What is a common treatment for severe cases of strabismus?

Surgery is a common treatment for severe cases of strabismus because it directly addresses the underlying muscle imbalance that causes the misalignment of the eyes. In strabismus, the extraocular muscles that control eye movement can be too tight or too weak, leading to an inability for the eyes to align properly. Surgical intervention typically involves adjusting the position or tension of these muscles to improve alignment and coordination.

This surgical approach is particularly necessary when other treatments, like corrective lenses or vision therapy, have not resolved the issue. It is designed to improve not only the cosmetic appearance of the eyes but also to enhance binocular vision and depth perception.

In contrast, options like contact lenses and corrective lenses generally focus on refractive errors rather than muscle alignment. Prescription eye drops could serve specific purposes, such as treating conditions like accommodative spasm or certain types of amblyopia, but they are not primarily indicated for the treatment of strabismus itself, especially in severe cases. Thus, while non-surgical options may assist some patients, for those with severe strabismus, surgery is often considered the most effective method for achieving alignment and improving overall visual function.
