What is Strabismus or Wandering Eye/Cross-Eye?
Normally, the eyes are aligned with one another when looking in any direction. When this alignment is disrupted it is known as strabismus.
This misalignment can be in one or both eyes. The most common form of strabismus is both eyes looking inwards, but looking outwards, to the sides or downwards is also possible.

What is Psuedo-strabismus?
This is not true strabismus. When the bridge of a baby's nose is wide it can look like the eyes are pointing inwards. It does not require treatment. As the child grows this misleading appearance will correct itself.

What is Latent Strabismus?
Normally, this cannot be identified externally. It can only be revealed through examination. Headaches, eye strain and rapid fatigue while reading can point to latent strabismus.

What Causes Strabismus?
Strabismus can be caused by such reasons as:
•    Eye diseases such as congenital cataracts from birth and far-sightedness (hypermetropia)
•    Family history of cross-eye (genetic)
•    Premature birth
•    Incest
•    High fevers and seizures
•    Trauma

What are the symptoms of Strabismus?

•    Diplopia
•    Head or eye tilting one side
•    Closing one eye at sunlight
•    Difficulty in reading

Can Strabismus Occur in Old Age?
Strabismus can sometimes occur in young people and in old age. In such cases the reason is paralysis of the nerves that move the eye muscles. The patient suddenly starts seeing double. The most common causes are trauma, meningitis, diabetes, hypertension and brain tumors.

How is Strabismus Treated?
First of all, the type of strabismus is identified and then its severity. There are various different treatments depending on the type of strabismus.
Glasses: If accompanied by astigmatism glasses must be worn.
Eye Patching: If accompanied by amblyopia (lazy eye) treatment takes the form of eye patches.
Surgery: Surgery is performed when the problem cannot be rectified using glasses.

What is Amblyopia?
This causes a reduction in vision by at least 20% even when wearing glasses. If not treated early this problem can last the patient's life.
Amblyopia is caused by such reasons as:
•    Strabismus
•    Congenital cataract
•    Congenital eyelid droop
•    Uncorrected astigmatism

How is Amblyopia Treated?
First of all, the reason creating amblyopia must be eliminated. For example, if the amblyopia is the result of congenital cataract, cataract surgery must be carried out urgently and eye-patch treatment applied.

Glasses: Astigmatism is corrected with glasses. If there is a large degree of astigmatism between both eyes, contact lenses must be worn.

How is Eye-Patch Treatment Carried Out?
This works on the principle of covering up the good eye and forcing the inferior eye to work. Among children aged 3-7 if amblyopia is severe the good eye is covered for up to 6 hours, or 2 hours in the case of light to mild amblyopia.
Eye-patch treatment works better in the pre-school period and is less effective among children aged 7-12. There is no successful treatment for adults

Congenital Tear Duct Blockage:
A build up of water in one or both eyes starting in one or both eyes in babies usually aged 3 weeks can lead to conjunctivitis.
Treatment consists of massaging the bridge of the nose (4 times a day for 15 seconds a time) until the age of 1, and antibiotic eye drops in cases of conjunctivitis. If the ducts do not open by the time the infant is 1 year old, surgery under general anesthetic is performed to open up the affected duct/ducts.
