Botulinum alignment for congenital esotropia.
This is the first report of a group of patients with congenital esotropia examined for motor and sensory evidence of binocularity a minimum of 3 years after alignment by botulinum. Evidence for binocularity was clearly present in approximately one half of the patients. Lag time to satisfactory alignment was at least 1 month (average, 5 months) following the initial botulinum injection. The results must be considered preliminary. However, when these results are compared with those of patients with congenital esotropia aligned by incisional surgery by age 2 years and examined with the same testing devices by this same investigator, botulinum alignment appears to be less effective than surgical alignment in establishing evidence for binocularity (P < 0.005).
