Stability of macular traction in involutional diabetic retinopathy over a 5-year course.

Involutional diabetic retinopathy is a descriptive term for an end-stage phase of proliferative diabetic retinopathy (PDR), which is often non-progressive. Two patients with involutional PDR with nonprogressive macular traction documented by spectral-domain optical coherence tomography (SD-OCT) over a 5-year period are described in this report.
