Botulinum toxin injection for postoperative diplopia testing in adult strabismus

Usefulness of Botulinum Toxin Type-A in the Treatment of Chronic Sixth Nerve Palsy

“…In other strabismus, as congenital esotropia or horizontal strabismus in adults, Botulinum toxin is definitely an inferior surgical treatment of the ocular muscles [2]. Moreover the use of botulinum toxin type A is efficient in the identification of adult patients with constant strabismus who are at high risk o developing intractable diplopia after surgery [15]. The majority of studies identify the Botulinum toxin A injection into extra-ocular muscles the ideal therapy for the treatment of sixth cranial nerve palsy [1], on 36.8% of the patients with a final ocular alignment within 10 prism dioptres of orthotropia and achieved fusion and primary gaze position.…”

Binocular Function

“…Using botulinum toxin gives the patient a more realistic period in which to adapt and aid the decision (Khan et al 2008). Using botulinum toxin gives the patient a more realistic period in which to adapt and aid the decision (Khan et al 2008).…”

Surgical Management

“…Botulinum toxin can also be used to temporarily correct the strabismus and provide additional information about postoperative diplopia risk and its likely tolerance (Ketley et al 1987;Khan et al 2008). The patient is asked to view a fixation target appropriate to his or her level of acuity at near and distance through prisms and asked what is observed and the purpose of the test explained.…”
