This study was a multicenter, non-interventional, retrospective chart review of patients with DME who received ranibizumab 0.5 mg as initial intensive treatment in real-world clinical setting in Korea. Enrolled patients started receiving ranibizumab between 01 December 2019 and 31 October 2020, with records of receiving at least 3 doses in the first 4 months after starting treatment in the data collected until 30 April 2021. Subsequent dosing interval was determined by the treating physician based on the patient's condition. Data were collected for up to 24 weeks (±2 weeks) from the date of first dose of ranibizumab, including best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) results at Week 24. Subjects were identified by review of patient medical records, and those who met the inclusion/exclusion criteria were enrolled. The primary objective of this study was to evaluate the effectiveness of ranibizumab in patients with DME who received initial intensive treatment by analyzing the mean change in BCVA using data collected during the 24-week follow-up period. Central subfield thickness (CST), intra-retinal fluid (IRF), sub-retinal fluid (SRF), edema improvement, and Diabetic Retinopathy Severity Scale (DRSS) results were also assessed to further analyze the effectiveness of ranibizumab. The total number of ranibizumab doses administered was obtained to determine the pattern of ranibizumab treatment in real-world clinical setting. All decisions regarding the clinical management and treatment of patients were made by the treating physician according to real-world routine practice, independently of the study. All data collected in this study were extracted from the patient medical records recorded in the process.
