A weakness in one or more of the muscles of the eye will cause the eye to turn or move away from the normal position. This is commonly known as a squint. A squint can be corrected by surgery, or by using glasses. Rarely, children may grow out of a squint. Surgical correction of squint usually involves a general anaesthetic. In the procedure, the muscles involved are repositioned to correct the alignment. It is important to recognise and treat a squint as, if left uncorrected, it can result in permanent impairment of vision.
