Context : Surgical outcomes of vitrectomy for idiopathic macular hole using a "heavy" Brilliant Blue G (HBBG) solution for staining and removal of the internal limiting membrane (ILM). Settings and Design : Prospective interventional case series conducted in a tertiary eye care hospital. Materials and Methods : Nineteen patients (20 eyes) with idiopathic macular hole were enrolled to undergo vitrectomy with ILM peeling using HBBG. BBG dye was made heavy by mixing with 10% dextrose normal saline (DNS) solution in 2:1 ratio. The adequacy of ILM staining was noted intraoperatively. The closure rates of macular hole and visual improvement were recorded. Patients were followed up postoperatively on day 1, week 1, and subsequently at 1, 3, and 6 months, and every 6th month thereafter. Statistical Analysis: Wilcoxon signed-rank test was used; P < 0.05 was considered significant. Results: Preoperative best-corrected visual acuity (BCVA) ranged from 20/1000 to 20/63 (median: 20/100). Intraoperatively, the ILM stained very well in all eyes, and was easily removed. All macular holes closed postoperatively. The mean follow-up was 6.15 ± 2 months (range: 4-10; median: 6 months). Final BCVA ranged from 20/20 to 20/80 (median: 20/40), amounting to a significant visual improvement (P = 0.0001). BCVA improved by 1-8 Snellen lines in 19 eyes (95%); 16 eyes (80%) improved by ≥2 lines; 13 eyes (65%) achieved a final BCVA of 20/40 or better. Conclusions : Addition of 10% DNS to BBG dye allowed good ILM staining with less dye during macular hole surgery, and provided excellent anatomic and visual outcomes.
