Vogt Koyanagi Harada disease with bilateral disc edema diagnosed as Arnold Chiari malformation with papilledema: The blurred margin between ophthalmology and neurology.

A 33-year-old male presented with bilateral, painless diminution of vision. During a previous ophthalmic consultation elsewhere, he was diagnosed with papilledema. Neuroimaging revealed an Arnold Chiari Type 1 malformation, and an urgent neurosurgical intervention was performed. Currently, ophthalmic examination revealed an anterior chamber reaction, vitritis, optic disc edema (ODE), and exudative retinal detachment in both eyes. He was clinically diagnosed with Vogt-Koyanagi-Harada disease and treated with high-dose intravenous methylprednisolone, followed by immunosuppression, resulting in a favorable visual outcome. This case highlights the need for careful ophthalmic evaluation in cases of bilateral ODE before labeling it as "papilledema."
