Objective To compare the outcomes between bilateral lateral rectus recession (BLR) and
unilateral recession resection (R&R) procedures in the treatment of basic intermittent
exotropia. Methods Databases from Medline, Embase, Web of Science and the Cochrane
Register of Controlled Trials were searched prior to June 2, 2017. From these searches,
three eligible randomized studies and three retrospective cohort trials, which compared
conventional BLR versus R&R procedure were identified. Differences observed between …

In his classic classification of exotropia (XT), Burian 1 categorized patients according to their
distance/near difference. For lack of a better term, he labeled patients in whom the distance
XT approximately equaled the near deviation as having a “basic” pattern, because they had
neither a divergence excess nor a convergence insufficiency pattern. More recently, Burian's
basic XT has been renamed as being an “XT that lacks tenacious proximal fusion (TPF),” a
term that has subsequently been updated to simply “lacking the Scobee Phenomenon.” 2, 3 …
