51
Poorly controlled diabetes mellitus is a significant risk factor for an abducens nerve palsy. True False
t
52
Abducens nerve palsy results in an inability of the abducens nerve to transmit signals to the lateral rectus, resulting in an inability to adduct the eye and horizontal diplopia. True False
t
53
Dysfunction of the abducens nerve can occur at any point of its transit from the pons to the lateral rectus muscle, resulting in sixth nerve palsy. True False
