Cryptogenic unilateral paralysis of the superior oblique muscle
J. M. Coppeto and S. Lessell
Fifteen patients spontaneously developed paralysis of one superior oblique
muscle, which remained unexplained after an initial evaluation. Follow-up
evaluation showed that all of the patients' conditions were improved.
Twelve of the patients had enjoyed spontaneous, functional recoveries
within four months. Three had residual diplopia that was relieved by
prisms. No patient subsequently developed evidence of any local or systemic
disease that could explain the ophthalmoplegia. One patient suffered a
recurrence 3 1/2 years after his first episode that lasted three months and
spontaneously cleared.
