This thesis investigates the relationship among personality (extroversion), physical characteristics (interpupillary distance and zygomatic arch distance), and the degree of deviation of lateral heterophoria. The Eysenck Personality Inventory was the protocol for personality, the flash-modified Thorington and Von Graefe tests for lateral heterophoria deviation, and the millimeter rule and Essel monocular interpupillary distance tests for physical characteristics. A negative correlation was found between the personality trait and the physical characteristics. No statistically significant correlation was found between the personality trait and the degree of deviation of lateral heterophoria. Interpupillary distance and phoria were significantly correlated in a positive fashion, while the correlation between zygomatic arch distance and phoria was not statistically significant.
