Purpose: To compare the reliability of office versus remote assessments in the decision to use intravitreal injection for patients with diabetic macular edema (DME)., Method: We retrospectively evaluated office and remote assessments for decision agreement regarding treatment by intravitreal injection or non-treatment for DME. Remote assessment consisted in remote evaluation of patient medical data by three reviewers with different skills. Two OCT analysis strategies were performed with the same office assessment data: 1) macular mapping with only two OCT B-scans passing through the fovea, and 2) macular mapping with complete macular scans. Agreement for treatment decisions and OCT analysis strategies were analysed using Cohen's Kappa coefficient (κ)., Results: Data from 49 patients (96 eyes) were included. Treatment decision agreement with two OCT B-scans passing through the fovea was considered excellent for all reviewers (κ between 0.80 and 0.85, varying between reviewers). Treatment decision agreement with complete macular scans was considered excellent (κ between 0.85 and 0.93, varying between reviewers). Agreement between the two OCT analysis strategies and reviewers was considered excellent., Conclusion: Remote assessment in a telemedicine model can be a useful alternative for DME patient follow-up.
