Purpose: The aim of this study was to investigate the repercussions of peripapillary detachment on retinal nerve fiber layer (RNFL) measurements in patients with highly myopic eyes.
Methods: A total of 244 highly myopic eyes underwent a complete ophthalmologic examination that included optical coherence tomography (OCT) to analyze the peripapillary retina and RNFL thickness. Based on the OCT findings, patients were grouped as follows: group A: eyes with a peripapillary intrachoroidal cavitation (PIC); group B: eyes with a peripapillary neurosensory retinal detachment (PNRD), and group C: eyes without a peripapillary detachment.
Results: The OCT scans identified a peripapillary detachment in 42 eyes (17.21%). Out of these 42 eyes, 22 showed PIC (52.38%; group A) and 20 had a PNRD (47.62%; group B). The average overall RNFL thickness in groups A, B and C was 74.11 ± 10.88, 88.26 ± 25.72 and 72.75 ± 16.24 μm, respectively (ANOVA test, p = 0.00).
Conclusion: Eyes with a PNRD had a significantly greater average RFNL thickness than those without peripapillary detachment in pathologic myopia due to a misidentification of the outer profile of the RFNL. This fact makes the interpretation of RNFL thickness in highly myopic eyes more challenging.

Purpose: To observe the changes in peripapillary retinal nerve fiber layer (RNFL) thickness and peripapillary vessel densities (VD) in patients with rhegmatogenous retinal detachment (RRD) after scleral buckling (SB) by OCTA.
Methods: A total of 40 patients (40 eyes) with monocular RRD who underwent SB were included in the study, with the operated eyes (40 eyes) as the study group and the contralateral healthy eyes (40 eyes) as the control to analyse the changes in peripapillary RNFL thickness and VD before and after surgery. Data were analysed by paired samples -test or Wilcoxon signed rank sum test.

Background: This study aims to examine vessel density changes in the optic nerve and macula following silicone oil removal (SOR) surgery in eyes with rhegmatogenous retinal detachment (RRD) at different time points by Optical Coherence Tomography Angiography (OCTA) in compared to the contralateral eye.
Methods: A total of 43 eyes from 43 patients with silicone oil in their eyes for 3-9 months underwent OCT-A using AngioVue and optic disc-associated vessel density (VD) and thickness, macular-associated VD and thickness, Foveal avascular zone (FAZ) area, FAZ perimeter (PERIM), Acircularity index (AI), vessel density within a 300 μm wide region of the FAZ were compared between eyes. OCTA scans were performed one week before SOR and one month and three months after SOR.
