To evaluate quantification of metamorphopsia with novel method and to investigate the correlation between the foveal & parafoveal retinal measurements with spectral-domain optical coherence tomography (SD-OCT) and metamorphopsia in patients with epiretinal membrane(ERM).
Clinical records of 50 patients with ERM were analyzed retrospectively. All subjects underwent SD-OCT using raster scan and metamorphopsia test. Retinal thickness and volume at the fovea (CRT-1mm) and parafovea (CRT-3mm) were measured with SD-OCT software. The severity of metamorphopia was quantified on 21 points using metamorphosia test. Metamorphopsia scores of superior,inferior,temporal, and nasal area were calculated by the scores of 21 points. The correlation between the retinal measurements in each subfield with OCT and metamorphopsia scores were investigated.
Fifty-two eyes of 50 patients with ERM were evaluated. The mean total score of metamorphopsia was 23.1 ± 14.0. Simple regression analysis revealed that total score of metamorphopsia was significantly related to the CRT-1mm(p=0.002) & CRV-1mm(p=0.002). Parafoveal retinal thickness and retinal volume was significantly correlated with metamorphopsia score in each subfield. (p<0.001~0.011)
: Degree of metamorphopsia could be quantified on each subfield by using novel metamorphopsia test. There was significant correlation between degree of metamorphopsia and SD-OCT findings.
