Treatment

Many cases of adult squint recover spontaneously within a period of three to six months. Once the cause of the squint has been investigated, the immediate treatment entails eliminating the diplopia by occluding one or other eye. This can be conveniently achieved by applying adhesive tape to the spectacle lens. If the angle of the squint is sufficiently small, it might be possible to regain binocular vision by means of a prism. Fresnel prisms are thin and flexible and can be simply stuck onto the spectacle lens as a temporary measure during the recovery period. When the squint shows no sign of recovery over a period of nine months or more, surgery is usually required to restore binocular vision. Before applying these principles of management, it is essential to treat the underlying cause of the squint. It would be a serious error to treat diplopia because of raised intracranial pressure by means of prisms, without instituting a full neurological investigation, just as it would not help the patient with myasthenia gravis to undergo squint surgery before medical treatment has been started.
