【Objective】To investigate the morphologic characteristics of idiopathic epiretinal membrane (iERM) and its quantitative analysis method by multi-color image and optical coherence tomography (OCT).【Methods】Ten patients (10 eyes) with iERM were imaged by multi-color image and B-scan OCT

respectively. The morphological characteristics

thickness in the dark and light color area

and area of iERM measured by multi-color image and B-scan OCT image were analysed. The best-corrected visual acuity (BCVA) and central macular thickness were also recorded.【Results】The iERM clearly displayed as yellowish green membrance by multi-color image. The thickness of iERM in the dark color area was thicker than that of the light color area. The area of iERM measured by multi-color image and B-scan OCT image did not show significant difference. The BCVA was negatively related to the central macular thickness.【Conclusion】The multicolor image could observe the iERM intuitively and clearly

and the area measured by multi-color image could been a quantitative evaluation method to monitor the change of iERM.
