“…Consequently, functional deficits have been described in albinos, both in humans and in animals, such as cats and ferrets [1,16,18]. Of particular interest here is that pigmented rats have a better visual acuity, spatial contrast sensitivity and spatial learning than albino rats [5,24,43].…”

“…The 3 main variables of the period of foveation are: duration, 14−16 accuracy of foveation, 12,17,18 and velocity during foveation. 19 A number of acuity functions have been developed using these variables: the Nystagmus Foveation Function, 18 the Nystagmus Acuity Function, 20 the Nystagmus Acuity Function for Position only, 20 the Nystagmus Acuity Estimator Function, 21 The object of this paper is to assess whether there are any nystagmus waveform variables or functions that predict visual acuity in adults, which may subsequently be applied to young children.…”

In preverbal children, it is difficult to assess visual acuity accurately. If nystagmus waveforms can be used to predict visual acuity in these young patients, then they would be a useful additional clinical tool. Existing acuity predictors were assessed in 10 adults with idiopathic early onset nystagmus. The most reliable predictor in this group of patients was mean velocity of the waveform. The mean velocity of the waveform may be used in preverbal children to give an estimate of best potential visual acuity in adulthood, and estimated best potential visual acuity at the current age.

“…Therefore, it is imperative that they be afforded the best possible retinal image, regardless of whether they have a concomitant sensory abnormality. Indeed, even patients with ocular albinism may achieve visual acuities of 6/12, 7,64 although this is not the rule.…”

Infantile nystagmus: current concepts in diagnosis and management

This review examines current approaches to the diagnosis and management of congenital forms of nystagmus. Emphasis is placed on diagnostic features that are amenable to clinical identification but those issues that can be addressed only with more detailed investigations, such as eye movement recording, are indicated. Non-surgical management, including prism spectacles, contact lenses and vision therapy, is discussed, as are surgical approaches. Because many aspects of congenital forms of nystagmus, particularly as experienced by patients with the condition in their normal lives, are poorly addressed in both the clinical and research literature, these limitations are also highlighted.
