Visual Image Quality Reduced in Down Syndrome
Individuals with Down syndrome show reduced visual acuity and visual image quality compared with individuals without Down syndrome.
Even with optimized spectacle correction, both visual acuity and visual image quality are reduced in those with Down syndrome, according to a study in the journal Optometry & Vision Science.
A sensory deficit in the visual system may be part of the reason, along with uncorrected aberrations. Differences are seen in both retinal thickness and dendritic spines in patients with Down syndrome.
The team enrolled 30 adult patients with Down syndrome (average age, 29±10 years) to understand if an association exists between a reduction in visual acuity and visual image quality.
A sensory deficit in the visual system, in either the eye or retina or at the cortical level may be part of the reason along with uncorrected aberrations.
Author's summary: Down syndrome affects visual image quality.
