Delamination: Separation of these membranes/FVP from the retinal surface to which they are firmly adherent by creating a plane of dissection between them. Pearl #1 When not to perform vitrectomy in diabetic retinopathy? Answer: In cases of extramacular tractional retinal detachment (TRD) when the fovea is attached and the patient has a comparative good vision the extramacular TRD can be observed.
