^aPatient 2B is the same patient as 2A who had subsequent bimedial recession with Tutopatch due to a residual angle of 14 PD; ^bOU = both eyes; ^cOD = right eye; ^dOS = left eye; ^eSOR = superior oblique recession to the nasal side of the superior rectus 4 mm distal to its insertion; ^fMRR = medial rectus recession; ^gIOR = inferior oblique recession; ^hSRR = superior rectus recession; ⁱIRR = inferior rectus recession.
