Purpose : To analyse the postoperative anatomical changes of maculae using optical coherent tomography after
internal limiting membrane peeling during vitrectomy.
Methods : A retrospective review of 22 patients (22 eyes) who underwent vitrectomy with internal limiting
membrane peeling was performed. Age, sex, fundus findings, BCVA, operation methods, complications, and
postoperative OCT findings were recorded.
Results : Of 22 eyes, 12 eyes had epiretinal membranes, 5 eyes had macular holes, and 5 eyes had diffuse
diabetic macular edemas. Eighteen of 22 eyes underwent internal limiting membrane peeling using ICG, with
1 eye treated with triamcinolone and 3 eyes treated with nothing. The postoperative improvement of BCVA
was statistically significant in epiretinal membrane and diffuse macular edema patients (p<0.05), but
insignificant in macular hole patients (p>0.05). Postoperative OCT findings of 17 eyes showed that they had
returned to normal shape and thickness. However, among the 18 eyes that underwent ICG dye-assisted ILM,
3 eyes showed irregular macular thinning and 1 eye showed macular cystic changes. One eye treated with
triamcinolone presented with a recurrent cytoid macular edema. No postoperative complications or recurrences
were reported by epiretinal membrane patients.
Conclusion : Changes to macular shape did not significantly affect the final BCVA after internal limiting
membrane peeling, but they can cause changes to the microstructure of maculae. Therefore, caution during
surgery and close follow-up are necessary.
