Vertigo is an underestimated symptom of ocular disorders: dizzy children do not always need MRI.
Vertigo, instability, dizziness, or equilibrium disorders are not usually considered as consequences of ophthalmologic problems. We present data indicating that ocular disorders can be responsible for these symptoms in children. In a population of 523 pediatric patients with vertigo or disequilibrium and referred for vestibular testing in our otolaryngology department during a 5-year period, 27 children presented with normal vestibular and somatic neurologic examinations but with ophthalmologic disorders (vergence insufficiency or latent strabismus with binocular vision in 70% and anisometropia in 41%). These patients represented 24% of all vergence insufficiencies detected and 4% of all orthoptic examinations performed in the pediatric ophthalmology department. These ocular abnormalities were considered to be the initial cause of the problems. In two thirds of these patients the symptoms were completely resolved by simple ophthalmologic treatment. No other additional tests, such as magnetic resonance imaging, were required. Therefore we propose that every child complaining of vertigo or dizziness but with normal clinical somatic neurologic and vestibular examinations should have a complete ophthalmologic examination before additional, more costly, investigations. This should lead to better screening and more appropriate care of ocular disorders in children and avoid unnecessary magnetic resonance imaging.
