RESUMO

According to controversial results between migraine headaches and binocular vision anomalies, this study was designed to investigate the relationship between some parameters of binocular vision refractive errors and migraine headache. In this case-control study, 30 patients with neurologically diagnosed migraine who had inclusion criteria were selected as case group and 30 persons with no migraine headache were selected as control group. First, patients were screened by standard headache questionnaire and diagnosis refined by neurologist. The Refractive errors were determined by retinoscopy and were corrected. Then near point of convergence, jump convergence, stereopsis, fusional reserves and far and near deviation were determined. Data were analyzed by SPSS.15 software, using Man-Withney U test and multiple logistic regressions. The mean of near phoria, stereopsis, far positive fusional reserve, far negative fusional reserve, near positive fusional reserve, near negative fusional reserve in case and control groups were 6.5 +/- 2.85, 8.3 +/- 6.72 pd, 49.0 +/- 26.11, 154.17 +/- 333.82 sec/arc, 10.7 +/- 2.76, 6.07 +/- 5.07, 18.2 +/- 4.7, 11.0 +/- 7.37, 16.5 +/- 4.49, 13.97 +/- 8.72, 22.7 +/- 5.22 and 14.67 +/- 9.25 pd, respectively. The means of above parameters and jump convergence was significantly different between two groups [P<0.05]. However; no significant difference was observed between two groups for other variables [P>0.05]. In multiple logistic regression only jump convergence, far positive fusional reserve and near positive fusional reserve stayed in model [P<0.05]. This study showed higher rates of binocular vision anomalies [abnormal jump convergence, higher amounts of near deviation, abnormal positive and negative fusional convergence and reduced stereopsis] in migraine group than control. Hence, people who experience migraine headaches should be referred to their optometrist regularly to evaluate their binocular vision statuses
