Introduction: Platelets are tiny, disc-shaped, non-nucleated structures derived from megakaryocytes. The morphological differences in measuring Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) of platelets have important implications for assessing the functional expressions of platelets. Electron microscopy reveals the presence of glycogen as prominent masses in platelets. MPV values have been generally reported to be very high in individuals with uncontrolled diabetes mellitus (DM).

Aim: This study aimed to determine and compare the MPV values in uncontrolled and controlled group of Type-2 Diabetics along with healthy non-diabetic people and to correlate MPV values with age, sex and glycosylated haemoglobin (HbA1c) levels in diabetic groups. This study also aimed to determine the prevalence of retinopathy in uncontrolled and controlled group of diabetic patients.

Materials and Methods: This case control study was carried out in our institution for 1 year. The patients were grouped as uncontrolled group of diabetic patients and controlled group of diabetic patients based on their HbA1c levels. 106 uncontrolled diabetic patients and 100 controlled diabetic patients were included, with 100 non-diabetic subjects as controls. Patient’s profile which included all demographic particulars and medical history was obtained. Fundus examination and other ophthalmic findings of 50 uncontrolled and 50 controlled diabetic cases were recorded. The findings were analysed statistically using IBM SPSS software.

Results: In uncontrolled group of 106 diabetic patients, 54 patients were males and 52 patients were females and the mean age was 51.63±11.04, mean HbA1c was 9.86±1.91% and mean MPV was 8.93±0.90fl. In controlled group of 100 diabetic patients, 49 patients were males and 51 patients were females and the mean age was 47.88±15.17, mean HbA1c was 6.08±0.49% and mean MPV was 8.106 ± 0.72fl. In 100 non-diabetic controls 77 patients were males and 23 patients were females and the mean age was 37.97±9.69 and mean MPV was 8.02±0.86fl. Among 50 cases of uncontrolled DM, 14 uncontrolled DM patients had diabetic retinopathy with an average MPV of about 9.2±0.61fl and mean HbA1c of 10.6±1.98% whereas, 30 uncontrolled patients with no evidence of retinopathy with an average MPV of about 8.39±0.676 fl and mean HbA1C of 9.18±1.91%.

Conclusion: MPV values are higher in uncontrolled DM patients when compared with controlled DM patients and a higher percentage of them develop microvascular complications like Diabetic Retinopathy suggesting that mean platelet volume could indicate and play a more important role in the detection of vascular complications of Diabetes.
