Tractional Retinoschisis in Proliferative Diabetic Retinopathy Imaged With Swept-Source Optical Coherence Tomography Angiography

Tractional retinoschisis (TRS) secondary to proliferative diabetic retinopathy (PDR) may be differentiated from tractional retinal detachment (TRD) by its characteristically nonprogressive course. The purpose of the current study was to describe the use of swept-source optical coherence tomography angiography (SS-OCTA) in the diagnosis and monitoring of TRS secondary to PDR. Retrospective, consecutive case series of patients with TRS secondary to PDR are featured. Clinical notes, fundus photography, and SS-OCTA images are reviewed. The study comprised three eyes of three patients with PDR and TRS. Visual acuity and anatomic features on SS-OCTA were stable in all patients at one year or more of follow-up. Tractional retinoschisis secondary to PDR is typically nonprogressive and may be observed without surgery. SS-OCTA serves as a noninvasive and effective imaging tool to distinguish TRS from TRD and to demonstrate anatomic stability over time.
