Patients who recover generally do so in a particular sequence. Improvement of ocular abnormalities is the earliest and most dramatic, usually occurring within hours of the initial thiamine dose. Failure of ocular abnormalities to respond to thiamine in this manner should raise doubt as to the veracity of the diagnosis.
