“…In addition, compared to the findings reported in [6], the baseline BCVA and the reading ability of the patients in this study were better. Our findings of improved reading ability, together with the previously reported improvement in contrast sensitivity [22], parafoveal retinal sensitivity [23], and stereopsis [24], suggest that along with the increased widespread use of OCT and MIVS in the clinical setting, it is justifiable to expand the surgical indication of ERM when compared with the previous standard of 20G vitreous surgery.…”

“…We did not find a correlation between the metamorphopsia score and BCVA either. Given that ERM surgery reportedly improves not only metamorphopsia but also contrast sensitivity [22], parafoveal retinal sensitivity [23], and stereopsis [24], we were unable to elucidate whether the improvement in CPS is caused by any one of those factors or by multiple factors. Third, in this study, we did not include a correlation between reading ability parameters and structural retinal changes.…”

Evaluation of pre- and post-surgery reading ability in patients with epiretinal membrane: a prospective observational study

et al. 2020

Background: This study aimed to investigate the pre-and post-surgery reading ability in patients with idiopathic epiretinal membrane (ERM) to evaluate whether measurement of reading performance is a helpful test in addition to visual acuity (VA) as an assessment measure. Methods: This prospective observational study involved 42 eyes of 40 patients with idiopathic ERM. Best-corrected visual acuity (BCVA), reading ability, and metamorphopsia score were evaluated at baseline and at 3, 6, and 12 months post-surgery. As the outcome measure, the reading ability of each patient (i.e., overall performance) was examined with MNREAD-J, the Japanese version of the MNREAD reading acuity (RA) charts, to determine RA, critical print size (CPS), and maximum reading speed (MRS). Generally, a difference of 0.2 logMAR or more is considered a significant change in BCVA. Thus, as a subgroup analysis, we additionally evaluated the BCVA and reading ability of the patients with a BCVA difference of 0.1 logMAR or less between at baseline and at 12 months post-surgery. Results: Relative to their values at baseline, the subjects exhibited significantly improved BCVA, RA, and CPS throughout the post-surgery examination period (P < 0.001) and significantly improved MRS at 12 months postsurgery (P = 0.04). No significant change in the vertical metamorphopsia score was observed throughout the postsurgery follow-up period. However, and compared to the value at baseline, significant improvements in the horizontal metamorphopsia score were observed at 3, 6 (P < 0.05), and 12 months (P < 0.001) post-surgery. In the subgroup analysis of the 23 eyes that exhibited a BCVA improvement of 0.1 logMAR or less, the median BCVA did not change, but the median RA and CPS improved by 0.2 logMAR. Conclusions: Our findings showed that the surgical removal of ERM improves reading ability, even when the BCVA score does not improve. The measurement of reading performance appears to be a helpful test in addition to VA as a measure for assessing the surgical removal of ERM.

KEYWORDS epiretinal membrane, good visual acuity, metamorphopsia, aniseikonia, vitrectomy 2 Abstract Purpose: To evaluate the efficacy of epiretinal membrane removal in patients with good bestcorrected visual acuity (BCVA) for improving visual function and quality of life (QOL). Methods: This prospective case study compared 37 subjects with preoperative BCVA≦logMAR0.046 (Good group) to 35 patients with logMAR BCVA 0.52-0.10 (Moderate group) at 3 and 6 months. Linear mixed-effect models were used for statistical analysis. The primary outcome was the horizontal metamorphopsia score (MH) at 6 months postoperatively (post-6 M), while secondary outcomes were postoperative BCVA, vertical metamorphopsia score (MV), aniseikonia, stereopsis and central foveal thickness. In the Good group, QOL was assessed using the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) at 6 and 12 months. Results: MH was significantly improved at post-3 M and post-6 M in the both groups but there were no significant differences between the two groups. MV showed no improvement at the final observation in either group. LogMAR BCVA was significantly improved at post-6 M in the Good group, which had significantly better vision than the Moderate group. Preoperative vertical and horizontal aniseikonia scores remained unchanged in the Good group at post-6 M but worsened in the Moderate group. The NEI VFQ-25 score improved in the Good group, reflecting improved general health, general vision, and mental health. Conclusions: Early epiretinal surgery was effective for MH, BCVA, aniseikonia, and QOL. BackgroundEpiretinal membrane is a translucent tissue that develops on the retinal surface and is reportedly present in 7%-11.8% individuals age 40 years and older [1,2]. Epidemiological studies conducted on the Japanese population have found that 4.0%-5.4% of individuals have epiretinal membranes, indicating that aging is a risk factor [3,4]. A recent study utilizing optical coherence tomography showed an epiretinal membrane to be present in 8.6% of post-cataract surgery patients with a mean age of 74.9 years [5]. Thus, patients with epiretinal membrane will increase as the population ages.Although the epiretinal membrane itself does not cause blindness, symptoms of metamorphopsia and aniseikonia will develop. Furthermore, best-corrected visual acuity (BCVA) will decrease with the progression of these clinical conditions. It has been reported that preoperative BCVA is associated

The NEI VFQ-25 score improved in the Good group, reflecting improved general health, general vision, and mental health. Conclusions: Early epiretinal surgery for patients with BCVA ≦ 0.046 logMAR was effective for improvement of HM, BCVA, and QOL and prevented worsening of aniseikonia.
