Impact of Diabetes Mellitus on Retinal Microvasculature in Patients Without Clinical Retinopathy Using Optical Coherence Tomography Angiography

Impact of Diabetes Mellitus on Retinal Microvasculature in Patients Without Clinical Retinopathy Using Optical Coherence Tomography Angiography

the aim of this study is to assess the impact of duration of DM on OCTA parameters in diabetic patients without clinical Diabetic retinopathy.

Inclusion Criteria:

1. Type of DM: Type 2.
2. Fundus examination: no macular edema or other signs of clinical retinopathy

Exclusion Criteria:

1. 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].
2. Fundus examination: macular edema or any other signs of clinical retinopathy
