Early worsening of diabetic retinopathy due to intensive glycaemic control

Abstract

The prevalence of diabetes and diabetic retinopathy is increasing around the world. Glycaemic control is important in reducing the long-term risk of complications of diabetes, however intensive glycaemic control, particularly in patients with longstanding and poorly controlled diabetes, is associated with the risk of early worsening of diabetic retinopathy and vision loss. We present two clinical cases to illustrate the presentation of early worsening and to highlight a role for intravitreal anti-vascular endothelial growth factor therapies in ameliorating this phenomenon, as well as a review of the current understanding of this phenomenon. We emphasise the importance of identifying individu..
