Air as tamponade for retinal detachments

Area of Science:

• Ophthalmology
• Retinal Surgery
• Vitreoretinal Diseases

Background:

• Pars plana vitrectomy is a common surgical procedure for retinal detachment (RD).
• Internal tamponade agents are crucial for successful retinal reattachment post-vitrectomy.
• The use of air as a tamponade agent offers potential advantages in specific clinical scenarios.

Purpose of the Study:

• To evaluate the efficacy and safety of filtered air as an internal tamponade agent following pars plana vitrectomy for primary retinal detachment (RD).
• To assess the visual acuity outcomes and tamponade duration associated with air tamponade in RD repair.

Main Methods:

• A prospective study included twelve eyes with fresh primary retinal detachment (RD) meeting specific inclusion criteria.
• Pars plana vitrectomy was performed, followed by endolaser or cryotherapy around all breaks.
• Filtered air was utilized as the internal tamponade, with patients followed for up to 12 months.

Main Results:

• The air bubble resolved in an average of 10.7 days (range 7-15 days).
• Visual acuity (VA) significantly improved from 1.35 ± 1.21 logMAR preoperatively to 0.20 ± 0.25 logMAR at 12 months.
• A high primary postoperative success rate of 100% at 1 month and 91.6% at 12 months was achieved.

Conclusions:

• Filtered air serves as an effective and reliable tamponade agent for primary retinal detachment (RD) after pars plana vitrectomy.
• This approach facilitates rapid visual acuity recovery due to the quick resolution of the air bubble.
• The use of air tamponade may be particularly beneficial for patients residing at higher altitudes.
