Squint (Strabismus) occurs when the eyes are not accurately aligned and point in different directions while focussing on an object. It is generally known as ‘turned,’ ‘lazy’ or ‘crossed’ eyes.
In Squint, one eye or both eyes may turn either inward (esotropia), outward (exotropia), upward (hypertropia) or downward (hypotropia). Squint may be constant or intermittent. While the causes of Squint are not fully understood, it is known that an abnormality in the muscles and/or under developed vision in one or both eyes are the contributing factors.
Early diagnosis of Squint (Strabismus) is essential in preventing irreparable vision loss later in life. Squint treatment aims to enhance the alignment of the eyes and to correct the resulting vision loss (amblyopia). Squint and amblyopia can be treated with combination of glasses, eye patching and/or surgery.
Surgery includes treating one or more of the eye muscles to correct the position of the eye(s). The treatment is performed under local/general anesthesia in operation theatre. Now a days squint is treated with latest fornix method, leading no/ minimal scarring. this is a day care procedures and patient may resume his/her routine activities from the very next day.
The management of squint is planned into two stages depending upon presence of refractive error and/or muscle weakness. first of all, a complete evaluation is done to see if there is any need of specs. We might see improvement in squint after proper use of prescription glasses. In second stage if the squint is not fully corrected even after using prescription glasses strabismus surgery for balancing of muscles is planned.
As such, squint surgery does not enhance vision and instead aligns the eye. Aligning the retina is critical for treating amblyopia (lazy eyes) in children that actually in a way helps in improving the vision of kids. This does, however, actually improves cosmesis in adults.
Squint may re-appear sometimes in later ages, which had been operated earlier. It needs to be thoroughly evaluated and accordingly a re-surgery may be needed.
