This is usually a manifestation of vertical strabismus, which can be caused by two factors: 1) congenital developmental factors, for which surgical correction is required and should be done as early as possible to avoid affecting the development of stereo visual function in both eyes; 2) acquired factors, such as orbital diseases, masses, nerve palsy or eye trauma. In this case, it is recommended to clarify the specific cause of the disease and treat the cause symptomatically. After conservative treatment, if it does not improve, then surgical correction should be considered. This surgery is a very routine procedure in ophthalmology, in which the starting and ending points of the extraocular muscles are surgically changed to correct the eye position. Therefore, if the above-mentioned symptoms are present in the eye, it is important to go to the hospital as soon as possible for a detailed examination to clarify the cause and give active treatment.
