Tractional Retinal Detachment Due To Diabetic Retinopathy

Strong linear reflection involving the posterior globe nasal and temporal to the optic nerve. Vitreous is attached to this linear object. There is no secondary motion, consistent with tractional retinal detachment.

High reflectivity (strong mismatch in acoustic impedance) of the linear structure consistent with a tractional retinal detachment involving the macula and nasal area around the optic nerve.  

Movement of the probe reveals the degree of macular involvement.
