    What is Strabismus?

    Understanding About

    Strabismus, often referred to as “crossed eyes” or “lazy eye,” is a common visual disorder affecting millions worldwide. This condition disrupts the normal alignment of the eyes, causing them to point in different directions. Strabismus can manifest in various forms and degrees and typically develops in childhood. Left untreated, strabismus can lead to multiple visual impairments and even impact an individual’s self-esteem and quality of life. Adult-onset strabismus is due to neurological causes or can result from childhood strabismus.

    In strabismus or squint, 1 or both eyes deviate inwards or outwards and appear to be in nonalignment towards the direction of the focused object. It can be due to refractive error, binocular fusion abnormalities, or neuromuscular anomalies of ocular movements.

    If diagnosed and treated early, strabismus has an excellent prognosis. Treatment is usually by refractive error correction, orthoptic exercises, occlusive patching, topical medications, and extraocular muscle surgery.

    Strabismus FAQs


    Strabismus treatment options depend on the type of strabismus— direction of eye turns, angle of deviations, the presence of convergence insufficiency, double vision, or amblyopia (lazy eye), etc.

    Age does have an impact on whether surgery is appropriate.

    Early occurring constant strabismus is the one type of strabismus which might need early surgery to eliminate the eye turn.

    For other types of strabismus, especially intermittent, don’t allow a surgeon to rush you into surgery based on statements about age.

    You should consult an ophthalmologist (eye doctor) who has specialized in squint.

    Yes. Sometimes, large degrees of squint require surgery on both eyes as too much of manipulation on the muscles of one eye is not ideal. This will not affect the other eye.
    In some cases, where the squint occurs because of the refractive error, the squint disappears with the wearing of spectacles. This is especially true of squint that occurs when excess accommodation resulting from hypermetropia (farsightedness) results in a convergent squint.
