“…On the other hand, neurotypical children with IIN have been reported to have WTR astigmatism throughout their childhood. 23 , 34 Our analysis showed that nystagmus had no effect on the prevalence or type of astigmatism in children with DS.…”

Purpose Children with Down's syndrome (DS) are known to have poorer visual acuity than neurotypical children. One report has shown that children with DS and nystagmus also have poor acuity when compared to typical children with nystagmus. What has not been established is the extent of any acuity deficit due to nystagmus and whether nystagmus affects refractive error within a population with DS. Methods Clinical records from the Cardiff University Down's Syndrome Vision Research Unit were examined retrospectively. Binocular visual acuity and refraction data were available for 50 children who had DS and nystagmus and 176 children who had DS but no nystagmus. Data were compared between the two groups and with published data for neurotypical children with nystagmus. Results The study confirms the deficit in acuity in DS, compared to neurotypical children, of approximately 0.2 logMAR and shows a deficit attributable to nystagmus of a further 0.2 logMAR beyond the first year of life. Children with both DS and nystagmus clearly have a significant additional impairment. Children with DS have a wide range of refractive errors, but nystagmus increases the likelihood of myopia. Prevalence and axis direction of astigmatism, on the other hand, appear unaffected by nystagmus. Conclusions Nystagmus confers an additional visual impairment on children with DS and must be recognized as such by families and educators. Children with both DS and nystagmus clearly need targeted support.

“…As for the astigmatic component, Australian low vision data further presented a high prevalence in the subgroup of idiopathic nystagmus (46). Indian childhood data likewise reported astigmatism as prevalent, but did not specify the spherical refractive distribution (47). Meridional aspects of astigmatism compared to nystagmus type has further been discussed, in particular when horizontal (43, 44, 46, 48, 49).…”

“…The prevalence of ametropia is much higher in patients with nystagmus than in the general population [ 12 ]. Almost half of the children with congenital nystagmus also have astigmatism, which may not be present at birth, but may appear during the first decade of life [ 13 ]. Our group analyzed the refractive error in 81 children with nystagmus (data not published) and found myopic astigmatism to be the most prevalent type (43% of eyes).…”

Abnormal Head Position in Infantile Nystagmus Syndrome

et al. 2011

View full text Add to dashboard Cite

Infantile nystagmus is an involuntary, bilateral, conjugate, and rhythmic oscillation of the eyes which is present at birth or develops within the first 6 months of life. It may be pendular or jerk-like and, its intensity usually increases in lateral gaze, decreasing with convergence. Up to 64% of all patients with nystagmus also present strabismus, and even more patients have an abnormal head position. The abnormal head positions are more often horizontal, but they may also be vertical or take the form of a tilt, even though the nystagmus itself is horizontal. The aim of this article is to review available information about the origin and treatment of the abnormal head position associated to nystagmus, and to describe our treatment strategies.
