TRT, total retinal thickness; TRV, total retinal volume; RPE, retinal pigment epithelium; ONL, outer nuclear layer; OPL, outer plexiform layer; INL, inner nuclear layer; IPL, inner plexiform layer; GCL, ganglion cell layer; RNFL, retinal nerve fiber layer. Difference with preoperative measurement statistically significant using the Bonferroni correction. The differences between the mean RPE values were significant according to repeated measure results, but the Bonferroni test did not reveal a significant change. The Bonferroni test did not reveal a significant change between the preoperative and postoperative mean ONL values. However, the decrease in the mean value in the postoperative first day has resulted in a significant difference between the mean first day value and the mean 3rd month value with Bonferroni correction.
