Patients with physical signs and symptoms for which no adequate organic cause can be found may receive a wide range of diagnoses, and represent a diagnostic challenge with medical and legal implications. Twenty five to fifty percent of patients with apparent nonorganic visual loss have concomitant organic pathology that explains at least some visual deficit. Additional difficulty is the best selected medical term to call it, and this is our objective in this review. In the light of the current knowledge and after evaluating several alternatives, we consider that the best term for them is nonorganic losses of vision. Nonorganic visual loss is never a excluding diagnosis; positive findings are required to make the diagnosis. The clinical method (visual psychophysics) and certain diagnostic tools in addition to some clinical ones are sufficient to set a diagnosis of nonorganic ocular disease in the majority of cases.

Palabras clave : non-organic visual loss; diagnostic tests.
