• If acute onset of esotropia is comitant, its cause is generally believed to be benign. Although this is, by and large, true, it is now clear that acute comitant esotropia may be associated infrequently with central nervous system illness. We describe six children who presented with acute onset of comitant esotropia, and who were found to have tumors of the brain stem or cerebellum. Four of the patients underwent strabismus surgery after appropriate neurologic and neurosurgical treatment was completed. In none of these patients was ocular motor fusion reestablished.
