There is no cure for the disorder, nor any means to stop its progression. However, the eye is generally otherwise healthy, and glasses (mild disease) and later contact lenses (more severe disease) can greatly improve the vision. In the presence of keratoconus, refractive surgery is contraindicated (not done). In cases where the vision cannot be improved with correction, or if contact lens use is not possible, a corneal transplant is an option. Corneal transplants are generally highly successful after keratoconus, although contact lenses may sometimes still be needed to fully correct the vision. Keratoconus does not recur in a transplant.
Since almost 50% of optic neuritis is likely a result of a post-viral immune reaction, minimizing your risk of acquiring a viral respiratory infection decreases your risk of optic neuritis. It is impossible to totally avoid exposure to respiratory viruses, but research has shown that frequent hand-washing and attempting to not touch one's face without first washing one's hands decreases the incidence of the common cold . Teaching children to cover their mouths and noses when sneezing and instructing them on personal hygiene can also decrease the chances of upper respiratory virus spreading within families.
