Question
An eight-year-old girl recently experienced a decline in her vision and was diagnosed with congenital strabismus after a hospital examination. The parents are concerned about the possibility of treating this condition.
Answer
Congenital strabismus is often related to family heredity, occurring commonly at birth or within the first six months after birth, and it tends to have larger deviation angles. It often manifests as downgaze refractive errors and cannot be corrected solely with glasses. Due to the lack of innate binocular vision conditions, it has a significant impact on visual function. In treatment, surgical therapy adjusts the strength and attachment points of the extraocular muscles to achieve the gradual normalization of eye position. Congenital esotropia and exotropia usually require surgical treatment, as do non-correctional and highly deviated strabismus, which often need to be corrected through surgical methods.
