Case in brief
A 6-year-old boy presented with frequent daily episodes of isolated right upward eye deviation, lacking other ictal features such as impaired awareness or visual symptoms. Neurological and ophthalmological evaluations were normal, and brain MRI showed no abnormalities. Video-electroencephalography revealed spike-wave discharges in the left occipital region, confirming an epileptic origin. Treatment with carbamazepine significantly reduced the frequency of episodes, which resolved completely after dose adjustment.
Diagnostic / clinical pearl
Isolated paroxysmal eye deviation in children can indicate focal seizures with preserved awareness, necessitating early EEG evaluation to prevent misdiagnosis.
Why it matters
This case underscores the importance of recognizing atypical presentations of epilepsy in children, which can lead to timely and appropriate management.
