I have developed viral conjunctivitis in my bad eye.  I am concerned
about what may happen if it spreads to my good eye which has a trab.
My glaucoma specialist is out of town for the holidays, and the
"general" eye doc I saw today thought it would be very unlikely that
the virus could penetrate the conjuntiva to get to the trab (and hence
unlikely that an inner eye infection couild occur).  I'd like opinoins
from glaucoma experts though, since I've read this can happen.  Given
the fact that the viral type of conjuctivitis does not readily respond
to treatment, I'm obviously concerned about what would happen if this
infection somehow spread along my trab.

So, is it indeed very unlikely that the virus would infect a trab?

Are there any effective treatments for such cases and what are the
likely outcomes?

How long does viral conjunctivitis normally last?  I'm being as clean
as possible so as not to spread it to the other eye, but obviously the
sooner it is gone, the better.

Thanks
