Neurological exotropia: do we need to decrease surgical dosing?

Surgical responses and outcomes of bilateral lateral rectus recession in exotropia with cerebral palsy

“…Although the proportions of undercorrection and overcorrection were not disclosed, they reported that the rate of overcorrection was about half as common as esotropes with CP after bilateral MR recession, which is consistent with our findings (Ma et al 2013). Bang & Brodsky (2013) reported the 2-month result of BLR recession in nine exotropes with various neurological diseases. The authors assumed that the increased dose-response curve resulted from the secondary contracture of the lateral recti and thus reduced the surgical dosage by 1 mm per eye from the Parks' surgical table (Mitchell & Parks 2000) for intermediate exodeviations .…”

“…However, there are only few previous studies reporting the outcome of strabismus surgery in exotropes with CP (Hiles ; Ghasia et al. ; Bang & Brodsky ; Han et al. ).…”

“…Exotropia is far more common in the Asian population, even in patients with CP (Jenkins 1992;Katoch et al 2007;Woo et al 2011). However, there are only few previous studies reporting the outcome of strabismus surgery in exotropes with CP (Hiles 1975;Ghasia et al 2011;Bang & Brodsky 2013;Han et al 2015).…”
