Sensorial Retinal Relationship in Concomitant Strabismus

Outcomes of Hyperopic LASIK With the NIDEK NAVEX Platform Centered on the Visual Axis or Line of Sight

“…The mean total offset in the hyperopic population was as high as 0.50 mm (data not shown). Based on these and other documented differences,7 centering on the LOS for hyperopic ablations may risk symptoms associated with decentered ablations likely inducing coma. Due to the ambiguous position of LOS under different illumination, which cannot be addressed properly during surgery, we believe centering on the LOS poses greater risk of decentered ablations 2,12.…”

Single vision during ocular deviation in intermittent exotropia

“…Their unusual visual experience is reflected in special cortical mechanisms which achieve single vision despite the deviation. Two different basic forms of these anti‐diplopic mechanisms have been recognized in the literature: anomalous retinal correspondence () 21,22 ; and suppression. 17,23 Although both these proposed mechanisms avoid double vision, they do so in quite different ways.…”

“…Instead, the two images compete for perceptual dominance, with each image being alternately perceived and suppressed from consciousness. There is currently no consensus regarding whether strabismic suppression and normal binocular rivalry suppression are mediated by the same underlying neural mechanisms 21,51–55 or not 42,56–58 . For example, Leonards and Sireteanu 59 showed that the time courses of suppression for amblyopes and normal observers were similar when balancing the two eyes in amblyopes.…”

“…For example, if it is always the right eye which exodeviates, we might predict that it would always be this eye which is suppressed in order to avoid diplopia, whereas if both eyes deviate alternately, one would expect both to be suppressed in turn. Intermittent exotropia has been subdivided into classes by Burian, 21 but we are not aware of any studies examining how these relate to different forms of suppression. It has been suggested that anomalous retinal correspondence may be more likely to arise when the angle of deviation is small, but this also has not been rigorously tested, nor is it known what may cause a small constant strabismus with anomalous retinal correspondence gradually to decompensate into a larger strabismus with suppression.…”
