Mydriasis and glaucoma: Exploding the myth. A systematic review

Abstract

Aims: To investigate the risk of inducing acute glaucoma following mydriasis. Methods: Systematic review of published research 1933-1999. Results: The risk of inducing acute glaucoma following mydriasis with tropicamide alone is close to zero, no case being identified. The risk with long-acting or combined agents is between 1 in 3380 and 1 in 20 000. The presence of chronic glaucoma constitutes no additional risk. Conclusions: Mydriasis with tropicamide alone is safe even in people with chronic glaucoma. It should be advised in all patients when thorough retinal examination is indicated.
