Abstract
PURPOSE We aimed to quantitatively evaluate metamorphopsia pre- and postoperatively in patients with idiopathic epiretinal membrane(iERM) using M-CHARTS™ and to evaluate the relationship between morphological changes in retinal layers on optical coherence tomography (OCT) and metamorphopsia scores. MATERIALS AND METHODS This prospective study included 42 patients followed in Akdeniz University Hospital Ophthalmology Clinic diagnosed with iERM by fundus examination and OCT between 2020-2022. Detailed ophthalmologic findings, visual acuities, metamorphopsia scores, and OCT parameters of all patients were recorded. The relationship between pre- and postoperative visual acuity, metamorphopsia scores and OCT parameters was investigated. Changes in OCT parameters were compared by evaluating patients with stable or increasing metamorphopsia scores as one group (group1) and patients with decreasing metamorphopsia scores as the other group (group 2). RESULTS In "group 2", preoperative Ganglion Cell Layer+Inner Plexiform Layer (Central) (GCL+IPL (C)) was significantly (P: 0.028) higher than in "group 1". CONCLUSION A statistically significant preoperative thickness difference in the OCT parameters of the GCL+IPL (C) layer was associated with the quantitative metamorphopsia complaints of the patients. The thickness of the preoperative GCL+IPL (C) layer can be considered an important indicator of symptoms of metamorphopsia determining functional success after surgery.

Abstract
PURPOSE The pathology of branch retinal vein occlusion (BRVO), a retinal circulatory disease, is related to monocular metamorphopsia-related vision impairment of the affected eyes, but the association of binocular metamorphopsia in such patients is unclear. This study aimed to examine the frequency of binocular metamorphopsia and its association with the clinical characteristics of patients with BRVO. METHODS A total of 87 patients who were treated for BRVO-associated macular edema (ME) were included in this study. At baseline and 1 and 3 months after the initiation of anti-vascular endothelial growth factor (VEGF) treatment, we quantified metamorphopsia in the affected eyes and binocular metamorphopsia using the M-CHARTS® diagnostic tool. RESULTS At baseline, 53 and 7 patients had metamorphopsia in the affected eyes and binocular metamorphopsia, respectively. Although the visual acuity improved significantly after the initiation of anti-VEGF treatment, the mean M-CHARTS score in the affected eyes did not change from the baseline score. At 3 months, 9 patients showed binocular metamorphopsia; it was significantly associated with metamorphopsia in the affected eyes with a 95% confidence interval of 0.021-0.122 (β = 0.306, p = 0.006). CONCLUSION Metamorphopsia in the affected eyes can cause binocular metamorphopsia in patients with BRVO-ME.

Abstract
Purpose: To discuss the pathophysiology of metamorphopsia, its characterisation using retinal imaging and methods of assessment of patient symptoms and visual function.Methods: A literature search of electronic databases was performedResults: Metamorphopsia has commonly been associated with vitreomacular interface disorders (such as epiretinal membrane) and has also regularly been noted in diseases of the retina and choroid, particularly age-related macular degeneration and central serous chorioretinopathy. Developments in optical coherence tomography retinal imaging have enabled improved imaging of the foveal microstructure and have led to the localisation of the pathophysiology of metamorphopsia within the retinal layers of the macula. Alteration of alignment of inner and outer retinal layers at various retinal loci has been identified using multimodal imaging in patients with metamorphopsia in a range of conditions. Although the Amsler Grid assessment of metamorphopsia is a useful clinical indicator, new emerging methods of metamorphopsia assessment with psychophysical tests such as M-CHARTS and preferential hyperacuity perimetry, have been developed.Conclusions: It appears that there is a complex relationship between visual acuity and metamorphopsia symptoms that vary between retinal conditions. Although metamorphopsia has traditionally been challenging to measure in the clinic, advances in technology promise more robust, easy-to-use tests. It is possible that home assessment of metamorphopsia, particularly in conditions such as age-related macular degeneration, may help to guide the need for further clinic evaluation and consideration of treatment.

