Pan-retinal laser photocoagulation (PRP) is a procedure in which laser burns are placed over the peripheral retina, sparing the central macula. It is the gold standard treatment for proliferative diabetic retinopathy (PDR), an advanced stage of diabetic retinopathy characterised by the development of retinal neovascularisation (1,2). PDR is very often asymptomatic and patients may retain good vision despite existing retinopathy hence the need for regular annual photographic screening. PRP has been shown to reduce the risk of severe visual loss by 50% in patients with PDR (2,3). This article demonstrates the use of PRP laser therapy in the clinical setting of a rare case of severe and extensive PDR.
