Early peripapillary neurovascular injury and its relevant systemic factors in type 2 diabetic patients without retinopathy: An OCTA based study

Peripapillary NVU assessment may be valuable for diagnosing, monitoring and intervening in retinal microvascular and microstructural changes associated with DM. HbA1c level and renal function indicators represented by blood urea and eGFR, were the most important systemic factors underlying peripapillary NVU changes.
