Efficacy of sulfur hexafluoride (SF6) versus perfluoropropane (C3F8) tamponade in large macular hole

Objective: gas tamponade for large idiopathic macular holes. Materials and methods: group (30 eyes of 30 patients). Based on minimal linear diameter (MLD), subjects were further classified into two groups: large (400 - <600 μm) or very large (>600 μm); compared for anatomical closure, improvement in best corrected visual acuity, and development of complications. Results: . Discussion: may be associated with quicker visual recovery in the early postoperative period. However, the long-term visual outcomes are often comparable between the two agents. In the present study, we compared the efficacy of both these tamponade agents for large and very large idiopathic macular holes. Conclusions: tamponade.
