Background:
Indocyanine green (ICG) staining facilitates definitive internal limiting membrane (ILM) peeling during macular hole surgery (MHS), but might cause toxicity.
Purpose:
To determine if ICG to assist in ILM peeling has an effect on anatomic or visual results in MHS with ILM peeling.
Methods:
Retrospective, comparative review including primary analysis of 173 cases undergoing MHS. Visual acuity >or=20/50,
Results:
The single operation hole closure rate was 87% with ICG versus 83% without ICG (P = 0.52). Postoperative median best-corrected visual acuity was 20/70 and 20/80 in the ICG and no ICG groups with median follow-up intervals of 8 and 9 months. The use of ICG was associated with a higher rate of
Conclusions:
ICG usage during macular hole surgery was not associated with worse visual outcomes, suggesting possible toxic effects reported are not clinically significant. If the ILM cannot be peeled effectively, ICG should be considered a safe option.
