cyclotropia, a cyclotorsional deviation of the eyes (rotation around the visual axis), particularly when the root cause is an oblique muscle paresis causing the hypertropia. Causes. Hypertropia may be either congenital or acquired, and misalignment is due to imbalance in extraocular muscle function.
Treatment options include eye exercises, wearing an eye patch on alternative eyes, prism correction, and in more extreme situations, surgery or botulinum toxin. If your provider diagnoses swelling or inflammation of, or around the nerve, medicines called corticosteroids may be used.
Depending on the symptoms, the surgical correction of cyclotropia may involve a correction of an associated vertical deviation (hyper- or hypotropia), or a Harada–Ito procedure or another procedure to rotate the eye inwards, or yet another procedure to rotate it outwards.
