Paralytic strabismus.

This review of the year's literature on paralytic strabismus contains some especially interesting contributions on epidemiology of ischemic ocular motor palsies, new imaging diagnostic techniques in sixth and fourth nerve palsy and in Graves' ophthalmopathy, and bilateral histological findings in one case of clinically monolateral Duane's retraction syndrome. Some reports concern the reliability of diagnostic tests routinely used for measuring cyclotorsion in superior oblique palsies.
