Aims and objectives
Brown syndrome is a rare form of strabismus characterized by limitation of elevation of the eyeball on adduction.
In Brown syndrome,
which is mostly congenital but sometimes may be acquired,
the major problem is the lack of relaxation of the superior oblique muscle in elevation on adduction.
Short superior oblique tendon sheath,
short superior oblique tendon,
abnormalities that limit the movement of the superior oblique tendon at the tendon-trochlea complex and the developmental abnormalities of 4th nerve are the possible etiological factors in congenital group.
On the other hand, inflammation at the tendon-trochlea complex,
trauma and infection are claimed to be responsible for the motility problem in acquired Brown syndrome (1-3).
The aim of this case series was to discuss the value of magnetic resonance imaging (MRI) in defining the etiology in patients with acquired Brown syndrome.
