Causes of strabismus - There are two forms of congenital and acquired strabismus. Congenital form develops first 6 months of life and manifests itself acquired up to 3 years. From Duke Peterson Review Program, the most common cause of congenital strabismus is heredity or illness of the mother during pregnancy.
The main cause of acquired strabismus called diseases of the central nervous system, which can develop as a result of physical and mental trauma, also causes include infectious diseases.
Types of strabismus - Types of strabismus defined by Duke Peterson are distinguish because of, the nature of the deviation and stability manifestations because of strabismus is:
Concomitant strabismus - characterized by a total volume of eye movement, as well as lack of ghosting and binocular vision disorders more common in children than in adults.  Paralytic strabismus - a consequence of a violation of functional ability of one or more muscles as a result of any injury, disease of the nervous system or blood vessels.
By the nature of the deviation share:
•    Convergent - eyes directed to the nose
•    Divergent - eyes directed to temple
•    Vertical - eyes directed either downward or upward
•    Mixed - combines the features of several forms
Stability isolated manifestations:
•    Permanent
•    Sometime
Symptoms of strabismus - One of the main features are the appearance of a squint eye, but it is not always reliable, since infant’s strabismus is imaginary. Strabismus in infants can be considered true only if one eye constantly rejected aside, this may be indicative of paralytic strabismus.
