Strabismus not only affects appearance but also directly impacts a child's visual development, causing eye strain, reduced vision, distorted perception of objects, and even amblyopia (lazy eye). This condition occurs when the brain "ignores" signals from the weaker eye, potentially leading to permanent vision loss if not treated promptly.

Pathological strabismus does not resolve on its own. The treatment method depends on the cause, condition, and degree of eye misalignment. For strabismus related to refractive errors, doctors may prescribe appropriate glasses. If conservative treatment is ineffective, the angle of strabismus is large, or if it affects vision or causes amblyopia, surgery may be considered to adjust the extraocular muscles, aligning both eyes correctly.

Depending on age and cooperation ability, children may receive local or general anesthesia during surgery. Local anesthesia is typically used for older children who can cooperate and control their emotions, while younger or uncooperative children usually receive general anesthesia.

General anesthesia can cause some temporary side effects such as nausea, dizziness, sore throat, and fatigue. For children under 3 years old, doctors carefully weigh the benefits and risks before recommending it.

Your 6-year-old child has congenital strabismus, making them suitable for surgery under general anesthesia. You should take your child for a comprehensive examination at a hospital with an ophthalmology department for diagnosis and appropriate treatment advice.

Before strabismus surgery, the child undergoes a health check, blood tests, and heart and lung evaluations to ensure they are fit for the procedure. Families need to inform the doctor about the child's medical history, congenital abnormalities, current medications, and any allergies. The child also receives an eye exam, screening for refractive errors, and amblyopia. Based on these results, the doctor develops a suitable treatment plan to optimize effectiveness.

Strabismus occurs when both eyes do not look in the same direction due to a disorder in the coordination of the 6 extraocular muscles. In the first few months of life, infants may experience physiological strabismus as their oculomotor system is not yet fully developed. This condition often improves as the child grows older.

If strabismus persists after 4-6 months of age or appears frequently, it may indicate pathological strabismus, related to congenital factors, refractive errors, or certain neurological conditions. Parents should seek medical attention if both eyes are not aligned, one eye frequently deviates, or if the child often squints, rubs their eyes, experiences headaches, or eye strain. Early detection and treatment help limit the impact on vision and quality of life.
