Abstract

PURPOSE
This study was designed to determine which sensory test best reflects the improvement of binocular function according to the surgical outcome of intermittent exotropia METHODS: We examined the visual acuity, refractive error, angle of exodeviation, fusional status with the Worth-4-dot, Bagolini tests and stereoacuity with the Titmus test preoperatively in 61 intermittent exodeviation patients who had undergone the bilateral lateral rectus recession operation from February 2002 to 2003 July. We compared the binocularity tests between the two groups: esodeviated and orthotropic or exodeviated. RESULTS: The average improvement time of the Bagolini, Worth 4 dot and Titmus tests was 0.54 +/- 1.2, 2.03 +/- 2.90, 1.12 +/- 2.1 weeks, respectively. Although the shortest time was for the Bagolini test (p=0.001), the Titmus test was more sensitive. CONCLUSIONS: The high variability of the binocularity tests should be remembered and take into account when we interpret the test results.
