• In complete abducens nerve palsy, there is no function in the lateral rectus, and the eye cannot abduct beyond the midline.
• During the acute phase, classification of partial versus complete palsy is primarily based on whether abduction can pass the midline.
• Early botulinum toxin injection into the ipsilateral medial rectus (within 1–3 months) may be considered in complete or bilateral abducens nerve palsies, in which spontaneous recovery rates are relatively low.
• The first priority is always to treat the underlying causes.
• During the acute phase, patching, opaque lenses, or prisms are recommended to relieve diplopia.
• By inducing temporary chemodenervation of the ipsilateral medial rectus, it improves agonist-antagonist balance, reduces esotropia, enhances binocularity, and prevents contracture.
• Early injection may improve binocular function more quickly, thereby alleviating diplopia while awaiting recovery or surgery.
