Recent understanding of binocular vision in the natural environment with clinical implications
2022, Progress in Retinal and Eye ResearchCitation Excerpt :Intriguingly, the potential for stable percepts remains in early onset cases. These patients are capable of perceptual adaptation despite dramatic retinal image motion resulting from eye movements that are quite visible to another observer (Goldstein et al., 1992; Bedell 2000). This perceptual stability is attributed to the subtraction of eye movement signals from the incoming visual information, the corollary discharge or efference copy discussed above.
Nystagmus in childhood
2014, Pediatrics and NeonatologyCitation Excerpt :The first is the “sampling theory”, by which the information from the most stable retinal images during the foveation periods can be used to establish a stable image, whereas the rest of the nystagmus cycle is ignored.12 The second hypothesis is the “remapping theory” whereby an efference copy signal of the nystagmus waveform is used to cancel the effects of motion.13 This is probably the most likely theory because vision during the fast phases of the nystagmus cycle has been documented which argues against sampling.
Nystagmus and saccadic intrusions
2011, Handbook of Clinical NeurologyCitation Excerpt :In pendular waveforms, the oscillation is “flattened” by a foveation period when the eye is closest to the target (see Fig. 13.18A). Foveation periods are one important reason why many patients with INS have near-normal vision (Sheth et al., 1995; Chung and Bedell, 1997), and why most do not complain of oscillopsia, despite continuous movement of their eyes otherwise (Goldstein et al., 1992; Dell'Osso et al., 1997; Abadi et al., 1999; Ukwade and Bedell, 1999). Foveation periods are not an invariable finding in INS, however, and when they are absent or poorly developed, visual acuity is usually impaired (Dell'Osso and Leigh, 1992; Bedell and Bollenbacher, 1996).
