Although there are many confusing case reports on unusual ocular-motor cases of nerve palsy, there is literature to illuminate this topic. A good evaluation usually gives the ophthalmologist an idea about the etiology. This review covers some important findings regarding this group of diseases. Results of superior oblique myokymia show that this disease is probably related to fourth-nerve palsy and its improvement stage. There also have been some new reports on pseudomyasthenia gravis. The debate on the central or peripheral origin of sensory involvement in myotonic dystrophia continues, although there seems to be more evidence on the central origin of the ocular findings.
