Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To determine the correlation between the changes observed in the nailfold capillaries and the retinal microvasculature in non-diabetic controls, Diabetes Mellitus with and without RetinopathyTimepoint: 24 months | — |
Secondary
| Measure | Time frame |
|---|---|
| To grade the nailfold capillary changes across different stages of diabetic retinopathyTimepoint: 24 months;To identify potential predictive markers in the nailfold capillaries that may indicate early microvascular changes in the retina for early diagnosis of Diabetic RetinopathyTimepoint: 24 months;To assess the clinical utility of Optical Coherence Tomography-Angiography (OCT-A) in identifying early retinal microvascular changes and its correlation with systemic microvascular alterations detected by nailfold imaging device in diabetic retinopathy patientsTimepoint: 24 months | — |
