Strabismus left untreated may either worsen or remain stable. Strabismus is a common eye condition where the eyes do not look in the same direction. When one eye looks directly at an object, the other eye may be misaligned. Depending on the direction of the misalignment, strabismus can be classified into different types such as esotropia, exotropia, and hypertropia. Moreover, based on the different causes of strabismus, it can be divided into accommodative strabismus, paralytic strabismus, concomitant strabismus, and restrictive strabismus. Patients need to visit the ophthalmology department of a hospital for a comprehensive strabismus examination to diagnose the specific type of strabismus, and then receive the corresponding treatment to improve symptoms. For example, accommodative strabismus can be corrected with glasses to adjust refractive errors, thereby eliminating the symptoms of strabismus, while non-accommodative strabismus may require surgical treatment for a cure.
