Air vs Gas Tamponade During Macular Hole Repair Surgery

Area of Science:

• Ophthalmology
• Retinal Surgery

Background:

• Full-thickness macular holes (FTMH) are a significant cause of vision loss.
• Surgical repair often involves internal tamponade agents to facilitate hole closure.

Purpose of the Study:

• To compare the efficacy of air versus gas tamponade in full-thickness macular hole (FTMH) repair.
• To evaluate visual and anatomical outcomes following FTMH surgery with different tamponade agents.

Main Methods:

• Retrospective review of 211 patients undergoing pars plana vitrectomy for idiopathic FTMH.
• Analysis of tamponade agents used (gas vs. air) and recorded outcomes.
• Preoperative macular hole size and duration, and postoperative hole closure were assessed.

Main Results:

• No statistically significant difference in mean preoperative macular hole size between air and gas groups (P = .43).
• Hole closure rates were similar: 5.3% failure with gas (171 eyes) vs. 2.5% failure with air (40 eyes) (P = .45).
• Both air and gas tamponades demonstrated comparable efficacy in FTMH repair.

Conclusions:

• Air serves as an equally efficacious internal tamponade agent compared to nonexpansile gas.
• Air is a viable and effective alternative for tamponade in idiopathic FTMH repair surgery.
