PURPOSE: To investigate the feasibility of remote assessment and follow-up of dry eye symptoms using electronic versions of two validated questionnaires. METHODS: We conducted a prospective study of consecutive patients with dry eye disease (DED). Patients were enrolled during a clinical visit and were explained how to respond electronic versions of the Ocular surface Disease Index (OSDI) and the Symptom Assessment in Dry Eye (SANDE) questionnaires using a computer in the presence of investigators. A secure link to both questionnaires was sent to each patient every 2 weeks in order to respond and submit their symptoms over a 3-month period. We analyzed the number of patients who responded to both questionnaires, the recurrence, and the symptoms scores reported. RESULTS: A total of 1121 questionnaires were collected; 103 patients (85%) reported their symptoms at least once during the 3-month study duration. The majority of participants who completed the study (71.6%) responded remotely at least once per month during the 3-month duration of the study. The mean OSDI and SANDE scores from the total of remote evaluations were 34.9 ± 21.9 (range 0-97.5) and 50.3 ± 24.9 (range 0-100), respectively. There was a statistically significant correlation between the total scores collected with the two questionnaires (R = 0.67, P < 0.001). CONCLUSIONS: Patients are motivated to report DED symptoms while away from the clinic. Distance-based evaluation of DED symptoms is both feasible and convenient, and can be implemented to follow symptoms in large populations with chronic dry eye.
