Abstract
Purpose

To describe the long-term surgical outcomes of bilateral lateral rectus recession in patients with intermittent exotropia.

Methods

Retrospective review of 18 patients diagnosed with intermittent exotropia between 1995 and 2005 who underwent surgical treatment in the Ramon y Cajal Hospital.

Results

Of the 18 patients with intermittent exotropia, 50% were basic subtype. All of them underwent bilateral lateral rectus recession, associated with a previous failed botulinum toxin injection in 8 of them. Satisfactory results (less than 10 PD orthophoria) were obtained in 68.2% of the patients after a 4.5-year follow-up period.

Conclusions

Bilateral lateral rectus recession is an effective and stable surgical procedure in the long-term motor control of intermittent exotropia, especially in basic subtype. Previous injection of botulinum toxin did not affect the results.

Resumen
Propósito

Evaluar los resultados a largo plazo de la cirugía de retroinserción bilateral de los rectos laterales para la corrección del estrabismo divergente intermitente.

Método

Estudio retrospectivo de 18 pacientes diagnosticados de estrabismo divergente intermitente (EDI) entre los años 1995 y 2005 que precisaron tratamiento quirúrgico en el Hospital Ramón y Cajal de Madrid.

Resultados

De los 18 pacientes con exotropía intermitente, un 50% fueron de tipo básico. Todos ellos fueron intervenidos mediante retroinserción bilateral de los rectos laterales asociado con inyección de toxina botulínica previa en ocho. Se obtuvieron resultados satisfactorios (ortoforia menor de 10DP) en un 68,2% de los pacientes tras un periodo de seguimiento medio de 4,5 años.

Conclusiones

La retroinserción bilateral de los músculos rectos laterales es una técnica efectiva y estable en el control a largo plazo de la desviación motora en el estrabismo divergente intermitente, especialmente en el subtipo básico. La inyección previa de toxina botulínica no cambió este resultado.
