Abstract

Introduction: Variations in sterioacuity may be used in an assessment of intermittent exotropia. Intermittent exotropia is divergent squint of eyes that is worsened due to daily visual tasks and its resultant tiredness therefore the amount of deviation increases. The purpose of this study is to determine the effect of daily work and resultant tiredness on near sterioacuity among intermittent exotropic patients. Methods: In this cross-sectional study, 600 dormitory students of Mashad University of Medical Sciences, ranging in age from 21 to 23 years, examined with alternate cover test to diagnose intermittent exotropic cases. 30 students had intermittent exotropia and along with 15 normal cases constituted the case-control group. Sterioacuity was measured twice, in the morning and at night, with Randot-SO 001 test. Suppression was checked with Bagoloni striate lens and 4 prism diopter base out test. Data were statistically analyzed with SPSS software (version 13). Results: The measured deviation in intermittent exotropic cases showed a significant difference between the deviation in the morning and late at night among 23.33 (7 cases) (P=0.00). In addition, sterioacuity decreased significantly at night, (P=0.00) among these cases. Despite the increase in the deviation among 53.3 (16 cases) at night, steriacuity was not changed significantly. 23.33 (7 cases) did not show any changes in the morning and at night, both in deviation amount and sterioacuity measurement. Conclusion: In most intermittent exotropic cases, there is no significant correlation between intermittent exotropia and near sterioacuity variations after daily work and resultant tiredness (P<0.696).
