Hyperglycaemia-Related Visual Seizure

INTRODUCTION: Visual seizure is one of the rare complications of poorly controlled chronic hyperglycaemia. This condition can be debilitating for patients. Early recognition and careful control of hyperglycaemia is vital. CASE DESCRIPTION: A middle-aged female was found collapsed at her home after missing insulin for several days. She was found to have diabetes ketoacidosis (DKA) and she was started on treatment for DKA. She reported visual hallucinations in the right side of her visual field for a week. Further assessment with EEG and brain MRI suggested an occipital seizure consistent with metabolic disturbances. She was initially started on antiepileptic medication. After strict diabetes control, her symptoms resolved, and she no longer needed antiepileptic treatment. CONCLUSION: Experiencing diabetes-related seizures can be terrifying both for patients and their family. Early recognition and quick control of hyperglycaemia is important in treating these patients. LEARNING POINTS: Hyperglycaemia can present with different symptoms of osmotic imbalance including seizures. All patients presenting with visual seizures should be investigates for all metabolic abnormalities including hyperglycaemia. Correction of hyperglycaemia can improve clinical symptoms as well as physical and psychological well-being of patients.
