It has previously been implicated as a causative agent in intra-operative floppy iris syndrome due to its effects on the smooth muscle. We report a case of lower lid entropion that may be related to a patient commencing treatment of tamsulosin. Case presentation A 74-year-old Caucasian man was started on alpha 1-a receptor antagonist Tamsulosin treatment for benign prostatic hypertrophy. Eight days later he presented to the ophthalmology unit with a right lower lid entropion which was successfully treated surgically with a Weiss procedure. Conclusion We report a case of lower lid entropion that may be secondary to the recent use of an alpha-1a blocker tamsulosin . This can be explained by considering the effect of autonomic blockade on alpha-1 receptors in the Muller s muscle on a patient that may already have an anatomical predisposition to entropion formation due to a further reduction in muscle tone. Introduction The use of alpha-la receptor antagonists tamsulosin is widely accepted in the treatment of benign prostatic hypertrophy BPH . It has previously been implicated as a causative agent in the intra-operative floppy iris syndrome due to its effects on smooth muscle. We report a case of lower lid entropion that may be related to a patient commencing treatment with tamsulosin. Case presentation A 74-year-old Caucasian man presented to the ophthalmology outpatient clinic with a five-day history of a heavy and sore right eye.
