ABSTRACT

ABSTRACT: The toxin clinic database was reviewed, identifying patients with strabismus secondary to permanent or temporary impairment of vision. Five hundred and three patients fulfilled our criteria. There were 301 males and 202 females, with a mean age at treatment of 35 years. Three hundred and eighty three patients (76%) had exotropia, 114 (22.5%) had esotropia and 6 (1.5%) had vertical strabismus. Reduced vision secondary to trauma accounted for 45% (227) of patients. Other causes were congenital anomalies 121 (24%), refractive error 30 (6%), retinal detachment 20 (4%), senile cataract 24 (5%), corneal problems 19 (4%), glaucoma 10 (2%) and 52 (10%). Ninety nine (20%) patients were managed with continued toxin treatment. Two hundred and eighteen patients (43%) proceeded to surgery. Forty patients (8%) required no further treatment as they regained binocularity by injection alone.
