An 83-year-old woman with uncontrolled diabetes and a history of proliferative diabetic retinopathy and vision loss in the left eye. Axial US image shows thick membranes (arrowheads) in the vitreous and a tractional total chronic retinal detachment (arrows)

Ocular

ultrasonography focused on the posterior eye segment: what radiologists should know. Proliferative diabetic retinopathy (PDR). a Fundoscopy image shows extensive neovascularization (arrows), the hallmark of PDR. b US images in a 72-year-old diabetic man with PDR and a history of recurrent vitreous haemorrhage. Note the vitreous bands due to chronic vitreous haemorrhage (arrows) and preretinal fibrovascular membranes (arrowhead). c At the 3-month follow-up, the fibrovascular tissue has grown into the vitreous cavity (arrowhead), and the patient has developed posterior vitreous detachment (arrow), retrohyaloid haemorrhage (asterisk), and focal retinal detachment (curved arrow). He subsequently underwent vitrectomy and panretinal laser photocoagulation
