'V' esotropia and excyclotropia after surgery for bilateral fourth nerve palsy

Six patients had residual diplopia at near in the downgaze position after
surgery for bilateral fourth nerve palsy. They all showed a large
excyclotropia in the downgaze position that was associated with a
"V"-pattern esotropia and could not fuse in the reading position because of
the size of the excyclotropia. They were treated with bilateral recessions
of the inferior recti, which resulted in an expansion of the single
binocular field of vision in downgaze, with an elimination of diplopia in
the reading position. None experienced a deterioration in their alignment
in the primary position.
