Two cases of giant cell myocarditis with ocular symptoms.

Patient 1 with giant cell myocarditis was the first case at our hospital to present with ocular symptoms. Unfortunately, the patient died because cardiac arrest occurred before giant cell myocarditis could be diagnosed. In contrast, in Patient 2, our previous experience enabled us to suspect giant cell myocarditis earlier based on similar ocular symptoms. Thus, we were able to perform a myocardial biopsy and administer immunosuppressive drugs at an early stage. Thus, it is vital to understand that ocular symptoms may be indicative of giant cell myocarditis, and an urgent diagnosis is needed to prevent patient death.
