Abstract [en]

AimTo investigate the ophthalmological outcome of very preterm children at 2.5years corrected age (CA) and perform a test of visuospatial and cognitive abilities. MethodsA population-based, prospective study (LOVIS study) in Uppsala County, Sweden, comprised 111 very preterm children (<32 w gestational age [GA]) born between 1 January 2004 and 31 December 2007. Ophthalmic evaluations were undertaken in 98/109 children (89.9%) alive at 2.5 years. Spatial cognition was investigated with a test of five alternative blocks in 48 preterm and 25 term-born children. ResultsVisual impairment, strabismus or refractive errors, were found in 12% of the children. None of the children were blind in both eyes. Logistic regression analyses revealed significant associations between strabismus and periventricular leucomalacia/intraventricular haemorrhage (OR 9.6, p=0.025) and between refractive errors and severe retinopathy of prematurity (OR 9.8, p=0.011) and GA (OR 0.763, p=0.034). Oval and rectangular blocks were significantly more difficult to insert into a box for preterm than full-term children (p=0.048 and 0.013, respectively). There was a significant correlation between total scores for the five blocks and GA at birth (p=0.035). ConclusionEye and visual problems were found in 12% of the preterm children at 30months CA. Preterm children had difficulties with blocks of complex shapes.
