Table 3.

Changes in stereopsis between True CI and Masked CI groups at 3 years after slanted lateral rectus recession.

	Improved	No Change	Decreased	p-value*
True CI group	17 (48.6%)	18 (51.4%)	0 (0%)	0.073
Masked CI group	10 (50%)	9 (45%)	1 (5%)

CI  = convergence insufficiency; Masked CI group = near-distance differences of <10 PD before diagnostic occlusion and ≥10 PD after diagnostic occlusion; True CI group = near-distance difference ≥10 PD before and after diagnostic occlusion;

*P value calculated using Fisher’s exact test between True CI and Masked CI groups.
