    Summary

    Vitreous surgery using perfluoropropane (C3F8) or perfluoroethane (C2F6) successfully reattached retinas in 55.4% of complicated retinal detachment cases. These longer-lasting gases outperformed previous treatments, offering new hope for retinal reattachment.

    Area of Science:

    • Ophthalmology
    • Surgical Innovation
    • Retinal Surgery

    Background:

    • Complicated retinal detachments pose significant surgical challenges.
    • Previous treatments using air-sulfur hexafluoride mixtures had limited success.
    • Perfluorocarbon gases offer potential advantages in expansion and longevity.

    Purpose of the Study:

    • To evaluate the efficacy of vitreous surgery with perfluorocarbon gases for retinal reattachment.
    • To compare the outcomes of perfluoropropane (C3F8) and perfluoroethane (C2F6) in managing retinal detachments.

    Main Methods:

    • Fifty-six patients with complicated retinal detachments underwent vitreous surgery.
    • Two perfluorocarbon gases, perfluoropropane (C3F8) and perfluoroethane (C2F6), were utilized.
    • Patient outcomes were assessed based on retinal reattachment rates and complications.

    Main Results:

    • Retinal reattachment was achieved in 55.4% of patients (31 out of 56) six months post-procedure.
    • Perfluorocarbon gases demonstrated success in cases where previous air-sulfur hexafluoride surgeries failed.
    • Transient increased intraocular pressure and gas-induced lens opacities were the primary complications.

    Conclusions:

    • Vitreous surgery with perfluorocarbon gases is an effective treatment for complicated retinal detachments.
    • Perfluoropropane and perfluoroethane offer improved longevity and expansion compared to older gases.
    • These gases represent a valuable advancement in retinal reattachment surgery.
