“…The analyses of CMT were inconclusive, to the same extent as previous studies have reported conflicting results related to the association between CMT and visual loss [27,28,29,30,31,32]. All 4 eyes with a decreased EZ signal showed vision loss and ERM progression in our study, and their impaired photoreceptor integrity was related to vision loss [28,29,30].…”

“…All 4 eyes with a decreased EZ signal showed vision loss and ERM progression in our study, and their impaired photoreceptor integrity was related to vision loss [28,29,30]. However, vision loss in 2 eyes with an intact EZ signal would be associated with damage to the inner retinal layers [31,32]. Screening of the EZ signal seems to be insufficient to detect early vision loss.…”

Purpose: To investigate the natural history of idiopathic epiretinal membrane (ERM) in eyes with good visual function using optical coherence tomography (OCT). Methods: Sixty-two eyes of 58 patients with idiopathic ERM, visual acuity of 20/40 or better, and no significant metamorphopsia were included. The best corrected visual acuity (BCVA), central macular thickness (CMT), membrane configuration, and ellipsoid zone signal data over 24 months were retrospectively analyzed. Based on OCT findings, ERM configurations were categorized as global attachment (GA), partial attachment (PA), pseudohole, and vitreomacular traction (VMT). Results: The mean BCVA and CMT did not change significantly between baseline and 24 months. GA, PA, pseudohole, and VMT types were observed in 33, 19, 9, and 1 eye at baseline, and in 20, 22, 10, and 1 eye at 24 months, respectively. A membrane configuration change was noted in 24 eyes (38.7%) during follow-up, and the distribution shifted from GA to the other types (p < 0.001). Six eyes had visual loss due to membrane progression, and 4 eyes had spontaneous membrane separation. Of the 10 eyes with progression or separation, 6 were of the PA type. Conclusions: Although the BCVA remains stable over 2 years in most idiopathic ERM eyes with good visual function at baseline, the membrane configuration may change, affecting visual acuity. The GA type would be an early stage, and the PA type is prone to changes in visual acuity.

“…Previous studies reported good surgical outcomes and many prognostic factors, such as preoperative visual acuity, retinal thickness, photoreceptor layer status, and the status of other specific layers of the retina, for the outcome following ERM surgery [13,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32]. Among these, preoperative vision is a well-known prognostic factor that influences postoperative vision.…”

“…Recently, surgical outcomes, including ERM patients with a vision better than 20/30, were reported [16,33]. They showed that better initial vision resulted in higher postoperative vision, while poorer initial vision resulted in greater vision improvement, and more patients with poor baseline vision experienced vision improvement after surgery [16,33].…”

Purpose: To investigate postoperative visual acuity changes following idiopathic epiretinal membrane (ERM) surgery as well as investigate the relationship between outcome and baseline visual acuity. Methods: The medical records of 159 consecutive eyes were retrospectively reviewed for best corrected visual acuity (BCVA), central subfield macular thickness (CSMT), and the ellipsoid zone (EZ) signal of the photoreceptor layer at baseline and 1, 3, and 6 months after surgery. Patients were divided into two groups: group A, with good vision of 20/50 or better, and group B, with poor visual acuity worse than 20/50. Results: Seventy-nine eyes were included in group A and 80 eyes in group B. Mean baseline BCVA was 0.28 and 0.65 logarithm of the minimum angle of resolution (logMAR), and the mean baseline CSMT was 423.7 and 505.6 μm in group A and group B, respectively. In group A, BCVA worsened to 0.39 logMAR at 1 month (p < 0.001) and gradually improved to 0.25 logMAR at 6 months, which was not different from baseline BCVA. In group B, BCVA and CSMT improved at 1, 3, and 6 months (p < 0.05). The EZ signal improved in group B (p = 0.003) but not in group A. The area under the receiver operating characteristic curve for the improvement in BCVA of ≥2 lines was significant for preoperative BCVA (0.717, 95% confidence interval 0.638-0.797; p < 0.001). The cutoff value was 0.35 on the logMAR scale. Conclusion: After ERM surgery, patients with good vision maintained visual acuity after temporary worsening of vision, and patients with poor vision achieved significant BCVA improvement.

„Zuwarten“ als therapeutisches Prinzip bei Erkrankungen der vitreoretinalen Grenzfläche

Elective surgery of the vitreoretinal interface is currently the most common reason for vitrectomy in Germany. The evaluation and correct interpretation of spectral domain optical coherence tomography (SD-OCT) images is of great importance but the indications for vitrectomy in macular surgery should be based more on patient symptoms and not only the OCT findings. Watchful waiting is highlighted as an alternative therapeutic option in individual patients. This article addresses a number of aspects and discrepancies between findings and patients' level of suffering based on binocular symptoms. Postoperative retinal thickening and irregular surface of the macula after peeling operations may still allow excellent function and often require no therapeutic measures. The difficulties in differentiating between cystoid macular edema after cataract operations with simultaneous epiretinal gliosis and gliosis as the cause of macular edema are highlighted.

Analysis of the ganglion cell layer and photoreceptor layer using optical coherence tomography after idiopathic epiretinal membrane surgery

Abstract: The postoperative ganglion cell layer was found to be correlated to postoperative VA more consistently than the photoreceptor layer after ERM surgery. The outer retinal damage was a determining factor in the poor VA group.
