    Summary
    This summary is machine-generated.

    Etomidate, an intravenous hypnotic, rapidly reduces intraocular pressure (IOP) in patients. Even low doses effectively lowered IOP, demonstrating its potential for ophthalmic procedures.

    Area of Science:

    • Anesthesiology
    • Ophthalmology
    • Pharmacology

    Background:

    • Intraocular pressure (IOP) management is critical in various medical scenarios.
    • Etomidate is an intravenous hypnotic agent with potential applications in reducing IOP.

    Purpose of the Study:

    • To evaluate the effect of etomidate on intraocular pressure (IOP).
    • To determine the efficacy of etomidate in lowering IOP in a patient cohort.

    Main Methods:

    • Fifty patients received intravenous etomidate.
    • Intraocular pressure (IOP) was measured before and after etomidate administration.
    • A subset of twenty patients received low-dose etomidate (0.25 mg/kg).

    Main Results:

    • Etomidate significantly reduced mean IOP from 15.7 to 9.5 mmHg within 30 seconds.

  • Low-dose etomidate (0.25 mg/kg) also effectively lowered IOP from 15.6 to 7.6 mmHg.
  • The IOP reduction was independent of muscle movement.
  • Five patients experienced low-frequency pendular nystagmus.

    • Conclusions:

    • Etomidate is a potent agent for rapidly decreasing intraocular pressure (IOP).
    • Its IOP-lowering effect is dose-dependent and occurs quickly after intravenous administration.
    • Etomidate's efficacy suggests potential utility in procedures where IOP reduction is beneficial.
