Article title: Forty-five Years of Studying Intermittent Exotropia — What Have I Learned? The WSPOS Keynote Strabismus Lecture, October 3, 2020

Authors: Burton J. Kushner

Journal: Journal of Binocular Vision and Ocular Motility

When the above article originally published online, an incorrect symbol appeared in Table 2, column 1, row 3. Distance XT > Near XT'^b should be Distance XT = Near XT'^b.

The correct table is as follows:

Table 2. Kushner’s vs Burian’s Classification of IXT.

Initial Presentation	Augmented Near Measurement^a	Burian’s Classification	Kushner’s Classification	Kushner’s Treatment Recommendation
Distance XT > Near XT’^b	Prolonged Monocular Occlusion XT still > XT’	Divergence Excess	XT with Probable Convergence Excess (not Accommodative)	LROU Rec or Possibly R&R^d, Surgeon’s choice
	Prolonged Monocular Occlusion XT = XT’	Simulated Divergence Excess	XT with ScPh	LROU Rec or R&6R, Surgeon’s choice
	+3D at Near XT still > XT’	Divergence Excess	XT with Probable Convergence Excess (not Accommodative)	LROU Rec or R&R, Surgeon’s choice
	+3D at Near XT = XT’	Simulated Divergence Excess	Pseudo High AC/A or True High AC/A (needs more testing)	If Pseudo High AC/A, LROU Rec or R&R, Surgeon’s Choice. If True High AC/A, Overminus and Bifocal
Distance XT = Near XT’^b	N/A	Basic	XT without ScPh	R&R or LROU rec With Enhanced Formula
Near XT ‘> Distance	Prolonged Monocular Occlusion Distance XT Unchanged	Convergence Insufficiency^c	Convergence Insufficiency	LROU Rec, MROU Res, or R&R, all targeting Distance angle with Offset to Induce V Pattern
XT^b	Prolonged Monocular Occlusion Distance XT Increases	Convergence Insufficiency^d	Pseudo Convergence Insufficiency	LROU Rec, MROU Res, or R&R, Surgeon’s choice

^aAugmented either with prolonged monocular occlusion or +3D lenses

^bWith threshold of ≥ 10∆

^cBurian did not do prolonged monocular occlusion on convergence insufficiency so diagnosis would not be changed.

^dR&R for this classification not supported by data but would be consistent with this understanding of selective surgery for distance-near differences.

LROU = lateral rectus muscles bilaterally, MROU = medial rectus muscle bilaterally, Rec = recession, Res = resection, R&R = Recess/Resect Procedure, ScPh = Scobee Phenomenon, N/A = not applicable. Prime (‘) denotes near measurement.

This has been corrected in the article.
