Enzymes can be used during vitrectomy surgery to improve outcomes by liquefying vitreous humor and detaching the vitreous cortex. This review explores enzymes as intraoperative agents for better vitreoretinal surgery.

Area of Science:

  • Ophthalmology
  • Biochemistry

Background:

  • The vitreoretinal interface is crucial in blinding diseases.
  • Current surgical techniques aim to improve outcomes and avoid vitrectomy.

Purpose of the Study:

  • To review the use of enzymes as intraoperative adjunctive agents in vitrectomy.
  • To discuss enzymes that aid in vitreous liquefaction and cortex detachment.

Main Methods:

  • Review of literature on enzymatic agents in ophthalmic surgery.
  • Analysis of enzymes like plasmin, dispase, chondroitinase, and hyaluronidase.

Main Results:

  • Enzymes can liquefy vitreous humor, facilitating vitreous hemorrhage clearance.
  • Enzymes weaken vitreous cortex adhesion to the internal limiting membrane.

  • Hyaluronidase aids in posterior vitreous detachment and vitreous liquefaction.

    • Conclusions:

    • Enzymatic agents offer a promising adjunctive approach in vitrectomy.
    • Pharmacological vitrectomy can enhance surgical ease and patient outcomes.
    • Further research into enzyme applications may lead to novel treatments for blinding conditions.
