There was no significant difference between worst-eye DR/DMac grade and HbA1c, gender, body mass index, pancreatitis etiology and screening attendance (p\>0.05). Patients with proliferative DR had longer diabetes and pancreatitis duration than DR-free patients (both p=0.001).Conclusions DR prevalence was similar in PwDMsCP and patients with type 2 diabetes of similar disease duration. This work demonstrates the importance of reaching all patients for establishing DR severity reliably and to provide accessible, equitable care to PwDMsCP.Data are available upon reasonable request.}, URL = {https://drc.bmj.com/content/9/1/e002267}, eprint = {https://drc.bmj.com/content/9/1/e002267.full.pdf}, journal = {BMJ Open Diabetes Research and Care} }
