	abstract = {PURPOSE: The aim of this study was to compare patient-reported symptoms of dry eye disease (DED) as assessed by the Ocular Surface Disease Index (OSDI), a 12-item symptom frequency-based questionnaire, and the Symptom Assessment iN Dry Eye (SANDE), a 2-item frequency- and severity-based visual analog scale. DESIGN: Clinic-based evaluation of a diagnostic test. PARTICIPANTS: A total of 114 patients with DED. METHODS: Patients were administered the OSDI and SANDE questionnaires at baseline and follow-up visits to evaluate DED-related symptoms. The correlations between both questionnaires{\textquoteright} scores were evaluated using the Spearman coefficient, and their clinical differences were assessed using Bland-Altman analysis. MAIN OUTCOME MEASURES: Baseline and follow-up visit OSDI and SANDE dry eye symptom scores. RESULTS: At the baseline visit, the OSDI and SANDE questionnaire scores were significantly correlated (R\&nbsp;=\&nbsp;0.64; P \&lt; 0.001). Moreover, a significant correlation was found between changes in the OSDI and SANDE scores from baseline to follow-up visits (R\&nbsp;= 0.47; P \&lt; 0.001). A Bland-Altman analysis, after score normalization, revealed a difference (bias) of less than 2 centesimal units between the scores of the 2 questionnaires. CONCLUSIONS: Data collected from the SANDE questionnaire showed a significant correlation and negligible score\&nbsp;differences with those from the OSDI, suggesting that the SANDE visual analog scale-based questionnaire has\&nbsp;the potential to provide clinicians with a short, quick, and reliable measure for DED symptoms.},
