Squinting or strabismus is the misalignment of the eyes which causes diplopia in adult patients and amblyopia in children. This usually happens because of the abnormalities of the neuromuscular control of the eye movement or because of the disorder of the external ocular muscles. Different surgical approaches are used for correcting residual or recurrent strabismus. The nature of the surgery is such that it can be done after general anesthesia and do not require hours of surgery. During the surgery, the surgeon either loosens or tightens the other muscles to make the eye appear straight.
