Progression of diabetic tractional retinoschisis by optical coherence tomography

A 63-year-old woman presented with proliferative diabetic retinopathy with extensive posterior neovascularization in both eyes. Visual acuities were 20/40 in the right eye and 20/400 in the left eye with eccentric fixation. Tractional retinoschisis in the left eye that initially spared the fovea progressed over 3 years to involve the entire macula. Findings were documented by optical coherence tomography. No surgical intervention was offered. Tractional retinoschisis in proliferative diabetic retinopathy may become progressive due to cicatricial contraction of the posterior hyaloid face.
