Visual perception in infantile nystagmus

A clinical perspective on recent developments in the field of Infantile nystagmus (IN).

Share options


Infantile nystagmus (IN) is often found in conjunction with afferent visual system pathology, but even in isolated cases, visual acuity (VA) is usually reduced. Most individuals with IN do not experience oscillopsia (illusory motion of the world). The presence of visual stability, despite constant eye motion, provides a uniquely dynamic perceptual scenario. Recent advances have demonstrated that VA alone is insufficient to explain fully the subjective perceptual experience of IN. The purpose of this review is to provide a clinical perspective on recent developments in the field, and summarise the novel techniques being used to gain a better understanding of the impact of treatment on visual function in IN.
