Table 1 Baseline patient characteristics

	IXT (n = 17)	Controls (n = 15)	p
Mean age ± SD (range), yrs	10.0 ± 4.09 (5 to 20)	9.1 ± 2.58 (6 to 14)	0.711^*
Female sex, no. (%)	8 (53.1)	8 (46.9)	0.723^**
Mean refractive error ± SD (range), D
Fixating eye	−0.74^a ± 1.42 (−4.75 to 1.00)	−1.27^a ± 2.07 (−5.25 to 0.88)	0.551^*
Deviating eye	−0.60^a ± 1.44 (−4.88 to 1.13)	−0.92^a ± 1.88 (−5.75 to 0.75)	0.852^*
Mean angle of deviation ± SD (range), PD
Distance	20.2 ± 7.19 (12 to 35)	-	-

Refractive error is presented as spherical equivalent. Fixating and deviating eyes in patient with IXT were compared to right and left eyes in controls, respectively
IXT intermittent exotropia, SD standard deviation, D diopters, PD prism diopters
^* Mann–Whitney test, ^** Chi-square test
^a Negative values refer to myopic refractive error
