• ERM peeling is an anatomically and functionally successful surgery in terms of visual improvement and retinal displacement in both iERMs and dERMs. • The presence of pre-operative SF and DRILs were higher in dERMs. • The presence of DRILs was associated with lower visual acuity in the dERM group. To compare the postoperative retinal displacement by optical coherence tomography (OCT) in idiopathic epiretinal membranes (iERM) and diabetic epiretinal membranes (dERM). This retrospective study included 36 iERM and 22 dERM cases. In cross-sectional OCT images (B-scan) the presence of foveal pit, subfoveal fluid, cotton ball sign (CBS), intraretinal cystic changes (ICC), disorganization of retinal inner layers (DRILs) and ectopic inner foveal layer (EIFL) were recorded. Central macular thickness (CMT) and EIFL thicknesses were calculated. Retinal displacement was quantified using infrared image of OCT approach consisting of the fovea to disc margin, interarcade distance and perimacular distances. The presence of subfoveal fluid (p = 0.014) and DRIL (p = 0.02) was significantly higher in the dERM group. CMT decreased significantly in both groups (p˂0.001). The EIFL was significantly thicker in the iERM group compared to the dERM group (p = 0.049), and it decreased significantly in the iERM group postoperatively. In the iERM group, while the fovea-disc margin distance decreased, the interarcade and perimacular distance increased significantly (p˂0.001). In the dERM group, the disc-fovea distance change was not significant (p = 0.082). Significant visual improvement was achieved with vitrectomy in both groups (p˂0.001). In the dERM group, the presence of DRIL was associated with lower pre and post-op visual acuity (VA) (r = 0.596 and p = 0.004 for pre-operative and r = 0.567 and p = 0.007 for post-operative). Significant retinal displacement occurs after vitrectomy in both iERM and dERM. The low VA in the dERM group may be related to the presence of DRILs. [ABSTRACT FROM AUTHOR]

To evaluate ocular findings in central precocious puberty (PP). This prospective study included 38 children with PP and 34 healthy control children. All participants were evaluated in terms of refractive error, axial length (AL), and anterior segment parameters, including keratometry (K), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV), and iridocorneal angle (ICA). Central macular thickness (CMT), retinal nerve fiber layer (RNFL) thickness and central subfoveal choroidal thickness (ChT) were also analyzed. The correlation of these parameters with Tanner stage was also investigated in the PP group. Compared with the control group, spherical refraction was less hyperopic (P = 0.017) and AL was significantly higher (P = 0.001) in the PP group. Spherical value and AL were significantly associated with the Tanner stage. None of the anterior segment parameters obtained by Pentacam was different in the PP group compared with controls. In PP cases, CMT and RNFL thicknesses in all sectors did not differ from controls. Subfoveal ChT was significantly higher in the PP group, regardless of Tanner stage (P < 0.001). In our cohort of children with central PP, AL and ChT were higher than in children without PP.▪ [ABSTRACT FROM AUTHOR]
