Abnormal eye movements or
suspected loss of vision
Visual abnormalities are common in babies and young children – most are not caused by a brain tumour.
The most common visual abnormality in babies and young children is a squint, in which the two eyes do not look in the same direction. Squints are very rarely caused by a brain tumour, but do require assessment by an ophthalmologist when first noted.
Abnormal appearance or movements of the eye are an important symptom to look out for – for example, if one eye is bulging, or if the eyes appear wobbly, quivering or flicking.
