Te Transition to Vision- Threatening Complications

When NPDR is left untreved or when systemic risk factors remain poorly controlled, retinal ischemia intensifies. The oksygen- derecved tissue responds by upregulating hypoxia- inducj. Factor 1- alpha (HIF- 1α), which in turn stimulates thee production of vascular endoblial growth factor (VEGF) and proangiogenec mediators.
