross-eyes or eyes that point in different directions. Surgery may be required on the muscles of your eyes.
Conclusion
Amblyopia can be very severe and can result in vision impairment or total blindness. However, it is very treatable, especially when caught at an early stage. This is why it is important that one pays attention to the symptoms and immediately visit a medical doctor if in suspicion of any of the signs.
