Abstract : To determine the relationship between diabetic retinopathy (DR) and diabetic peripheral neuropathy (DPN), and their associated risk factors. Methods: We conducted a cross-sectional analysis on 500 patients who attended the Endocrinology department at a quaternary health care center in Kerala between November 2017 and April 2018. Patients above the age of 30 years with type 2 diabetes mellitus (DM) were included. They underwent a detailed medical history, dilated fundus examination for DR, assessment and grading of DPN, and blood investigations. Among these, 49 randomly selected patients without DR had peripapillary retinal nerve fiber layer (RNFL) and ganglion cell inner plexiform layer (GCIPL) assessed by optical coherence tomogram. RNFL and GCIPL changes in different grades of neuropathy were evaluated. Results: Out of 500 patients, 303 (60.6%) were males and 197 (39.4%) were females. Prevalence of DR was 48% and DPN 71.8%. Risk factors for the development of DR included duration of DM >15 years, HbA1c (glycated hemoglobin) greater than 6.5%, serum creatinine more than 1.5 mg/dl, and the presence of DPN. There was a statistically significant association between DR and DPN. There was significant thinning of GCIPL in patients with moderate to severe neuropathy without DR.
