Abstract

Purpose : Spectralis multicolor (MC, Heiderberg engeneering, Germany) is a new scanning laser ophthalmoscopy with three different wavelengths which can obtain clearer retinal images than conventional color funduscopy (CF). There are a few reports comparing the sensitivity of MC and CF. In addition, the relationship between retinal finding by MC and patient’s vision is not well understood. Thus, the purpose of this study was to compare the sensitivity of MC and CF and to investigate the relationship between morphological findings determined by MC and visual function in patients with epiretinal membrane (ERM).

Methods : A prospective cross-sectional case study was conducted at Kagoshima University Hospital. Patients with ERM from May to October 2017 were enrolled. Severity of ERM by CF or MC were classified as three grades (1-not detectable, 2-barely detectable, 3-clearly detectable, ERM score) by a medical student (MS) or retina specialist (RS). ERM scores detected with different machines by different raters; with CF by with MS, wth CF by RS, with MC by MS, with MC by RS, were analyzed by Steel-Dwass test. The relationship between visual function such as visual acuity (VA, LogMAR) and metamorphology score by M-chart (Inami, Japan) and ERM score of CF and MC by RS is analyzed by spearman’s rank correlation coefficient.

Results : Thirty-six eyes of 33 patients were enrolled. Mean age was 68.1 +/- 8.47, mean VA was 0.20 +/- 0.2 logMAR, mean metamorphology score was 0.42 +/- 0.46. ERM scores of CF was 1.58 +/- 0.68 by MS and 1.88 +/- 0.45 by RS (not significant). ERM scores of MC was 2.78 +/- 0.47 by MS and 2.70 +/- 0.5 by RS, both of them were statistically significant with ERM score of CF by both examiners. Although ERM scores of CF and MC were not significantly correlated with VA, it was significantly correlated with metamorphology score (CP: p=0.03, R=0.37, MC: p=0.006, R=0.46).

Conclusions : Evaluation of ERM by MC is more sensitive than by CF. In addition, MC could suggest the change of visual function more clearly than CF. MC may be a more useful tool for ERM assessment than CF.
