DESIGN: Interventional case report. METHODS: Institutional setting. RESULTS: Corneal lesions were much more diffuse than those observed in adult Cogan syndrome. Immunosuppressive drug combination therapy successfully resolved systemic and ocular inflammation, but the involvement of the pupillary area caused permanent low vision in one case and amblyopia in the other. CONCLUSION: When chronic ocular inflammation is observed in association with sensory neural hearing loss and any systemic signs of autoimmune inflammation, a diagnosis of Cogan syndrome should be suspected. If immunosuppressive treatment is not initiated as soon as possible, permanent low vision and deafness can result.
