PURPOSE: To investigate associations among expanded field swept-source optical coherence tomography angiography biomarkers and the development of tractional retinal detachment (TRD) in patients with proliferative diabetic retinopathy (PDR).
METHODS: Patients with PDR without TRD at baseline were imaged with swept-source optical coherence tomography angiography. Quantitative and qualitative OCTA metrics were independently evaluated by two trained graders. A logistic regression model was used to identify OCTA biomarkers associated with TRD development.
RESULTS: Forty-nine PDR eyes from 38 participants were included. Seven of 49 eyes (14%) developed TRD over a median of 576 (range 35-805) days. Biomarkers associated with TRD were large retinal nonperfusion area (odds ratio [OR], 7.84; 95% confidence interval [CI], 2.61-16.3; P = 0.04), presence of neovascularization (NV) with total area > 4 disc diameters (OR, 2.30; 95% [CI], 1.09-4.51; P = 0.04), and presence of tabletop NV (OR, 2.64; 95% [CI], 1.42-4.86; P = 0.02), defined as NV displaced anteriorly by vitreous traction but tethered to the retina by vascular membranes.
CONCLUSION: Presence of large retinal nonperfusion area, extensive NV, and NV with features of anterior displacement by vitreous traction were associated with increased risk of TRD occurrence. Swept-source optical coherence tomography angiography may be useful for predicting diabetic TRD development.
