Inheritance of DRS:

In diffrent types of DRS is inherited by autosomal dominant or autosomal dominant.  The percnetage of DRS effecting girls to boys is 60% to 40%.  It would effect either one eye or both.  And it usually effect the left eye (Strabismus 1).   

Symptoms of DRS:

Common symptoms of DRS types are: blindness, tearing and diplopia (Strabismus 1). 

Detection of DRS:

Screening test could be run to test light reflexes.  If tropia is present, the light reflex will be displaced in the deviating eye.  If light reflex lateral to pupil then it is esotropia.  If light reflex medial to pupil then it is exotropia (Strabismus 1).

Treatment of DRS:

When looking straight ahead, if your eyes are both position in normal position, then surgery can't be done to fix.  But when looking ahead and they are not in normal position, then surgery can be done to fix your eye's musceles.  Patching the normal eye would make the amblyopic eye to work.  To treat hyperopia you would wear glasses to accomadate esotropia (Strabismus 1).
