Strabismus is a vision disorder where the eyes do not properly align when looking at an object. It can be present occasionally or constantly. If present during childhood, it can cause amblyopia or loss of depth perception. The two main types are divergent and convergent squint. Divergent squint causes one eye to deviate outward. Signs include outward eye deviation, eye rubbing, and diplopia. Causes are not fully understood but may involve brain or muscle disorders. Treatment options include glasses, patching, eye exercises, and surgery. Convergent squint causes inward eye deviation called esotropia. It can cause lazy eyes and has causes such as diabetes, genetics, or neurological disorders

2. Introduction
 Strabismus is a vision disorder in which the eyes do not properly
align with each other when looking at an object. The eye that is
focused on an object can alternate .The condition may be present
occasionally or constantly .If present during a large part of
childhood, it may result in amblyopia, or lazy eyes, and loss
of depth perception .If onset is during adulthood, it is more likely
to result in double vision.

3. Types of squint
 Divergent squint
 Convergent squint

4. Divergent
Squint
 Exotropia is a manifest divergent squint. The following relates to
concomitant exotropia (angle of deviation the same in all positions
of gaze and regardless of which eye is fixing).
 Divergent squint is a type of squint what causes the deviation of
one eye out.

5. Signs &
Symptoms
• Noticeable outward deviation of eyes
• Rubbing of eyes
• Noticeable when child look at distance
• Diplopia
• Suppression
• No full image is formed

6. Causes
 The causes of exotropia are not fully understood. Six muscles
control eye movement, four that move the eye up and down and
two that move it left and right. All these muscles must be
coordinated and working properly for the brain to see a single
image. When one or more of these muscles does not work
properly, some form of strabismus may occur. Strabismus is more
common in children with disorders that affect the brain such
as cerebral palsy , Down syndrome , hydrocephalus , and brain
tumors . One study has found that children with exotropia are
three times more likely to develop a psychiatric disorder in
comparison with the general population.

7. Treatment
 Glasses
 Patching
 Eye exercise
 Surgery

8. Convergent
squint
 Squint (Strabismus) is misalignment of eyes, where both the eyes
do not look in the same direction.
 In convergent squint the deviating eye is directed inwards towards
the nose; medically termed Esotropia

9. Signs and
Symptoms
 Noticeable converged eyes
 Lazy eyes

10. Causes
 Diabetes
 Family history
 Genetic disorders
 Hyperthyroidism
 Neurological disorders
 Premature birth

11. Treatment
 Glasses
 Surgery
 Therapy
