Abstract
Brain tumors in children often involve the visual system, but most retrospective series are by neurologists or oncologists. In this study we highlight the ophthalmic findings of outpatient children with visual complaints and/or strabismus who, based on ophthalmic examination, were suspected to and confirmed to harbor intracranial space-occupying lesions by magnetic resonance imaging (MRI).
Retrospective case series of children (less than 18 years) who for visual complaints and/or strabismus underwent cranial MRI at a referral eye hospital (2005-2012), which revealed intracranial space-occupying lesions. Exclusion criteria were known preexisting orbital or ocular trauma, ocular tumor, or neurological disease.
For 26 patients (3 months-17 years; mean 7 years; median 9 years; and 14 boys), the most common clinical presentation was decreased vision with disc pallor (10) or swelling (three). Other presentations were strabismus with disc pallor or swelling (four; two of which were left sixth nerve palsies), acquired esotropia with diplopia (three; one bilateral and two left sixth nerve palsies), acquired exotropia (four; two of which were bilateral third nerve palsies, one of which was left partial third nerve palsy, and one of which was associated with headache), nystagmus (one), and disc swelling with headache (one). Most lesions were in the sellar/suprasellar space (10), posterior fossa (six), or optic nerve/chasm (four).
The majority of outpatient children diagnosed by ophthalmologists with intracranial space-occupying lesions presented with disc swelling or pallor in the context of decreased vision or strabismus. Two strabismus profiles that did not include disc swelling or pallor were acquired sixth nerve palsy and acquired exotropia (with ptosis (third nerve palsy), nystagmus, or headache).
