[Results of suture fixation in esotropia with non-accommodative far-near uncomitance]
1Service d'Ophtalmologie de la Faculté de Médecine de Cerrahpasa, Université d'Istanbul.
Purpose:
In esotropia, the dynamic component is the unique objective of suture fixation. The aim of this study was to assess outcome after the suture fixation used with or without other conventional methods and to determine the value of the anesthesia sign for evaluating the innervational factor of these esotropias.
Methods:
Unilateral and bilateral posterior fixation sutures were applied in 54 cases exhibiting far-near incomitance between 10-20. The same procedure was applied in 14 cases with similar type of esotropia with incomitance greater than 20.
Results:
A 100% success rate was achieved when suture fixation was used alone. When suture fixation was applied in combination with other conventional methods for cases with a static and a dynamic component the success rate was 86% (37/43 cases) in unilateral myopexy and 92% (12/13 cases) in bilateral myopexy.
Discussion:
In cases with this type of esotropia, suture fixation, the only means of correcting a dynamic angle, gives good results as the component disclosing the apparent angle is well-documented. In addition, these findings emphasize the value of the general anesthesia sign to determine the innervational factor causing the dynamic angle.
