These results indicate that, based on OCT analysis, the double-peeling procedure for idiopathic macular pucker, using triamcinolone to remove the ERM and BBG to remove the ILM, results in a much more effective removal of the ERM within a 3 × 3-mm square centered on the fovea compared with the single-peeling procedure with triamcinolone. We believe that performing OCT 1 month after surgery is the correct time point at which to determine the amount of residual tissue left after membrane peeling and before any significant remodeling at the vitreoretinal interface has occurred. Although OCT evidence of a residual ERM remained in the central foveal area in 52.5% of single-peeling patients, this tissue was present in only 2.5% of double-peeling patients. To our knowledge, the outcomes of ERM-peeling surgery as gauged by OCT have not previously been reported. However, the 3-month visual acuity outcomes did not differ between the 2 groups. This is consistent with previous data using indocyanine green staining of the ILM, which has shown that peeling both the ERM and the ILM may not result in better postoperative visual acuity compared with peeling only the ERM.14 An alternative explanation for our finding may be that visual acuity had not yet stabilized postoperatively at the 3-month time point we examined and that longer-term follow-up of visual acuity may have revealed a significant difference. We examined 3-month postoperative visual acuity to limit confounding effects of postvitrectomy nuclear sclerosis and cataract on visual acuity. In other studies, a longer follow-up did not appear to change the finding that there was a difference in BCVA after ILM peeling.15 However, it has been shown that, following ERM removal, the macular thickness is significantly reduced 3 months after surgery, yet, in some patients, recovery of visual acuity takes at least 9 months.16 Effective ERM removal in the peripheral macula (within a 6 × 6-mm square centered on the fovea but outside a 3 × 3-mm square centered on the fovea) would not be expected to affect visual acuity significantly, and we found no difference between the 2 treatment groups with regard to the presence of a postoperative ERM in this area (ie, 70% of patients in the double-peeling group and 77.5% of patients in the single-peeling group).
