Dear Dr. Oyakawa,
Thank you for your suggestion which is the last option. The surgery has lots of uncertainties regarding success rate in bringing the eyes to normal functional state with full binocular vision. So I wanted to know ways by which assessment of the damaged nerve can be done. Also medication or by exercises by which nerve repair and muscle toning can be achieved.

See a strabismus specialist and see if surgery will help the situation.
