Squint or crossed eye is a condition where both eyes do not move together. One eye deviates either inwards, outwards, upwards or downwards while the other eye remains straight. It may also be alternating between the two eyes. It is a condition
which often runs in the family. It can affect one in 50 children under five years old and a successful operation should mean your child's eyes move together. Squinting in adults can also occur if the nerves to the eye muscles, or the
eye muscles themselves, are not working properly causing double vision.
Squint correction is carried out under anesthesia and usually takes about 40 minutes. The surgeon makes a small cut in the surface membrane of your eye and then separates one or more eye muscles from the surface of the eyeball. Using
small dissolvable stitches, we then reattach the muscles, making them tighter or looser than they were before, depending on the correction that needs to be made. Once the operation is complete the eyes will be covered by a patch
and clear plastic shields and you can rest for a while before departure.
Clinical Evaluation At Aayush we ascertain the patient’s perception of the problem. Is a single eye crossed or deviated outward? Which eye is involved? Was the onset gradual or sudden, and has the
problem occurred before? Is the problem stable, improving, or getting worse? Does the patient have diplopia, asthenopia, headaches, or other symptoms? Are there associated signs or symptoms such as ptosis or variability that
might suggest myasthenia gravis? Are there any neurologic concerns? Finally, an understanding of the influence of the condition on activities of daily living is important in helping to counsel the patient regarding treatment
recommendations and prognosis.
Key areas of discussion may include effect on work, driving, relationships, social life, feeling of well-being, and concern for the future. Review of prior treatment records can be helpful, though records from childhood are often
not available. Lack of availability of previous records should not preclude treatment, including surgery.
A comprehensive eye examination, with special emphasis on the ocular motility examination, is indicated for any adult patient for whom strabismus surgery is planned. Examination needs will vary from patient to patient and a one-size-fits-all
approach is not appropriate.
Ocular motility evaluation should include assessment of binocular alignment in the primary position at distance and near, and evaluation of ocular versions at a minimum. For patients with incomitant strabismus, such as that due
to a cranial nerve palsy or restrictive strabismus, assessment of ocular alignment in the secondary and tertiary positions of gaze may be helpful.. In general, quantification of the size of the patient’s deviation should be
done with significant refractive correction in place. The specific techniques of ocular motility evaluation are well known to practicing ophthalmologists, and the reader is referred to standard texts for this information.
Your child should be able to go home the same or following day and you will be advised when they can return to normal activities. Your child will need regular follow-up appointments with the surgeon and eye specialist.
Most children make a good recovery.
It has almost no risks. Most patients do not suffer any complications or side effects but we should mention those complications that can occur:
