For 6 years my IOPs have gone up & down,but were always the same in each
eye. For the past month I started using Cosopt in one eye,twice a day,&
Lumigan in both at bedtime. Yesterday I was checked & IOPs were 19,down
from 23, in both eyes. Is there a way Cosopt would affect the untreated
eye? Doctor couldn't explain it,but was pleased
& told me to do just as I had been doing. He had previously wanted me
to use it in both eyes.Lora

Hello Lora,

You do not say if you were already on Lumigan.
If not, it just sounds like the Cosopt does nothing.

I am on only Lumigan for the past 8 months and very pleased with it.
Before that I was on both Xalatan (pretty good) and Alphagan (caused awful
allergic reaction).
My initial IOP was over 40. Now it is around 16.

For many years now we have seen a response in IOP to beta blockers
(which include timolol or Cosopt) in the untreated eye. I've never
seen a clear explanation for this. Some feel it may work
systemically, as beta blockers are absorbed into the blood stream via
the nose & throat. Nevertheless, it is a well-known phenomenon that
no one seems to complain about.
