Spectral-domain optical coherence tomography findings of tractional retinal elevation in patients with diabetic retinopathy

To evaluate the clinical and morphological characteristics as well as the surgical outcomes of tractional retinal elevation (TRE) in patients with proliferative diabetic retinopathy (PDR) by analyzing spectral-domain optical coherence tomography (SD-OCT). SD-OCT images of 26 eyes (24 patients) who visited our clinic because of TRE and PDR from August 2011 to August 2014 were reviewed. According to the presence or absence of tractional retinal...
