Peripheral non perfusion in diabetic retinopathy

 Peripheral non perfusion in diabetic retinopathy

By Ameen Marashi

When examining a patient with Diabetic retinopathy it is important to examine the peripheral funds specially using fluorescein angiography which tells us the perfusion status of the peripheral retina and thus can be important prognostic factor of progression of diabetic retinopathy.

The peripheral retina can be either normal, areas of non perfusion with non proliferative diabetic retinopathy , or proliferative diabetic retinopathy with or without areas of non perfusion.

As we all know that areas of non perfusion may increase VEGF which can lead to proliferation and thus may cause the risks of visual loss due to vitreous hemorrhage and/or tractional retinal detachment.

So when we find high risk proliferative diabetic retinopathy or areas of non perfusion ( capillary drop out on FFA) with or without proliferative diabetic retinopathy it is important to treat those patients with PRP by pacing laser burns in the areas of non perfusion to reduce the VEGF that is induced by ischemia and to preserve as much as possible of visual field.
