ABSTRACT

Objective: The present study was performed to evaluate the surgical results of lateral rectus recession in subjects with exotropia of 40 PD or less. Method: A longitudinal, descriptive, observational and comparative study was realized in patients with exotropia of 40 PD diopters or less of any etiology. The participants had an equatorial or retroecuatorial lateral rectus recession according to the magnitude of deviation. Two groups were formed, one with patients with intermittent exotropia and the other with non-intermittent exotropia. The statistic analysis was made by the exact Fisher’s test. For the first group orthophoria or a deviation less than or equal to 10 PD of exoforia-tropia was considered a good result. For the second group an exo or esodeviation up to 10 PD. Results: 28 patients were studied; 11 were males and 17 females, the mean age raised from 2 to 39 years old. The presurgical deviation magnitude was between 14 to 40 PD with a mean of 25.07 PD. A good result was determined in 93.7% of those participants who had intermittent exotropia and 66.7% in non-intermittent exotropia. The statistic data showed p= 0.03 between groups. Conclusions: Lateral rectus recession for exotropia is an effective surgical method for correcting small to moderate deviations, especially if any possibility of fusion exists.
