Brown's syndrome: fusion status and amblyopia.
Many children with Brown's superior oblique tendon sheath syndrome do not have full fusion and stereopsis. Of 28 such patients 8 failed to demonstrate orthophoria in their assumed head position, and many continued to have a head tilt with one or the other eye patched. All eight showed an appropriate vertical deviation, but in addition six showed esotropia and two exotropia. The lack of fusion in their assumed head position led to amblyopia in seven patients.
