Abstract:
The diagnosis of feigned vision loss in adults taxes the doctor-patient relationship because the relationship should be based on trust, honesty, and the mutual desire to improve the medical condition. Even under ideal circumstances, physicians rarely have a complete understanding of the factors that lead patients to simulate disease they do not have. We describe the historical figure of John Howard Griffin (1920-1980) who likely perpetuated feigned vision loss for a decade. His writings provide a unique perspective on motivation (or inspiration) behind factitious disease.