Abstract
PURPOSE To correlate metamorphopsia provided by M-CHARTS and ectopic inner foveal layers (EIFL) or 'central bouquet' abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the novel Optical Coherence Tomography (OCT)-based grading scheme. METHODS In 60 eyes of 57 patients affected by ERM (stages 3 and 4), the degree of metamorphopsia using the M-CHARTS was evaluated (M-SCORE) and correlated with EIFL, CBA and central foveal thickness (CFT) as measured on OCT scans. RESULTS A total of 37 and 23 eyes were diagnosed having ERM stages 3 and 4, respectively. Mean vertical and horizontal M-SCORE (M-V and M-H) were 0.64 ± 0.43 and 0.58 ± 0.37 standard deviations, respectively. Mean M-SCORE exhibited a statistically significant correlation with EIFL and CFT (both p < 0.0001), but not with CBA (p = 0.84). Analysing the direction of metamorphopsia separately, M-H and M-V were significantly correlated with EIFL (both p < 0.0001), but not with CBA thickness (p = 0.70 and 0.33 respectively). Ectopic inner foveal layers (EIFL) was significantly influenced by the presence of CBA (CBA present, 158.29 ± 63.53 micron; CBA absent, 107.05 ± 94.13 micron, p = 0.04). No significant differences were found for both M-V and M-H with respect to the presence of CBA. CONCLUSIONS Based on the novel OCT-based grading scheme for ERMs, our results demonstrate that EIFL, but not CBA, might be considered a good indicator for metamorphopsia in patients with advanced ERMs.

Abstract
PURPOSE To determine the 2-year results of metamorphopsia, visual acuity, and optical coherence tomographic (OCT) parameters after epiretinal membrane (ERM) removal, and to evaluate the correlations among them. METHODS We studied 75 eyes of 75 patients with an ERM who underwent vitrectomy and membrane peeling. The best-corrected visual acuity (BCVA), metamorphopsia scores, and OCT parameters were measured at the baseline, and 1, 3, 6, 9, 12, 18, and 24 months postoperatively. M-CHARTS were used to quantify the degree of metamorphopsia. RESULTS The mean BCVA, degree of metamorphopsia, and all of the OCT parameters except the photoreceptor outer segment (PROS) length improved significantly from that at the baseline at 24 months (P < 0.001). However, they were not significantly different from those at 12 months. The better BCVA at 24 months was correlated with the longer PROS length at the baseline (P < 0.01). The degree of metamorphopsia at 24 months was significantly correlated with that at baseline (P < 0.01). CONCLUSIONS A postoperative follow-up period of 12 months may be sufficient to assess the improvements induced by the ERM surgery. The preoperative PROS length was the prognostic factor for the postoperative BCVA. The preoperative degree of metamorphopsia was the prognostic factor for the postoperative degree of metamorphopsia, suggesting that surgery for ERM should be performed before development of severe metamorphopsia.

Abstract
PURPOSE We quantified the degree and dynamics of metamorphopsia changes in patients subjected to full-thickness macular hole surgery. MATERIAL/METHODS This prospective interventional case series included 10 eyes of 10 patients with full-thickness macular hole (mean age 66.2±6.0 years). The patients underwent a complete ophthalmological examination including SD-OCT. The severity of metamorphopsia (expressed as M-score) was evaluated with M-CHARTS. 20-gauge pars plana vitrectomy with trypan blue staining, internal limiting membrane peeling and 20% sulphur hexafluoride tamponade was performed. Time course of metamorphopsia changes and their relation to best corrected visual acuity (BCVA) and OCT parameters were assessed. RESULTS Significant but not total M-score decrease was observed one month postoperatively (0.72±0.44 vs. 0.50±0.36, z=-2.207, p=0.0353, power=0.26, pre- vs. post-op), with subsequent stabilization (0.41±0.41 three months and 0.37±0.44 six months post-op). The differences between M-score one month, three months and six months postoperatively were not significant. Baseline M-score correlated significantly with postoperative values at three follow-ups (rho=0.853, 0.715, 0.847; p<0.05 for all; power=0.94, 0.58, 0.79). Baseline M-score did not correlate with macular hole dimensions (including basis p=0.154, minimal diameter p=0.051 or height of the border p=0.700). No correlation between M-score and the following parameters was found either pre- or postoperatively: BCVA, central foveal thickness, central subfield macular thickness and central subfield macular volume. CONCLUSIONS In patients with successfully operated full-thickness macular hole, M-score decreased as early as one month postoperatively and was stable afterwards. The baseline M-score was a prognostic factor for the postoperative M-score. M-score turned out to be independent from BCVA and macular hole dimensions.
