Vision related query. Department?

I am prematurely born, breech delivery, and having mild Cerebral Palsy, affecting my left leg tendon. Doctor said I have spasticity in my body. I was treated ( operated)  for exotropia in the right eye at the age of 8 years. It has appeared again in the same eye recently. Although it's intermittent, and controllable. It especially occurs during close, concentrated work. Still my vision in both the eyes is 6/6. ?My questions are 1. How it is possible 6/6 vision  in the affected eye? 2. Is this exotropia a case of weak ocular muscle or of mild CP? As my left leg tendon is tight and right eye has minor exotropia, it probably means could be a decent in left part of brain. 3. I have no any other kind of problem. I can do all the activities a normal person can do. So, how I am a candidate of CP! 4. What should I do to correct my minor exotropia? Eye surgery or something related to neurological department? 5. Is exotropia surgery 100% successful Please guide me as I am very much confused.
