Amiodarone-related optic neuropathy.
BACKGROUND
To evaluate a case of atypical optic neuropathy that presented with blurred vision following the use of an antiarrythmic agent.


METHODS
Record of the patient was reviewed to determine the etiology of his optic neuropathy.


METHODS
Ophthalmological examination revealed unilateral optic disc edema with relatively well-preserved visual acuity. In routine tests, results of complete blood count, erythrocyte sedimentation rate, liver and kidney function tests, chest x-ray, Goldmann visual field examination, and brain computed tomography scan were normal. Orbital ultrasonography revealed optic disc edema with prominent optic nerve head and without orbital pathology.


CONCLUSIONS
Systemic history and drug intake should be investigated in every patient with optic disc edema. Discontinuation of the medication can prevent further optic nerve damage or involvement of the other eye.
