Bilateral Optic Disc Edema in a Patient with Lead Poisoning

Purpose: Heavy metals like lead are one class of toxic agents that can cause optic neuropathy.Methods: We report a 42-year-old male who, due to lead poisoning, had been treated with lead chelators. Results: He had gradually developed blurred vision in both eyes over 40 days. He had ataxia and paresthesia and a toxic level of serum lead. He had decreased visual acuity in both eyes which involved color vision. Humphrey’s Visual Fields test revealed a double arcuate scotoma with enlargement of the blind spot. In funduscopy he was found to have bilateral optic disc edema which was confirmed by optical coherence tomography and fluorescein angiography.Conclusion: This is the first case reported with these specific impairments
