The diplopia with paralysis of divergence is due to lack of divergence of the eyes which normally occurs when an object is viewed at a distance. This lack of divergence cannot be due to weakness of the external rectus muscles because there is no apparent impairment of their function. The most likely explanation of this disorder is that there is some disturbance of either the convergence or the divergence function. Exactly which of the mechanisms is involved is not yet clear.
