Inclusion Criteria
- Age : Above 40 years old
- Type of DM: Type 2.
- Fundus examination: no macular edema or other signs of clinical retinopathy
Exclusion Criteria
- Age : below 40 years old
- Ocular history : any history of significant ocular injury or disease that could affect the retinal microvasculature such as retinal vascular occlusion, glaucoma, or vitreo-macular disease, as such conditions have also been noted to show sub-clinical OCTA changes [13, 14].
