Re-evaluation of Magnetic Resonance and Computerised Tomographic Imaging in Neuro-Ophthalmic Patients in an Academic Centre

The aim of the study is to report the frequency of missed diagnoses on magnetic resonance and computerised tomographic imaging in neuro-ophthalmic patients who were referred to an academic ophthalmology department, with apparent normal imaging. The authors included all neuro-ophthalmic patients, referred to their department during a 5 1/2-year period. The neuroimaging of these patients were reviewed by a neuro-ophthalmologist side by side with a neuro-radiologist. In the study period, 75 neuro-ophthalmic patients were referred with an apparent normal scan. Re-evaluation of these images gave a diagnosis in 11 patients (15%). Meningiomas were missed most frequently. In half of these patients, no contrast was used in the primary studies. The authors conclude that neuro-ophthalmic pathology can easily be missed on routine neuroimaging studies
