“…ERM at or near the macular region may be associated with visual symptoms, including metamorphopsia, micropsia, and moderate-to-severe visual impairment. 5 It has been previously suggested that the Japanese have a lower prevalence of ERM as compared with white populations. 6 McCarty et al 7 summarized the prevalence of ERM in different populations after direct age standardization, and reported that the prevalence of ERM was lowest in a Japanese population sample (the Hisayama Study, 2.8%) and was highest in a Latino population in the United States (the Los Angeles Latino Eye Study: 19.0%).…”

Purpose To determine the prevalence and risk factors of epiretinal membranes (ERM) in a Japanese population. Patients and Methods The Funagata Study examined 1758 Japanese aged 35 years or older (42% of eligible) from June 2000 to June 2002. A total of 1723 (98.0%) participants had nonmydriatic fundus photographs of the right eye to grade the presence of ERM, using the Blue Mountains Eye Study (BMES) protocol. After age standardization, the prevalence of ERM in the right eyes of the participants included in this study was compared with that reported from right eyes of participants in the BMES and the Beaver Dam Eye Study (BDES). ERM detected in eyes with diabetic retinopathy and other retinal lesions were excluded from the analysis of associations. Multiple logistic regression models were used to determine risk factors for the presence of ERM, adjusting for age and gender. Results There were 84 right eyes with ERM, representing 5.44% of this sample. After age standardization, the prevalence rate (5.7%) was within the range reported in the BMES (3.5%) and the BDES (6.9%). Older age (genderadjusted odds ratio (OR) per 10 years: 1.72, 95% confidence interval (CI): 1.40-2.11) and diabetes (age-gender-adjusted OR: 1.84, 95% CI: 1.01-3.37) were the only two factors associated with ERM. Conclusions We found a similar prevalence of ERM in the Japanese as in mainly white populations. Increasing age and diabetes were risk factors for ERM in this adult Japanese population.

“…[1][2][3] Although most patients with ERM retain stable visual acuity without surgical intervention, in cases of progressing or proliferating membranes that thicken and contract the sensory retina, patients often suffer from severe metamorphopsia. In such cases, patient's severity of metamorphopsia rather than visual acuity might be a better indicator that reveals more precise information on the progression of the disease.…”

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

“…Preoperative incidence of a PVD has generally been reported in 57 to 90% of patients with idiopathic ERM. 1,2 In our recent studies, PVD was noted in 78.5% of eyes with idiopathic ERM. 3 Thus, surgical induction of a PVD during vitreous surgery is not necessary in the majority of ERM cases.…”

Purpose The purpose of this study is to investigate the morphological features of epiretinal membrane (ERM) in the presence or absence of a posterior vitreous detachment (PVD). Design Retrospective observational comparative case series. Methods This study involved 34 patients in whom the vitreoretinal relationship was confirmed during vitrectomy for treatment of ERM. We analyzed demography, direction of macular folds in fundus photographs, and foveal contours assessed by optical coherence tomography (OCT) in two groups of patients, the posterior vitreous attachment (PVA) group and the PVD group. Results Mean age of the 14 patients in the PVA group was 58.2±8.2 years, and that of 20 patients in the PVD group was 66.7±6.7 years (P ¼ 0.0023). Funduscopic examination revealed radiating folds in 57.1% of patients in the PVA group and 10% of patients in the PVD group, and a flat-shaped foveal contour was observed on OCT in 71.5% of patients in the PVA group and 25.0% of patients in the PVD group. Significant differences were observed between the PVA group and the PVD group in both direction of the macular folds (Po0.01) and foveal contours (P ¼ 0.028). Conclusion Patients with ERM and PVA were usually younger than 60 years. Radiating macular folds and flat foveal contour in patients with ERM are highly sensitive and specific findings indicative of PVA.
