Stereoacuity Outcomes During One Year Of Spectacle Wear in Patients Aged 3-<10 Years with Previously Untreated Bilateral Refractive Amblyopia (N=113)

Change in Stereoacuity From Baseline to One Year, levels^*
Mean (SD)	1.9 (2.1)
Range	-4.0 to 6.0

Stereoacuity at One Year, in seconds of arc^†	N (%)
40	13 (13)
60	12 (12)
100	18 (19)
200	11 (11)
400	17 (18)
800	3 (3)
>800	23 (24)

Negative values represent decrease in stereoacuity. Change in steroacuity could not be calculated for 19 patients: 5 were unable to perform testing (3 at baseline and 2 at one year) and 14 did not have testing completed at one year.

^†

16 children were missing stereoacuity outcomes at one year: 2 children were unable to perform testing and 14 did not have testing completed.
