Relationship among Dominant Eye & Hand and Deviated Eye under General Anesthesia

Purpose: To evaluate the association between ocular dominance, hand dominance and eye deviation in orthophoric and strabismus patients under general anesthesia during surgery. Methods: The subjects were divided into 2 groups. Group 1 was composed of 38 patients who underwent strabismus surgery and group 2 was composed of 107 patients who underwent non-strabismus surgery under general anesthesia. Best corrected visual acuity (BCVA), dominant hand and fixating eye were obtained before surgery, and ocular dominance was assessed using the hole-in-the-card test. Under general anesthesia, we took a digital photo of both eyes, and the deviating eye was determined. Results: Under general anesthesia, the deviated eye showed no statistically significant correlation to the dominant eye and dominant hand in group I, respectively (<EM>p </EM>= 0.61, 0.74, respectively). In group II, there was no correlation between the deviated eye and the dominant eye (<EM>p </EM>= 0.65). The deviated eye also showed no correlation to the dominant hand in group II (<EM>p </EM>= 0.61). Conclusions: There was no correlation between the dominant and deviated eye under general anesthesia in the strabismus surgery group and the non-strabismus surgery group. Also, there was no correlation between the dominant hand and the deviated eye in patients under general anesthesia in the 2 groups. J Korean Ophthalmol Soc 2014;55(10):1530-1534
