Most children eventually recover from amblyopia if they have had the benefit of patches and corrective glasses. Amblyopia has long been considered to remain permanent if not treated within a critical period, namely before the age of about seven years; however, recent discoveries give reason to challenge this view and to adapt the earlier notion of a critical period to account for stereopsis recovery in adults. Eyes that remain misaligned can still develop visual problems. Although not a cure for strabismus, prism lenses can also be used to provide some temporary comfort and to prevent double vision from occurring. Glasses affect the position by changing the persons reaction to focusing. Prisms change the way light, and therefore images, strike the eye, simulating a change in the eye position. Surgery
Strabismus surgery does not remove the need for a child to wear glasses. Currently it is unknown whether there are any differences for completing strabismus surgery before or after amblyopia therapy in children.Strabismus surgery attempts to align the eyes by shortening, lengthening, or changing the position of one or more of the extraocular eye muscles. The procedure can typically be performed in about an hour, and requires about six to eight weeks for recovery. Adjustable sutures may be used to permit refinement of the eye alignment in the early postoperative period. It is unclear if there are differences between adjustable versus non-adjustable sutures as it has not been sufficiently studied. An alternative to the classical procedure is minimally invasive strabismus surgery (MISS) that uses smaller incisions than usual.
A person with an intermittent right esotropia has a right eye that occasionally drifts toward the persons nose, but at other times is able to align with the gaze of the left eye. A person with a mild exophoria can maintain fusion during normal circumstances, but when the system is disrupted, the relaxed posture of the eyes is slightly divergent. Other considerations
Strabismus can be further classified as follows:

Paretic strabismus is due to paralysis of one or several extraocular muscles. Nonparetic strabismus is not due to paralysis of extraocular muscles. Comitant (or concomitant) strabismus is a deviation that is the same magnitude regardless of gaze position. Noncomitant (or incomitant) strabismus has a magnitude that varies as the person shifts his or her gaze up, down, or to the sides.Nonparetic strabismus is generally concomitant. Most types of infant and childhood strabismus are comitant. Paretic strabismus can be either comitant or noncomitant. Incomitant strabismus is almost always caused by a limitation of ocular rotations that is due to a restriction of extraocular eye movement (ocular restriction) or due to extraocular muscle paresis. Incomitant strabismus cannot be fully corrected by prism glasses, because the eyes would require different degrees of prismatic correction dependent on the direction of the gaze. Incomitant strabismus of the eso- or exo-type are classified as "alphabet patterns": they are denoted as A- or V- or more rarely λ-, Y- or X-pattern depending on the extent of convergence or divergence when the gaze moves upward or downward.
