“…Based on reports from other studies conducted in Britain, the leading causes of serious visual loss in children are congenital cataract, cortical visual impairment, optic atrophy, disorders of the retina, and congenital ocular anomalies. [56][57][58] In Hungary, a population based study was carried out to examine all registered visually impaired children aged 6-14 years. The principal causes of severe visual impairment in children were congenital cataract (17%), congenital eye abnormalities (15%), high myopia (13%), retinopathy of prematurity (11%), retinal degenerations (10%), congenital anomalies (10%), nystagmus (9%), and optic atrophy (7%).…”

“…Visual impairment early in life has profound implications in terms of reduced educational, recreational and social experience in children 1 2. Even though childhood visual impairment is less common than in adults, the associated life-long burden of disability is more significant in terms of number of ‘blind years’ experienced by children in their life time 3.…”

Methods: A list of 121 items was generated from 13 focus groups with 4 children and young people with and without a visual impairment. A long 89 5 item questionnaire was piloted with 45 visually impaired children and young 6 people using face to face interviews. Rasch analysis was used to analyze the 7 response category function and to facilitate item removal ensuring a valid 8 unidimensional scale. The validity and reliability of the short questionnaire 9were assessed on a group of 109 visually impaired children (58.7% boys; 10 median age, 13 years) using Rasch analysis and intraclass correlation 11 coefficient (ICC).

“…From a global perspective, this condition is also one of the leading causes of childhood blindness (Rahi & Gilbert 2005). However, also among those who survive without severe ROP, several studies show that the frequency of other and less severe, long-term ocular and visual complications is increased (Fledelius 1996a,b,c;Darlow et al 1997;Larsson et al 2003Larsson et al , 2005Cooke et al 2004;Holmstro¨m & Larsson 2008;Lindqvist et al 2007Lindqvist et al , 2008Hellgren et al 2007).…”

ABSTRACT.Purpose: Progress in neonatal care has caused an increased survival of children born extremely preterm. The aims of this study were to examine the long-term visual function and ocular development in an unselected cohort of extremely preterm infants and relate the results to neonatal morbidity and long-term neurodevelopmental outcome. Methods: All children with gestational age of 22-27 completed weeks or birth weight of 500-999 g born in the years 1999-2000 in two counties of Western Norway (n = 52) were invited to an eye examination that included visual acuity, refractive error, binocular function, accommodative amplitude and fundus examination. Cognitive function was assessed with the WPSSI-R test and motor abilities with the ABC movement test. Results: Neonatal morbidities and neurodevelopmental outcome were known for all, while 37 of the 52 children underwent the eye examination. None were blind or visually impaired, but 46% had subnormal visual acuity (logMAR ‡0.1). Ninety per cent were emmetropic or slightly hypermetropic (0 to +3D), while 10% had manifest and 51% latent strabismus. Performance IQ on the WPSSI-R test and ABC total score were associated with best visual acuity (p = 0.03 and p < 0.01, respectively). In a multiple linear regression model, visual acuity in the best eye was significantly associated with performance IQ (p = 0.03) and ABC total score (p = 0.02). Conclusion: This study suggests a more favourable long-term prognosis on important ocular and visual parameters in survivors of extreme prematurity than expected from similar reports on children born less prematurely and that performance IQ and motor function are related to visual acuity.
