Percentages of patients with fusion and stereo perception in the two treatment groups. Fusion was acceptable when detected by both the Worth 4 dot at near and the Bagolini lenses. The upper values in the stereopsis bars correspond to the percentages obtained with the Randot circles (at least 400 seconds of arc) and the lower values to those with the TNO test (at least 480 seconds of arc). The difference is not significant in the fusion (p=0.71) and in the stereo perception percentages as measured by the Randot circles (p=0.70) and TNO (p=0.90).
