Mydriasis using tropicamide eye drops alone poses virtually no risk of acute glaucoma, even for patients with chronic glaucoma. Combined or long-acting agents carry a small risk, making tropicamide the preferred choice for safe retinal exams.

Area of Science:

  • Ophthalmology
  • Clinical Pharmacology

Background:

  • Mydriasis is essential for comprehensive retinal examination.
  • The risk of inducing acute glaucoma with mydriatic agents is a clinical concern.

Purpose of the Study:

  • To systematically evaluate the incidence of acute glaucoma secondary to mydriasis.
  • To compare the safety profiles of different mydriatic agents.

Main Methods:

  • A systematic review of published literature from 1933 to 1999.
  • Analysis of case reports and studies documenting glaucoma induction post-mydriasis.

Main Results:

  • Tropicamide monotherapy demonstrated a near-zero risk of inducing acute glaucoma.
  • Long-acting or combination mydriatic agents were associated with a risk ranging from 1:3,380 to 1:20,000.

  • Pre-existing chronic glaucoma did not increase the risk of mydriasis-induced acute glaucoma.

    • Conclusions:

    • Mydriasis induced by tropicamide alone is a safe procedure, even in patients with pre-existing chronic glaucoma.
    • Tropicamide monotherapy is recommended for all patients requiring mydriasis for retinal examination.
    • This finding supports the routine use of tropicamide for diagnostic purposes in ophthalmology.
