The use of voriconazole in the treatment of Aspergillus fumigatus keratitis

Botulinum toxin for the treatment of acute-onset concomitant esotropia in Chiari I malformation Acute-onset esotropia (ET) is a rare presentation of Chiari I malformation. The ET may resolve following neurosurgical decompression, although this is not usually immediate. 1 Where neurosur- gery is not undertaken, Kowal et al 2 suggest prismatic correction or strabismus surgery. The latter may result in temporary correction of the strabismus, as the strabismus can recur and resolves only following decompression. 3 Botulinum toxin (BT) has been reported as successful in one case where the ET did not resolve following neurosurgery. 4 Despite BT being a common treatment for acute acquired concomitant ET, 5 no previous case has been reported in which BT was used prior to neurosurgical decompression for Chiari I malformation.
