Double hump appearance of TRD on widefield OCT

We report a unique case of double hump appearance on a widefield swept-source optical coherence tomography (OCT) scan in a 60-year-old diabetic man who underwent pars plana vitrectomy + photocoagulation for proliferative diabetic retinopathy-induced tractional retinal detachment (TRD). Ultra-widefield retinal imaging [Fig. 1a] shows ring-like fibrovascular proliferation above the disk, diffusely involving the posterior pole with peripheral laser scars. The redline depicts the slice navigator passing through the macula for widefield swept-source OCT. Widefield OCT [Fig. 1b] passing through the macula shows double hump formation due to broad-based vitreoretinal adhesions secondary to diffuse fibrovascular proliferation. Widefield OCT on Optos in diabetics has the advantage of highlighting the broad and high vitreoretinal adhesions, which are usually missed or not covered in a single OCT frame on other imaging modalities.Figure 1: (a) Widefield fundus photograph showing diffuse fibrovascular proliferation involving the posterior pole.
