Brown Sndrome Brown Syndrome Brown syndrome is an unusual eye muscle problem where in one or both eyes cannot move fully in toward the nose and upward .
Brown syndrome is an unusual variety of strabismus.
In Brown syndrome, the eye cannot look upward when it is turned inward because of a tightness of the eye muscles. The limited eye movement in Brown syndrome is usually due to a developmentally tight eye muscle, the superior oblique muscle . Other causes of Brown syndrome are acquired and include scar tissue or inflammation in the superior oblique muscle or the superior oblique tendon attached to the eye. It is important to note that Brown syndrome is caused by a restriction and not a weakness of the muscle that elevate the in-turned eye. The inability of the superior oblique muscle to relax is the most common cause of restriction .
