RT Journal Article SR Electronic T1 Screening attendance, prevalence and severity of diabetic retinopathy (DR) in a cohort of patients with diabetes mellitus secondary to chronic pancreatitis (DMsCP) in Northern Ireland JF BMJ Open Diabetes Research & Care JO BMJ Open Diab Res Care FD American Diabetes Association SP e002267 DO 10.1136/bmjdrc-2021-002267 VO 9 IS 1 A1 Catherine Jamison A1 Tunde Peto A1 Nicola Quinn A1 Rossella D’Aloisio A1 Laura Nicole Cushley A1 Philip C Johnston YR 2021 UL http://drc.bmj.com/content/9/1/e002267.abstract AB Introduction This study investigated Northern Ireland Diabetic Eye Screening Programme (NIDESP) attendance and diabetic retinopathy (DR) prevalence/severity in patients with diabetes mellitus secondary to chronic pancreatitis (PwDMsCP).Research design and methods Medical/NIDESP records for all PwDMsCP attending the pancreatic diabetes clinic were analyzed in 2017 (n=78) and 2019 (n=94).Results Between 2017 and 2019, those without DR decreased (76% to 63%); mild non-proliferative DR (NPDR), severe NPDR and PDR were found in 30%, 2% and 5%, respectively (previously 18%, 4%, 2%); diabetic maculopathy (DMac) was present in 12% (previously 10%). 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.
