“…7 Recently introduced spectral domain OCT (SD-OCT) measures the interferometric signal detected as a function of optical frequencies, allowing for imaging speeds 50 times faster than TD-OCT, and providing a greater number of images per unit area. [8][9][10][11][12] This increase in resolution and scanning speed allows highdensity raster scanning of retinal tissue while minimizing eye motion artefacts. A better repeatability of measurement compared with Stratus OCT has been reported for spectral domain OCT in healthy eyes.…”

“…Investigators have applied OCT to studies on the structural mechanism for macular diseases. [17][18][19][20] With this device, it might show the precise structural changes of macular region. However, it is regrettable that we hadn't used OCT for examining the patients in this study.…”

Background To quantify changes in metamorphopsia and retinal contraction in eyes with idiopathic epiretinal membrane (ERM) before and after a spontaneous separation of ERM. Methods Among 92 eyes of 92 patients with idiopathic ERM who were followed up at our hospital, 5 eyes of 5 patients had experienced a spontaneous separation of ERM during the follow-up period. Patient's metamorphopsia was assessed horizontally and vertically by a metamorphopsia chart developed by our group, M-CHARTS, to obtain the horizontal (MH) and vertical (MV) metamorphopsia scores. Difference in the scores before and after the membrane separation represents change in patient's metamorphopsia. Changes in retinal contraction were also evaluated horizontally and vertically with our original software for fundus image analysis. The difference between M-CHARTS scores and distances of retinal vessel movements with before and after membrane separation were measured. Results All five subjects showed a decrease in the retinal contraction. Improved visual acuity was observed in three subjects, and no change was seen in the other two. Four subjects obtained better metamorphopsia scores after the membrane separation, while the other one was not detected with metamorphopsia by M-CHARTS either before or after the separation. In subjects with an improved MV, horizontal retinal movement

“…Johnson (2005) reported that eyes with idiopathic ERM were found by OCT and or ultrasound to be associated with partial (87%) or complete (13%) PVD. Using 3D OCT, Koizumi et al (2008) detected complete PVD (83%), partial PVD (14%) in eyes with idiopathic ERM. The lower percent of complete PVD in this study may be due to the fact that too anterior PVD is outside the range of imaging of OCT and had to be documented with ultrasound.…”

Purpose: To describe epiretinal membrane (ERM) features using spectral domain optical coherence tomography ''SD OCT'' and to delineate the three-dimensional (3D) relationship in eyes with epiretinal membrane.Methods: Fifty-two eyes of 44 patients with ERM were classified into two groups: idiopathic ERM and secondary ERM. Posterior vitreous face was evaluated. Pattern of ERM attachment was divided into: focal and global. A 3D SD OCT system (5 lm resolution) was used for scanning. Surface maps were used to study retinal topography.Results: Surface maps revealed manner and direction of epiretinal traction, pattern of attachment and blood vessel involvement. In 55.8% of eyes the membrane was globally adherent to the retina. There was a significant association (p = 0.02%) between pattern of membrane attachment and etiological classification of eyes. Posterior vitreous detachment (PVD) was associated with both groups, but no significant difference in between.Conclusion: Spectral domain OCT allowed better characterization of ERM including: visualization, extension, cleavage plane and zones with free edges. Surface maps revealed the topography of ERM and retina pathology. Idiopathic ERM are significantly associated with global pattern. PVD plays an important role in the pathogenesis of primary as well as secondary ERM.
