Quality of life and visual function in Nigeria: findings from the National Survey of Blindness and Visual Impairment [PDF]

, 2011
Aims To assess associations of visual function (VF) and quality of life (QOL) by visual acuity (VA), causes of blindness and types of cataract procedures in Nigeria. Methods Multi-stage stratified cluster random sampling was used to identify a nationally

Contextual modulation of primary visual cortex by auditory signals [PDF]

, 2017
Early visual cortex receives non-feedforward input from lateral and top-down connections (Muckli & Petro 2013 Curr. Opin. Neurobiol. 23, 195–201. (doi:10.1016/j.conb.2013.01.020)), including long-range projections from auditory areas.

Variants in NR6A1 cause a novel oculo vertebral renal syndrome

Nature Communications
Colobomatous microphthalmia is a potentially blinding congenital ocular malformation that can present either in isolation or together with other syndromic features. Despite a strong genetic component to disease, many cases lack a molecular diagnosis.

Functional Visual Acuity

Investigative Opthalmology & Visual Science, 2018
Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function.

The c.119-123dup5bp mutation in human γC-crystallin destabilizes the protein and activates the unfolded protein response to cause highly variable cataracts

Scientific Reports
Ordered cellular architecture and high concentrations of stable crystallins are required for the lens to maintain transparency. Here we investigate the molecular mechanism of cataractogenesis of the CRYGC c.119-123dupGCGGC (p.Cys42AlafsX63) (CRYGC5bpdup)
