Abstract

To evaluate retinal functional changes after idiopathic macular hole (MH) surgery using heavy

brilliant blue G (hBBG) dye for internal limiting membrane (ILM) staining. Methods: Forty‐four eyes with

idiopathic MH were randomized into two groups – 24 eyes using hBBG staining and 20 eyes without staining; anatomical and functional status (with microperimetry (MP)) at baseline and during postoperative follow‐up were compared. Results: All eyes had closure of MH postoperatively and overall baseline MP indices (average threshold, AT; foveal sensitivity, FS) improved significantly at 6 weeks and 6 months of follow‐up. AT and FS showed significant improvement at 6 weeks and 6 months from baseline in both individual groups (P < 0.001). Intergroup comparison showed that there was no statistically significant difference in AT and FS values at any point of time. Conclusions: Functional parameters of macula improved significantly after successful MH surgery using hBBG for staining the ILM.
