The Relationship Between Bagolini Test and Other Sensory Tests and Surgical Outcome of Intermittent Exotropia

Purpose: To determine the surgical outcome of intermittent exotropia according to preoperative retinal correspondence with the Bagolini striated glasses test and the relationships between the Worth-4-dot test or stereoacuity with the B-VAT test. Methods: We analyzed retrospectively preoperative fusion statuses with the Worth-4-dot test, stereoacuity with the B-VAT test and retinal correspondence with the Bagolini striated glasses test to determine any possible relationships with surgical outcome. The surgical outcome and binocular function were further investigated six months postoperatively in 114 patients who had undergone surgery for intermittent exotropia. Results: The surgical outcome according to preoperative fusion status and stereoacuity was not statistically significant(p=0.38, p=0.59). whereas, preoperative retinal correspondence with the Bagolini striated glasses test was statistically significant(p<0.01). More over there was a relationship between retinal correspondence and fusion status or stereoacuity(p<0.01, p<0.01). Conclusions: The preoperative Bagolini striated glasses test was the factor predicting a favorable surgical outcome and there was a relationship between the preoperative Worth-4-dot test and the B-VAT test.
