Purpose This study aimed to demonstrate the value of the chief compliant and patient history to accurately diagnose patient pathology without requiring ocular examination or imaging in an outpatient neuro-ophthalmology clinic. Methods We prospectively evaluated 115 consecutive patients at our institution from January to April 2009. The attending neuro-ophthalmologist committed to a single most likely diagnosis while solely being exposed to patient demographic information (age, gender, race) and chief complaint, but was otherwise blinded to ocular examination or imaging. The validity of the initial diagnosis was assessed by further acquiring subjective and objective findings and the percentage of correct diagnoses was determined. Results Patient cases were categorized based on the neuro-ophthalmologic localization of the final diagnoses: afferent nervous system, central nervous system (CNS), efferent nervous system, orbital system, and pupillary system. Correct diagnoses by chief complaint and patient history were 84%, 100%, 86%, 80%, 50% and 100% for afferent, central, efferent, orbit, pupil, and other neuro-ophthalmic diseases, respectively. Over half the cases were correctly diagnosed by chief complaint alone, which improved to 88% when combined with the patient history. Conclusions A simple combination of patient history and chief complaint predicts an overall diagnostic accuracy in approximately 90% of cases. Our study demonstrates the remarkable diagnostic value of patient history in neuro-ophthalmologic clinic practice.
