    Summary
    This summary is machine-generated.

    Microplasmin, a stable recombinant enzyme, effectively induces posterior vitreous detachment (PVD) for pharmacologic vitreolysis. Preclinical studies of microplasmin supported its clinical investigation in MIVI trials for vitreoretinal surgery.

    Area of Science:

    • Ophthalmology
    • Biochemistry
    • Pharmacology

    Background:

    • Microplasmin is a stabilized recombinant molecule containing the catalytic domain of human plasmin.
    • It exhibits similar catalytic properties to plasmin but offers enhanced stability.
    • Both plasmin and microplasmin have demonstrated the ability to induce posterior vitreous detachment (PVD).

    Purpose of the Study:

    • To focus on microplasmin-assisted vitrectomy as a promising pharmacologic vitreolysis strategy.
    • To review the preclinical research on plasmin and microplasmin.
    • To highlight the progression to clinical trials investigating microplasmin.

    Main Methods:

    • Review of preclinical data on plasmin and microplasmin.
    • Focus on the development of microplasmin for pharmacologic vitreolysis.
