Abstract
Purpose::
A number of patients with congenital esotropia, whose proportion is not currently known, present with associated Distance/Near Incomitance (DNI). In addition a further proportion develop an Accommodative Component (AC) to their strabismus with the passage of time, which at times may lead to the recurrence of esotropia. The object of this study was to evaluate the incidence of DNI and of an accommodative component in patients treated using botulinum Toxin A (BT),in order to assess the value of this form of management in the diagnosis of both DNI and AC in congenital esotropia and the improvement of subsequent surgical planning where it proves necessary.
Methods::
Retrospective study of the clinical histories were studied of 26 patients with congenital esotropia who were treated by means of botulinum toxin.
Results::
42% of the patients controlled their deviation by the botulin toxin inyections.The annual risk of developing DNI and AC in our sample was 7.9% and 18%.
Conclusions::
Botulinum toxin is a good diagnostic method for both of these since it provides an early intervention that may unmask them (as well as correctly align many patients) and thus subsequent surgery can be successfully individualized.
