Tamsulosin use may result in "floppy iris" syndrome.
It appears that the muscle controlling the iris has a similarity to the muscles that control the bladder and consequently may be affected in some men.
Men on Tamsulosin are advised to tell their ophthalmic surgeon if they are having an eye operated on.
Although I never experienced any abnormalities of vision in the 10 years I was on Tamsulosin, more than one optician has commented on my pinpoint pupils and asked am I on any recreational drugs like cocaine or heroin and after advising I'm not a junkie, discussions normally ensue which invariably reach a consensus that Tamsulosin has caused my iris muscles to relax to the point where my pupils have become pinpoint.
The only difficulty I experience with this condition is when I attend a diabetic retinopathy session and the pupil dilating solution goes in my eyes and it takes a little longer than normal for them to dilate fully.
