“…The mean vertical and horizontal scores were 0.59 ± 0.57 and 0.52 ± 0.67, respectively. Kinoshita et al[ 20 ] reported that an M-CHARTS score of 0.3 to 0.5 may be the threshold for detecting patients with symptomatic metamorphopsia in their daily life. Twenty-five (59.5%) eyes in the current study had M-CHARTS scores equal to or lager than 0.5 at baseline (data not shown).…”

PurposeTo apply M-CHARTS for quantitative measurements of metamorphopsia in eyes with acute branch retinal vein occlusion (BRVO) and to elucidate the pathomorphology that causes metamorphopsia.MethodsThis prospective study consisted of 42 consecutive patients (42 eyes) with acute BRVO. Both at baseline and one month after treatment with ranibizumab, metamorphopsia was measured with M-CHARTS, and the retinal morphological changes were examined with optical coherence tomography.ResultsAt baseline, metamorphopsia was detected in the vertical and/or horizontal directions in 29 (69.0%) eyes; the mean vertical and horizontal scores were 0.59 ± 0.57 and 0.52 ± 0.67, respectively. The maximum inner retinal thickness showed no association with the M-CHARTS score, but the M-CHARTS score was correlated with the total foveal thickness (r = 0.43, p = 0.004), the height of serous retinal detachment (r = 0.31, p = 0.047), and the maximum outer retinal thickness (r = 0.36, p = 0.020). One month after treatment, both the inner and outer retinal thickness substantially decreased. However, metamorphopsia persisted in 26 (89.7%) of 29 eyes. The posttreatment M-CHARTS score was not correlated with any posttreatment morphological parameters. However, the posttreatment M-CHARTS score was weakly correlated with the baseline total foveal thickness (r = 0.35. p = 0.024) and closely correlated with the baseline M-CHARTS score (r = 0.78, p < 0.001).ConclusionsMetamorphopsia associated with acute BRVO was quantified using M-CHARTS. Initial microstructural changes in the outer retina from acute BRVO may primarily account for the metamorphopsia.

“…Similarly, Nakagawa et al[ 6 ] reported that the M-CHARTS score was unchanged of 6 months in 12 eyes with acute BRVO. Metamorphopsia due to various diseases has been reported to be decreased as a result of treatment [ 5 , 20 , 24 , 29 ]. However, metamorphopsia from BRVO tends to persist even after complete resolution of the ME.…”

“…We did not investigate M-CHARTS before RFPDT because we were unable to assess some patients using M-CHARTS because of central scotoma. The presence of metamorphopsia was defined as a mean M-CHARTS score of �0.5˚at 12 months after RFPDT according to previous reports [8,9].…”

Predictive factors of metamorphopsia after reduced-fluence photodynamic therapy in patients with central serous chorioretinopathy with good baseline visual acuity

et al. 2020

This retrospective study was conducted to investigate the predictive factors associated with metamorphopsia after reduced-fluence photodynamic therapy (RFPDT) in patients with central serous chorioretinopathy (CSC) with good baseline visual acuity. A total of 36 eyes of 36 consecutive patients with resolved CSC after RFPDT and best-corrected visual acuity (BCVA) better than 1.0 (logarithm of the minimal angle of resolution (logMAR) 0) at baseline were examined. Metamorphopsia was measured using M-CHARTS at 12 months after RFPDT. An average of the horizontal and vertical M-CHARTS scores was applied for defining the extent of metamorphopsia. The association between M-CHARTS score at 12 months after RFPDT and clinical parameters (age, sex, duration of symptoms, BCVA, and findings of optical coherence tomography (OCT)) was investigated at baseline or 12 months after RFPDT. The M-CHARTS score at 12 months correlated significantly with duration of symptoms (P = 0.005), baseline outer nuclear layer (ONL) thickness (P = 0.009), central foveal thickness (CFT) (P = 0.001) at 12 months, and ONL thickness (P = 0.001) at 12 months after RFPDT. In the multivariate analysis of baseline-related factors, thinner ONL thickness before RFPDT (P = 0.010) was significantly associated with large metamorphopsia at 12 months after RFPDT in CSC patients with good baseline BCVA. Baseline ONL thickness may be a useful predictive factor of metamorphopsia after RFPDT in CSC patients with good baseline BCVA.

“…[3,4] Various vitreoretinal diseases cause metamorphopsia and aniseikonia; these diseases include epiretinal membrane (ERM), macular hole (MH), and rhegmatogenous retinal detachment (RRD). [5][6][7][8][9][10][11][12] Pars plana vitrectomy (PPV) is an effective treatment for these retinal diseases, and recent advances in PPV have led to improvements in anatomical success and postoperative visual acuity; however, metamorphopsia combined with aniseikonia often persists and causes considerable problems.…”

This study investigated postoperative changes in metamorphopsia and aniseikonia in eyes that underwent vitrectomy for epiretinal membrane (ERM), macular hole (MH), or rhegmatogenous retinal detachment (RRD). In total, 166 eyes were included from 166 patients with ERM, MH, or RRD who underwent primary vitrectomy. Metamorphopsia and aniseikonia were quantified by M-CHARTS and the New Aniseikonia Test (NAT). Best-corrected visual acuity (BCVA), M-CHARTS, NAT assessments, and OCT examination were performed at 1, 3, and 6 months postoperatively. Of the 166 eyes, 65 had ERM, 21 had MH, 42 had macula-off RRD, and 38 had macula-on RRD. BCVA improved significantly between 1 and 6 months postoperatively in eyes with ERM, MH, and macula-off RRD (P = 0.0057, P = 0.0065, and P = 0.0021, respectively). M-CHARTS scores at 1 month postoperatively significantly decreased in eyes with ERM (P = 0.0034) and tended to decrease in eyes with MH (P = 0.068). NAT scores did not change between baseline and 1 month postoperatively in eyes with ERM or MH. Between 1 and 6 months postoperatively, M-CHARTS and NAT scores significantly decreased in eyes with macula-off RRD (P = 0.0064 and P = 0.0009, respectively), but not in eyes with ERM, MH, or macula-on RRD. At 6 months postoperatively, significant metamorphopsia was evident in 33.3% of eyes with ERM, 29.2% of eyes with MH, and 35.7% of eyes with macula-off RRD; 61.5% of eyes with ERM showed macropsia and 52.3% of eyes with macula-off RRD showed micropsia. In eyes with ERM, more central retinal thickness (CRT) correlated with postoperative BCVA, and deep retinal folds on enface OCT image correlated with postoperative metamorphopsia. In eyes with maculaoff RRD, less CRT correlated with postoperative BCVA, and tended to correlate with postoperative micropsia. Macular morphologies could contribute to differences in postoperative visual acuity, metamorphopsia, and aniseikonia.
