[Visual motor and visual defects in spina bifida]

Among the numerous problems that spina bifida (SB) patients are faced with, impairments to the visual apparatus are often considered late and are not covered extensively in the literature. At the Pediatric Department of the University of Padua, an assessment of the visual function of 59 SB patients between 5 months and 26 years of age (29 male and 30 female) has been carried out by means of an ophthalmologic protocol. As far as the alteration of the exstrinsic ocular mobility is concerned, 44% (26/59) of our patients revealed a manifest squint and only 3% (two patients) suffered from a latent squint. The most frequent type is a convergent squint (80%). The assessment of visual acuity made through Optotype was good in 82% of the cases (unlike what is commonly reported in the literature) and mild in 18%. None of the patients manifested hypovision. Refraction defects were present in 59% (34/59) of the patients. Regular ophthalmologic evaluations from birth or from diagnosis allow ophthalmologic treatments that are tailored to children suffering from SB and also enable them to reach and maintain a good visual standard and to observe the subtle symptoms of endocranial hypertension sooner. An early discovery and correct treatment of visual problems improves cognitive and motive performance as well as the autonomy of SB patients.
