PP06.1 – 2574: Aetiologies of CVI in Mainstream Secondary Education

Abstract

Objective To study the aetiology of the brain dysfunction in children with CVI (cerebral visual impairment) in mainstream secondary education. Methods A retrospective study in children with CVI in mainstream secondary education is performed. 19 Children are included, 7 male/12 female. Mean age is 15 years, from 13 years to 18 years. The visual acuity of the best eye is 10/10 in 10 children, the lowest acuity measured is 1.6/10 and mean visual acuity is 8/10. 26% had another ophtalmological diagnosis (5/19), e.g. cataract or retinopathy of prematurity. IQ was good: total mean 90, from 72 to 127. 79% suffered from comorbidity, e.g. DCD and ASD. 20 Children with CVI, who attend special education are not included in this study. Results 63% have perinatal problems (12/19). Only 4 are born premature. The lowest gestational age is 29/40, with a birth weight of 1100 g. In 4 term children problems during delivery are reported. Only very few is known about neonatal hypoglycaemia and CVI. In only 1 child neonatal hypoglycaemia is reported. In all the other children information on neonatal glycaemia is lacking. The periventricular leukomalacia on MRI images of children with neonatal hypoglycaemia is very similar to what is seen in children with CVI. 37% have no history of any perinatal problem (7/19). The aetiologies in these children are tumour, meningitis, head injury, hypoxia at later age, turner syndrome or an arteriovascular malformation. Conclusion The children with CVI in mainstream education have less disabling aetiology than those reported in literature. They have the same % of comorbidity, but less severe comorbidity. They have better visual acuity. They compensate due to good IQ. In the future we will study the children with CVI who follow special education in order to compare whether they have different aetiologies than those in mainstream education.
