Efficient capture of dry eye data from the real world: The Save Sight Dry Eye Registry

Abstract

Purpose

To describe a web-based, high-quality data collection tool able to track the clinical data of patients with dry eye disease (DED) in routine clinical practice.

Design

Retrospective analysis of core system web data from a prospectively designed, observational, routine clinical practice registry, the Save Sight Dry Eye Registry (SSDER).

Methods

Patients with DED, from 11-Nov-2020 to 04-Mar-2024 were analysed. Ocular Surface Disease Index (OSDI) and Ocular Comfort Index (OCI) questionnaires collected patient-reported DED symptoms, and the Patient Health Questionnaire-4 (PHQ-4) screened for anxiety and depression. Outcome data include index visit demography, DED symptoms and signs.

Results

Fifteen clinicians (ophthalmologists and optometrists) from nine practices across Australia, France, Germany, Nepal, Spain and the United Kingdom contributed data, comprising index visits of 958 eyes from 479 patients (mean±SD age 56±17 years; 78.7% female). Up to 89.9% of the patients had either evaporative or mixed DED based on clinician's judgement. Mean OSDI symptom score at index visit was 35.7 ± 19.4 (n = 366), and the mean sores for frequency and intensity of discomfort with the OCI was 31.9 ± 6.1 and 31.4 ± 6.8 (n = 202) respectively. Forty-one percent of patients had mild to severe symptoms of anxiety and depression. Median tear breakup time and tear meniscus height were 5 (IQR 2–8) seconds and 0.3 (IQR 0.2–0.4) mm, respectively. Ocular surface staining was graded as none (37.6%), minimal (31.7%), mild (19.8%), moderate (8.8%) and severe (2.1%).

Conclusion

The SSDER facilitated the collection of data from patients with DED from real-world clinical practice. Presenting patients had moderate DED, which was mostly evaporative in nature. Symptoms of anxiety and depression were reported by more than one-third of the cohort.
