Topical phenylephrine causes temporary lens opacities in mice. These eye changes resolve within 24 hours and can be prevented by eye ointment, indicating dehydration is the likely cause.

Area of Science:

  • Ophthalmology
  • Pharmacology
  • Toxicology

Background:

  • Topical phenylephrine is commonly used in ophthalmic practice.
  • Potential ocular side effects of phenylephrine require thorough investigation.

Purpose of the Study:

  • To investigate the effects of topical 10% phenylephrine on mouse eyes.
  • To elucidate the mechanism behind phenylephrine-induced lens opacities.

Main Methods:

  • Administration of topical 10% phenylephrine to various mouse strains.
  • Observation of lens and ocular tissues for opacities.
  • Intervention with eye ointment to assess preventative effects.

Main Results:

  • Topical 10% phenylephrine induced transient lens opacities in mice.

  • Opacities resolved spontaneously within 24 hours.
  • Ointment application prevented phenylephrine-induced lens opacification.

    • Conclusions:

    • Topical phenylephrine can cause reversible lens opacities in mice.
    • The mechanism is likely related to transcorneal dehydration.
    • These findings highlight a potential, transient side effect of phenylephrine use.
