Infantile nystagmus syndrome (INS) is a constant involuntary oscillation of the eyes which, in 80% of cases, is associated with a sensory defect such as albinism.
The onset of INS is generally at birth or in the first few postnatal weeks, although nystagmus can also onset in later life, associated with brain lesions.
This article concentrates on INS and how visual potential is maximised by the use of foveation periods, null position and head nodding. It also looks at how nystagmus impacts vision, including its effect on visual acuity, contrast sensitivity and refractive error.
