Objective: To study the relation of C-Reactive Protein (CRP), Erythrocyte Sedimentation Rate (ESR) and Body
Mass Index (BMI) with diabetic retinopathy in patients enrolled from a tertiary care hospital.
Study Design: Cross sectional comparative study.
Place and Duration of Study: Centre for Research in Experimental and Applied Medicine (CREAM-1) at
Department of Biochemistry and Molecular Biology, Army Medical College, Rawalpindi in collaboration with
Armed Forces Institute of Ophthalmology (AFIO), Rawalpindi over a period of 6 months from Jan 2016 to Jun
Material and Methods: There were 90 patients of diabetic retinopathy enrolled from AFIO. Their ages were in
range 40-70 years. Their levels of ESR, CRP and BMI were assessed. These were then compared with 90 normal
healthy controls from general population. Independent student’s t-test was applied for scale variables and Chi
square test was applied for nominal variables.
Results: Patients and controls were age and gender matched. Their mean ages were 60 ± 8.9 years in patients and
59 ± 13.02 years in controls. In 90 patients enrolled 51 (56.7%) were males and 39 (43.3) were females. And in 90
controls considered 49 (54.4%) were males and 41 (45.6%) were females. Both scale variables gave following
results ESR= 27.9 ± 6.96 in patients and 16.02 ± 7.6 in controls with a p-value of
Body mass index, C-reactive protein, Diabetic complications, Erythrocyte sedimentation rate
