Abstract
Purpose: The purpose of this retrospective study was to evaluate the disorganization of the retinal inner layers (DRIL) as a potential predictive factor of postoperative visual outcome in patients with idiopathic epiretinal membrane (iERM), treated with pars plana vitrectomy (PPV). Methods: Participants in the study were 46 consecutive patients diagnosed with iERM, who underwent PPV. Best corrected visual acuity (BCVA) measurement and spectral-domain optical coherence tomography (SD-OCT) were performed at baseline (preoperatively), and at months 3 and 6 postoperatively. DRIL and additional OCT parameters were assessed at 1-mm-wide foveal centered area. Results: DRIL was observed in 47.8% of patients at baseline. There was statistically significant improvement in BCVA and central retinal thickness (CRT) between baseline and months 6 and 12 in all patients. There was a statistically significant difference in BCVA and CRT change between patients with and without DRIL at months 6 and 12 compared to baseline, showing that there was a correlation between change in BCVA or CRT and baseline DRIL. Ellipsoid zone and external limiting membrane were intact in 91.3 and 95.7%, respectively, not affecting our results. Conclusions: Baseline DRIL has been shown to be predictive of postoperative visual outcome in patients with iERM, treated with PPV. [ABSTRACT FROM AUTHOR]
