as a statistical tool to compare outcomes by epiretinal membrane stages, but each of these groups differ significantly in the best-corrected visual acuity at baseline and, hence, cannot be expected to reach similar levels of the visual acuity at the end of 12 months.2 A better option could have been clinical if the authors could have either compared the absolute change in the visual acuity or adjusted for the baseline acuity. The authors want to use this classification scheme as a single prognostic criterion for epiretinal membrane surgery but have not analyzed the other outer retinal layer biomarkers which are equally important to prognosticate such patients. A significant proportion of the patient in this study had outer retinal changes which can also contribute to the results achieved.3 We would like to suggest the authors to perform a multivariate analysis with all prognostic markers and provide relative significance to each including ectopic inner foveal layer staging.
