Abstract

Purpose: Indocyanine green (ICG) staining of the internal limiting membrane has facilitated ILM peeling in macular hole surgery. However, it has been reported that ICG-assisted peeling of the ILM may result in retinal damage and unfavorable functional outcome. Therefore, we analyzed our visual and anatomical results of ICG assisted macular hole surgery.

Methods: In a retrospective study the records of a consecutive series of 37 patients with full-thickness idiopathic macular holes operated with ICG-assisted ILM peeling by a single surgeon were analyzed. All patients underwent a standard three-port vitrectomy with surgically induced posterior vitreous detachment, staining of the ILM with ICG, peeling of the ILM in a circular manner around the fovea, and SF6 20% endotamponade.

Results: A total of 37 patients (37 eyes) were included in the study. The mean age was 69+/-7 years (range 52-81 years), and there were 26 women and 11 men. The follow-up ranged from 6 to 30 months (mean 18+/-6 months). At baseline visual acuity ranged from 20/400 to 20/40. Anatomically, 13 eyes had stage 2 holes, 21 eyes (57%) stage 3 holes, and three eyes stage 4 holes. At the postoperative visit (8-12 weeks after surgery) anatomical closure of the macular hole was achieved in 36 eyes. Visual acuity ranged between 20/400 and 20/20. At the last follow-up after initial surgery the macular hole was closed in all eyes. Visual acuity ranged from 20/200 to 20/20.

Conclusion: In our retrospective series anatomical and functional results of macular hole surgery with ICG-assisted peeling of the ILM are satisfactory. Primary hole closure was achieved in 97% of eyes and visual acuity increased in 62% of eyes in our series.
